Introduction

cmake-modules - Reference of available CMake modules.

------------------------------------------------------------------------------
Description

The "cmake" executable is the CMake command-line interface.  It may be used
to configure projects in scripts.  Project configuration settings may be
specified on the command line with the -D option.  The -i option will cause
cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator.  Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt.  Users build a
project by using CMake to generate a build system for a native tool on their
platform.

------------------------------------------------------------------------------
Standard CMake Modules

The following modules are provided with CMake.  They can be used with
INCLUDE(ModuleName).

  CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existance of headers to name just
a few.

  AddFileDependencies
       ADD_FILE_DEPENDENCIES(source_file depend_files...)

       Adds the given files as dependencies to source_file


  BundleUtilities
       Functions to help assemble a standalone bundle application.

       A collection of CMake utility functions useful for dealing with .app
       bundles on the Mac and bundle-like directories on any OS.

       The following functions are provided by this module:

          fixup_bundle
          copy_and_fixup_bundle
          verify_app
          get_bundle_main_executable
          get_dotapp_dir
          get_bundle_and_executable
          get_bundle_all_executables
          get_item_key
          clear_bundle_keys
          set_bundle_key_values
          get_bundle_keys
          copy_resolved_item_into_bundle
          copy_resolved_framework_into_bundle
          fixup_bundle_item
          verify_bundle_prerequisites
          verify_bundle_symlinks

       Requires CMake 2.6 or greater because it uses function, break and
       PARENT_SCOPE.  Also depends on GetPrerequisites.cmake.

         FIXUP_BUNDLE(<app> <libs> <dirs>)

       Fix up a bundle in-place and make it standalone, such that it can be
       drag-n-drop copied to another machine and run on that machine as long
       as all of the system libraries are compatible.

       If you pass plugins to fixup_bundle as the libs parameter, you should
       install them or copy them into the bundle before calling fixup_bundle.
       The "libs" parameter is a list of libraries that must be fixed up, but
       that cannot be determined by otool output analysis.  (i.e., plugins)

       Gather all the keys for all the executables and libraries in a bundle,
       and then, for each key, copy each prerequisite into the bundle.  Then
       fix each one up according to its own list of prerequisites.

       Then clear all the keys and call verify_app on the final bundle to
       ensure that it is truly standalone.

         COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

       Makes a copy of the bundle <src> at location <dst> and then fixes up
       the new copied bundle in-place at <dst>...

         VERIFY_APP(<app>)

       Verifies that an application <app> appears valid based on running
       analysis tools on it.  Calls "message(FATAL_ERROR" if the application
       is not verified.

         GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

       The result will be the full path name of the bundle's main executable
       file or an "error:" prefixed string if it could not be determined.

         GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

       Returns the nearest parent dir whose name ends with ".app" given the
       full path to an executable.  If there is no such parent dir, then
       simply return the dir containing the executable.

       The returned directory may or may not exist.

         GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

       Takes either a ".app" directory name or the name of an executable
       nested inside a ".app" directory and returns the path to the ".app"
       directory in <bundle_var> and the path to its main executable in
       <executable_var>

         GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

       Scans the given bundle recursively for all executable files and
       accumulates them into a variable.

         GET_ITEM_KEY(<item> <key_var>)

       Given a file (item) name, generate a key that should be unique
       considering the set of libraries that need copying or fixing up to
       make a bundle standalone.  This is essentially the file name including
       extension with "." replaced by "_"

       This key is used as a prefix for CMake variables so that we can
       associate a set of variables with a given item based on its key.

         CLEAR_BUNDLE_KEYS(<keys_var>)

       Loop over the list of keys, clearing all the variables associated with
       each key.  After the loop, clear the list of keys itself.

       Caller of get_bundle_keys should call clear_bundle_keys when done with
       list of keys.

         SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
                               <copyflag>)

       Add a key to the list (if necessary) for the given item.  If added,
       also set all the variables associated with that key.

         GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

       Loop over all the executable and library files within the bundle (and
       given as extra <libs>) and accumulate a list of keys representing
       them.  Set values associated with each key such that we can loop over
       all of them and copy prerequisite libs into the bundle and then do
       appropriate install_name_tool fixups.

         COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

       Copy a resolved item into the bundle if necessary.  Copy is not
       necessary if the resolved_item is "the same as" the
       resolved_embedded_item.

         COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

       Copy a resolved framework into the bundle if necessary.  Copy is not
       necessary if the resolved_item is "the same as" the
       resolved_embedded_item.

       By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set.  If you want
       full frameworks embedded in your bundles, set
       BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle.  By
       default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework
       dylib itself plus the framework Resources directory.

         FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

       Get the direct/non-system prerequisites of the resolved embedded item.
       For each prerequisite, change the way it is referenced to the value of
       the _EMBEDDED_ITEM keyed variable for that prerequisite.  (Most likely
       changing to an "@executable_path" style reference.)

       This function requires that the resolved_embedded_item be "inside" the
       bundle already.  In other words, if you pass plugins to fixup_bundle
       as the libs parameter, you should install them or copy them into the
       bundle before calling fixup_bundle.  The "libs" parameter is a list of
       libraries that must be fixed up, but that cannot be determined by
       otool output analysis.  (i.e., plugins)

       Also, change the id of the item being fixed up to its own
       _EMBEDDED_ITEM value.

       Accumulate changes in a local variable and make *one* call to
       install_name_tool at the end of the function with all the changes at
       once.

       If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
       marked writable before install_name_tool tries to change them.

         VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

       Verifies that the sum of all prerequisites of all files inside the
       bundle are contained within the bundle or are "system" libraries,
       presumed to exist everywhere.

         VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

       Verifies that any symlinks found in the bundle point to other files
       that are already also in the bundle...  Anything that points to an
       external file causes this function to fail the verification.

  CMakeAddFortranSubdirectory
       Use MinGW gfortran from VS if a fortran compiler is not found.

       The 'add_fortran_subdirectory' function adds a subdirectory to a
       project that contains a fortran only sub-project.  The module will
       check the current compiler and see if it can support fortran.  If no
       fortran compiler is found and the compiler is MSVC, then this module
       will find the MinGW gfortran.  It will then use an external project to
       build with the MinGW tools.  It will also create imported targets for
       the libraries created.  This will only work if the fortran code is
       built into a dll, so BUILD_SHARED_LIBS is turned on in the project.
       In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib
       files are created.  Usage is as follows:

         cmake_add_fortran_subdirectory(
          <subdir>                # name of subdirectory
          PROJECT <project_name>  # project name in subdir top CMakeLists.txt
          ARCHIVE_DIR <dir>       # dir where project places .lib files
          RUNTIME_DIR <dir>       # dir where project places .dll files
          LIBRARIES <lib>...      # names of library targets to import
          LINK_LIBRARIES          # link interface libraries for LIBRARIES
           [LINK_LIBS <lib> <dep>...]...
          CMAKE_COMMAND_LINE ...  # extra command line flags to pass to cmake
          NO_EXTERNAL_INSTALL     # skip installation of external project
          )

       Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with
       respect to the build directory corresponding to the source directory
       in which the function is invoked.

       Limitations:

       NO_EXTERNAL_INSTALL is required for forward compatibility with a
       future version that supports installation of the external project
       binaries during "make install".

  CMakeBackwardCompatibilityCXX
       define a bunch of backwards compatibility variables

         CMAKE_ANSI_CXXFLAGS - flag for ansi c++ 
         CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
         INCLUDE(TestForANSIStreamHeaders)
         INCLUDE(CheckIncludeFileCXX)
         INCLUDE(TestForSTDNamespace)
         INCLUDE(TestForANSIForScope)


  CMakeDependentOption
       Macro to provide an option dependent on other options.

       This macro presents an option to the user only if a set of other
       conditions are true.  When the option is not presented a default value
       is used, but any value set by the user is preserved for when the
       option is presented again.  Example invocation:

         CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                                "USE_BAR;NOT USE_ZOT" OFF)

       If USE_BAR is true and USE_ZOT is false, this provides an option
       called USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO to
       OFF.  If the status of USE_BAR or USE_ZOT ever changes, any value for
       the USE_FOO option is saved so that when the option is re-enabled it
       retains its old value.

  CMakeDetermineVSServicePack
       Includes a public function for assisting users in trying to determine
       the

       Visual Studio service pack in use.

       Sets the passed in variable to one of the following values or an empty
       string if unknown.

           vc80
           vc80sp1
           vc90
           vc90sp1
           vc100
           vc100sp1

       

       Usage: ===========================

           if(MSVC)
              include(CMakeDetermineVSServicePack)
              DetermineVSServicePack( my_service_pack )

       

              if( my_service_pack )
                  message(STATUS "Detected: ${my_service_pack}")
              endif()
           endif()

       

       ===========================

  CMakeExpandImportedTargets
        

       CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN

                                            [CONFIGURATION <config>] )

       

       CMAKE_EXPAND_IMPORTED_TARGETS() takes a list of libraries and replaces
       all imported targets contained in this list with their actual file
       paths of the referenced libraries on disk, including the libraries
       from their link interfaces.  If a CONFIGURATION is given, it uses the
       respective configuration of the imported targets if it exists.  If no
       CONFIGURATION is given, it uses the first configuration from
       ${CMAKE_CONFIGURATION_TYPES} if set, otherwise ${CMAKE_BUILD_TYPE}.
       This macro is used by all Check*.cmake files which use TRY_COMPILE()
       or TRY_RUN() and support CMAKE_REQUIRED_LIBRARIES , so that these
       checks support imported targets in CMAKE_REQUIRED_LIBRARIES:

           cmake_expand_imported_targets(expandedLibs LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}
                                                      CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )


  CMakeFindFrameworks
       helper module to find OSX frameworks

  CMakeFindPackageMode
        

       This file is executed by cmake when invoked with --find-package.  It
       expects that the following variables are set using -D:

          NAME = name of the package
          COMPILER_ID = the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc.
          LANGUAGE = language for which the result will be used, i.e. C/CXX/Fortan/ASM
          MODE = EXIST : only check for existance of the given package
                 COMPILE : print the flags needed for compiling an object file which uses the given package
                 LINK : print the flags needed for linking when using the given package
          QUIET = if TRUE, don't print anything


  CMakeForceCompiler
        

       This module defines macros intended for use by cross-compiling
       toolchain files when CMake is not able to automatically detect the
       compiler identification.

       Macro CMAKE_FORCE_C_COMPILER has the following signature:

          CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
       variable CMAKE_C_COMPILER_ID to the given compiler-id.  It also
       bypasses the check for working compiler and basic compiler information
       tests.

       Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

          CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
       internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id.  It
       also bypasses the check for working compiler and basic compiler
       information tests.

       Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

          CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake
       internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id.
       It also bypasses the check for working compiler and basic compiler
       information tests.

       So a simple toolchain file could look like this:

          INCLUDE (CMakeForceCompiler)
          SET(CMAKE_SYSTEM_NAME Generic)
          CMAKE_FORCE_C_COMPILER   (chc12 MetrowerksHicross)
          CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)


  CMakePackageConfigHelpers
       CONFIGURE_PACKAGE_CONFIG_FILE(), WRITE_BASIC_PACKAGE_VERSION_FILE()

       

           CONFIGURE_PACKAGE_CONFIG_FILE(<input> <output> INSTALL_DESTINATION <path>
                                                          [PATH_VARS <var1> <var2> ... <varN>]
                                                          [NO_SET_AND_CHECK_MACRO]
                                                          [NO_CHECK_REQUIRED_COMPONENTS_MACRO])

       

       CONFIGURE_PACKAGE_CONFIG_FILE() should be used instead of the plain
       CONFIGURE_FILE() command when creating the <Name>Config.cmake or
       <Name>-config.cmake file for installing a project or library.  It
       helps making the resulting package relocatable by avoiding hardcoded
       paths in the installed Config.cmake file.

       In a FooConfig.cmake file there may be code like this to make the
       install destinations know to the using project:

          set(FOO_INCLUDE_DIR   "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
          set(FOO_DATA_DIR   "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )
          set(FOO_ICONS_DIR   "@CMAKE_INSTALL_PREFIX@/share/icons" )
          ...logic to determine installedPrefix from the own location...
          set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )

       All 4 options shown above are not sufficient, since the first 3
       hardcode the absolute directory locations, and the 4th case works only
       if the logic to determine the installedPrefix is correct, and if
       CONFIG_INSTALL_DIR contains a relative path, which in general cannot
       be guaranteed.  This has the effect that the resulting FooConfig.cmake
       file would work poorly under Windows and OSX, where users are used to
       choose the install location of a binary package at install time,
       independent from how CMAKE_INSTALL_PREFIX was set at build/cmake time.

       Using CONFIGURE_PACKAGE_CONFIG_FILE() helps.  If used correctly, it
       makes the resulting FooConfig.cmake file relocatable.  Usage:

          1. write a FooConfig.cmake.in file as you are used to
          2. insert a line containing only the string "@PACKAGE_INIT@"
          3. instead of SET(FOO_DIR "@SOME_INSTALL_DIR@"), use SET(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")
             (this must be after the @PACKAGE_INIT@ line)
          4. instead of using the normal CONFIGURE_FILE(), use CONFIGURE_PACKAGE_CONFIG_FILE()

       

       The <input> and <output> arguments are the input and output file, the
       same way as in CONFIGURE_FILE().

       The <path> given to INSTALL_DESTINATION must be the destination where
       the FooConfig.cmake file will be installed to.  This can either be a
       relative or absolute path, both work.

       The variables <var1> to <varN> given as PATH_VARS are the variables
       which contain install destinations.  For each of them the macro will
       create a helper variable PACKAGE_<var...>.  These helper variables
       must be used in the FooConfig.cmake.in file for setting the installed
       location.  They are calculated by CONFIGURE_PACKAGE_CONFIG_FILE() so
       that they are always relative to the installed location of the
       package.  This works both for relative and also for absolute
       locations.  For absolute locations it works only if the absolute
       location is a subdirectory of CMAKE_INSTALL_PREFIX.

       By default configure_package_config_file() also generates two helper
       macros, set_and_check() and check_required_components() into the
       FooConfig.cmake file.

       set_and_check() should be used instead of the normal set() command for
       setting directories and file locations.  Additionally to setting the
       variable it also checks that the referenced file or directory actually
       exists and fails with a FATAL_ERROR otherwise.  This makes sure that
       the created FooConfig.cmake file does not contain wrong references.
       When using the NO_SET_AND_CHECK_MACRO, this macro is not generated
       into the FooConfig.cmake file.

       check_required_components(<package_name>) should be called at the end
       of the FooConfig.cmake file if the package supports components.  This
       macro checks whether all requested, non-optional components have been
       found, and if this is not the case, sets the Foo_FOUND variable to
       FALSE, so that the package is considered to be not found.  It does
       that by testing the Foo_<Component>_FOUND variables for all requested
       required components.  When using the NO_CHECK_REQUIRED_COMPONENTS
       option, this macro is not generated into the FooConfig.cmake file.

       For an example see below the documentation for
       WRITE_BASIC_PACKAGE_VERSION_FILE().

       

         WRITE_BASIC_PACKAGE_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion|ExactVersion) )

       

       Writes a file for use as <package>ConfigVersion.cmake file to
       <filename>.  See the documentation of FIND_PACKAGE() for details on
       this.

           filename is the output filename, it should be in the build tree.
           major.minor.patch is the version number of the project to be installed

       The COMPATIBILITY mode AnyNewerVersion means that the installed
       package version will be considered compatible if it is newer or
       exactly the same as the requested version.  This mode should be used
       for packages which are fully backward compatible, also across major
       versions.  If SameMajorVersion is used instead, then the behaviour
       differs from AnyNewerVersion in that the major version number must be
       the same as requested, e.g.  version 2.0 will not be considered
       compatible if 1.0 is requested.  This mode should be used for packages
       which guarantee backward compatibility within the same major version.
       If ExactVersion is used, then the package is only considered
       compatible if the requested version matches exactly its own version
       number (not considering the tweak version).  For example, version
       1.2.3 of a package is only considered compatible to requested version
       1.2.3.  This mode is for packages without compatibility guarantees.
       If your project has more elaborated version matching rules, you will
       need to write your own custom ConfigVersion.cmake file instead of
       using this macro.

       Internally, this macro executes configure_file() to create the
       resulting version file.  Depending on the COMPATIBLITY, either the
       file BasicConfigVersion-SameMajorVersion.cmake.in or
       BasicConfigVersion-AnyNewerVersion.cmake.in is used.  Please note that
       these two files are internal to CMake and you should not call
       configure_file() on them yourself, but they can be used as starting
       point to create more sophisticted custom ConfigVersion.cmake files.

       

       Example using both configure_package_config_file() and
       write_basic_package_version_file(): CMakeLists.txt:

          set(INCLUDE_INSTALL_DIR include/ ... CACHE )
          set(LIB_INSTALL_DIR lib/ ... CACHE )
          set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE )
          ...
          include(CMakePackageConfigHelpers)
          configure_package_config_file(FooConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake
                                        INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake
                                        PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR)
          write_basic_package_version_file(${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                                           VERSION 1.2.3
                                           COMPATIBILITY SameMajorVersion )
          install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                  DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake )

       

       With a FooConfig.cmake.in:

          set(FOO_VERSION x.y.z)
          ...
          @PACKAGE_INIT@
          ...
          set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@")
          set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@")

       

          check_required_components(Foo)


  CMakeParseArguments
        

       CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
       <multi_value_keywords> args...)

       CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
       for parsing the arguments given to that macro or function.  It
       processes the arguments and defines a set of variables which hold the
       values of the respective options.

       The <options> argument contains all options for the respective macro,
       i.e.  keywords which can be used when calling the macro without any
       value following, like e.g.  the OPTIONAL keyword of the install()
       command.

       The <one_value_keywords> argument contains all keywords for this macro
       which are followed by one value, like e.g.  DESTINATION keyword of the
       install() command.

       The <multi_value_keywords> argument contains all keywords for this
       macro which can be followed by more than one value, like e.g.  the
       TARGETS or FILES keywords of the install() command.

       When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
       keywords listed in <options>, <one_value_keywords> and
       <multi_value_keywords> a variable composed of the given <prefix>
       followed by "_" and the name of the respective keyword.  These
       variables will then hold the respective value from the argument list.
       For the <options> keywords this will be TRUE or FALSE.

       All remaining arguments are collected in a variable
       <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
       whether your macro was called with unrecognized parameters.

       As an example here a my_install() macro, which takes similar arguments
       as the real install() command:

          function(MY_INSTALL)
            set(options OPTIONAL FAST)
            set(oneValueArgs DESTINATION RENAME)
            set(multiValueArgs TARGETS CONFIGURATIONS)
            cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
            ...

       

       Assume my_install() has been called like this:

          my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)

       

       After the cmake_parse_arguments() call the macro will have set the
       following variables:

          MY_INSTALL_OPTIONAL = TRUE
          MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
          MY_INSTALL_DESTINATION = "bin"
          MY_INSTALL_RENAME = "" (was not used)
          MY_INSTALL_TARGETS = "foo;bar"
          MY_INSTALL_CONFIGURATIONS = "" (was not used)
          MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"

       

       You can the continue and process these variables.

       Keywords terminate lists of values, e.g.  if directly after a
       one_value_keyword another recognized keyword follows, this is
       interpreted as the beginning of the new option.  E.g.
       my_install(TARGETS foo DESTINATION OPTIONAL) would result in
       MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
       would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

  CMakePrintSystemInformation
       print system information

       This file can be used for diagnostic purposes just include it in a
       project to see various internal CMake variables.

  CMakePushCheckState
        

       This module defines two macros: CMAKE_PUSH_CHECK_STATE() and
       CMAKE_POP_CHECK_STATE() These two macros can be used to save and
       restore the state of the variables CMAKE_REQUIRED_FLAGS,
       CMAKE_REQUIRED_DEFINITIONS, CMAKE_REQUIRED_LIBRARIES and
       CMAKE_REQUIRED_INCLUDES used by the various Check-files coming with
       CMake, like e.g.  check_function_exists() etc.  The variable contents
       are pushed on a stack, pushing multiple times is supported.  This is
       useful e.g.  when executing such tests in a Find-module, where they
       have to be set, but after the Find-module has been executed they
       should have the same value as they had before.

       Usage:

          cmake_push_check_state()
          set(CMAKE_REQUIRED_DEFINITIONS ${CMAKE_REQUIRED_DEFINITIONS} -DSOME_MORE_DEF)
          check_function_exists(...)
          cmake_pop_check_state()


  CMakeVerifyManifest
        

       CMakeVerifyManifest.cmake

       This script is used to verify that embeded manifests and side by side
       manifests for a project match.  To run this script, cd to a directory
       and run the script with cmake -P.  On the command line you can pass in
       versions that are OK even if not found in the .manifest files.  For
       example, cmake -Dallow_versions=8.0.50608.0
       -PCmakeVerifyManifest.cmake could be used to allow an embeded manifest
       of 8.0.50608.0 to be used in a project even if that version was not
       found in the .manifest file.

  CPack
       Build binary and source package installers.

       The CPack module generates binary and source installers in a variety
       of formats using the cpack program.  Inclusion of the CPack module
       adds two new targets to the resulting makefiles, package and
       package_source, which build the binary and source installers,
       respectively.  The generated binary installers contain everything
       installed via CMake's INSTALL command (and the deprecated
       INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

       For certain kinds of binary installers (including the graphical
       installers on Mac OS X and Windows), CPack generates installers that
       allow users to select individual application components to install.
       See CPackComponent module for that.

       The CPACK_GENERATOR variable has different meanings in different
       contexts.  In your CMakeLists.txt file, CPACK_GENERATOR is a *list of
       generators*: when run with no other arguments, CPack will iterate over
       that list and produce one package for each generator.  In a
       CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming
       a single generator*.  If you need per-cpack- generator logic to
       control *other* cpack settings, then you need a
       CPACK_PROJECT_CONFIG_FILE.

       The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
       See the top level file CMakeCPackOptions.cmake.in for an example.

       If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a
       per-generator basis.  It only need contain overrides.

       Here's how it works:

         - cpack runs
         - it includes CPackConfig.cmake
         - it iterates over the generators listed in that file's
           CPACK_GENERATOR list variable (unless told to use just a
           specific one via -G on the command line...)

       

         - foreach generator, it then
           - sets CPACK_GENERATOR to the one currently being iterated
           - includes the CPACK_PROJECT_CONFIG_FILE
           - produces the package for that generator

       

       This is the key: For each generator listed in CPACK_GENERATOR in
       CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to
       *the one currently being used* and then include the
       CPACK_PROJECT_CONFIG_FILE.

       Before including this CPack module in your CMakeLists.txt file, there
       are a variety of variables that can be set to customize the resulting
       installers.  The most commonly-used variables are:

         CPACK_PACKAGE_NAME - The name of the package (or application). If
         not specified, defaults to the project name.

       

         CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g.,
         "Kitware").

       

         CPACK_PACKAGE_VERSION_MAJOR - Package major Version

       

         CPACK_PACKAGE_VERSION_MINOR - Package minor Version

       

         CPACK_PACKAGE_VERSION_PATCH - Package patch Version

       

         CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
         project. Used, for example, the introduction screen of a
         CPack-generated Windows installer to describe the project.

       

         CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
         project (only a few words).

       

         CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
         not including the extension. For example, cmake-2.6.1-Linux-i686.
         The default value is
         ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.

       

         CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
         target system. This may be used by some CPack generators
         like NSIS to create an installation directory e.g., "CMake 2.5"
         below the installation prefix. All installed element will be
         put inside this directory.

       

          CPACK_PACKAGE_ICON - A branding image that will be displayed inside
          the installer (used by GUI installers).

       

         CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration
         file. This file included at cpack time, once per
         generator after CPack has set CPACK_GENERATOR to the actual generator
         being used. It allows per-generator setting of CPACK_* variables at
         cpack time.

       

         CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It
         will typically be displayed to the user by the produced installer
         (often with an explicit "Accept" button, for graphical installers)
         prior to installation. This license file is NOT added to installed
         file but is used by some CPack generators like NSIS. If you want
         to install a license file (may be the same as this one)
         along with your project you must add an appropriate CMake INSTALL
         command in your CMakeLists.txt.

       

         CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It
         typically describes in some detail the purpose of the project
         during the installation. Not all CPack generators uses
         this file.

       

         CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the
         installer. It welcomes users to this installer.
         Typically used in the graphical installers on Windows and Mac OS X.

       

         CPACK_MONOLITHIC_INSTALL - Disables the component-based
         installation mechanism. When set the component specification is ignored
         and all installed items are put in a single "MONOLITHIC" package.
         Some CPack generators do monolithic packaging by default and
         may be asked to do component packaging by setting
         CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.

       

         CPACK_GENERATOR - List of CPack generators to use. If not
         specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,
         CPACK_BINARY_NSIS) allowing the user to enable/disable individual
         generators. This variable may be used on the command line
         as well as in:

       

           cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree

       

         CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration
         file. This file is the CPack configuration generated by the CPack module
         for binary installers. Defaults to CPackConfig.cmake.

       

         CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated
         text label to be used to create Start Menu shortcuts. For example,
         setting this to the list ccmake;CMake will
         create a shortcut named "CMake" that will execute the installed
         executable ccmake. Not all CPack generators use it (at least NSIS and
         OSXX11 do).

       

         CPACK_STRIP_FILES - List of files to be stripped. Starting with
         CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
         enables stripping of all files (a list of files evaluates to TRUE
         in CMake, so this change is compatible).

       

       The following CPack variables are specific to source packages, and
       will not affect binary packages:

         CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For
         example cmake-2.6.1.

       

         CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
         will be stripped. Starting with CMake 2.6.0
         CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
         stripping of all files (a list of files evaluates to TRUE in CMake,
         so this change is compatible).

       

         CPACK_SOURCE_GENERATOR - List of generators used for the source
         packages. As with CPACK_GENERATOR, if this is not specified then
         CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
         allowing users to select which packages will be generated.

       

         CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack source
         configuration file. This file is the CPack configuration generated by the
         CPack module for source installers. Defaults to CPackSourceConfig.cmake.

       

         CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
         that won't be packaged when building a source package. This is a
         list of regular expression patterns (that must be properly escaped),
         e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

       

       The following variables are for advanced uses of CPack:

         CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
         project is CMake project. Defaults to the value of CMAKE_GENERATOR
         few users will want to change this setting.

       

         CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
         what project to install. The four values are: Build directory,
         Project Name, Project Component, Directory. If omitted, CPack will
         build an installer that installers everything.

       

         CPACK_SYSTEM_NAME - System name, defaults to the value of
         ${CMAKE_SYSTEM_NAME}.

       

         CPACK_PACKAGE_VERSION - Package full version, used internally. By
         default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
         CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

       

         CPACK_TOPLEVEL_TAG - Directory for the installed files.

       

         CPACK_INSTALL_COMMANDS - Extra commands to install components.

       

         CPACK_INSTALLED_DIRECTORIES - Extra directories to install.

       

          CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
          installing this project. This is only used
          by installer for Windows.
          CPACK_CREATE_DESKTOP_LINKS - List of desktop links to create.

       


  CPackBundle
       CPack Bundle generator (Mac OS X) specific options

       

       Installers built on Mac OS X using the Bundle generator use the
       aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following
       Bundle-specific parameters (CPACK_BUNDLE_xxx).

         CPACK_BUNDLE_NAME - The name of the generated bundle. This
         appears in the OSX finder as the bundle name. Required.

       

         CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
         for the generated bundle. This assumes that the caller has generated
         or specified their own Info.plist file. Required.

       

         CPACK_BUNDLE_ICON - Path to an OSX icon file that will be used as
         the icon for the generated bundle. This is the icon that appears in the
         OSX finder for the bundle, and in the OSX dock when the bundle is opened.
         Required.

       

         CPACK_BUNDLE_STARTUP_COMMAND - Path to a startup script. This is a path to
         an executable or script that will be run whenever an end-user double-clicks
         the generated bundle in the OSX Finder. Optional.


  CPackComponent
       Build binary and source package installers

       

       The CPackComponent module is the module which handles the component
       part of CPack.  See CPack module for general information about CPack.

       For certain kinds of binary installers (including the graphical
       installers on Mac OS X and Windows), CPack generates installers that
       allow users to select individual application components to install.
       The contents of each of the components are identified by the COMPONENT
       argument of CMake's INSTALL command.  These components can be
       annotated with user-friendly names and descriptions, inter-component
       dependencies, etc., and grouped in various ways to customize the
       resulting installer.  See the cpack_add_* commands, described below,
       for more information about component-specific installations.

       Component-specific installation allows users to select specific sets
       of components to install during the install process.  Installation
       components are identified by the COMPONENT argument of CMake's INSTALL
       commands, and should be further described by the following CPack
       commands:

         CPACK_COMPONENTS_ALL - The list of component to install.

       

         The default value of this variable is computed by CPack
         and contains all components defined by the project. The
         user may set it to only include the specified components.

       

         CPACK_<GENNAME>_COMPONENT_INSTALL - Enable/Disable component install for
         CPack generator <GENNAME>.

       

         Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy
         default behavior. e.g. RPM builds monolithic whereas NSIS builds component.
         One can change the default behavior by setting this variable to 0/1 or OFF/ON.
         CPACK_COMPONENTS_GROUPING - Specify how components are grouped for multi-package
         component-aware CPack generators.

       

         Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates several
         packages files when asked for component packaging. They group the component
         differently depending on the value of this variable:
            - ONE_PER_GROUP (default): creates one package file per component group
            - ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
            - IGNORE : creates one package per component, i.e. IGNORE component group
         One can specify different grouping for different CPack generator by using
         a CPACK_PROJECT_CONFIG_FILE.
         CPACK_COMPONENT_<compName>_DISPLAY_NAME - The name to be displayed for a component.
         CPACK_COMPONENT_<compName>_DESCRIPTION - The description of a component.
         CPACK_COMPONENT_<compName>_GROUP - The group of a component.
         CPACK_COMPONENT_<compName>_DEPENDS - The dependencies (list of components)
         on which this component depends.
         CPACK_COMPONENT_<compName>_REQUIRED - True is this component is required.
          cpack_add_component - Describes a CPack installation component
          named by the COMPONENT argument to a CMake INSTALL command.

       

            cpack_add_component(compname
                                [DISPLAY_NAME name]
                                [DESCRIPTION description]
                                [HIDDEN | REQUIRED | DISABLED ]
                                [GROUP group]
                                [DEPENDS comp1 comp2 ... ]
                                [INSTALL_TYPES type1 type2 ... ]
                                [DOWNLOADED]
                                [ARCHIVE_FILE filename])

       

          The cmake_add_component command describes an installation
          component, which the user can opt to install or remove as part of
          the graphical installation process. compname is the name of the
          component, as provided to the COMPONENT argument of one or more
          CMake INSTALL commands.

       

          DISPLAY_NAME is the displayed name of the component, used in
          graphical installers to display the component name. This value can
          be any string.

       

          DESCRIPTION is an extended description of the component, used in
          graphical installers to give the user additional information about
          the component. Descriptions can span multiple lines using "\n" as
          the line separator. Typically, these descriptions should be no
          more than a few lines long.

       

          HIDDEN indicates that this component will be hidden in the
          graphical installer, so that the user cannot directly change
          whether it is installed or not.

       

          REQUIRED indicates that this component is required, and therefore
          will always be installed. It will be visible in the graphical
          installer, but it cannot be unselected. (Typically, required
          components are shown greyed out).

       

          DISABLED indicates that this component should be disabled
          (unselected) by default. The user is free to select this component
          for installation, unless it is also HIDDEN.

       

          DEPENDS lists the components on which this component depends. If
          this component is selected, then each of the components listed
          must also be selected. The dependency information is encoded
          within the installer itself, so that users cannot install
          inconsitent sets of components.

       

          GROUP names the component group of which this component is a
          part. If not provided, the component will be a standalone
          component, not part of any component group. Component groups are
          described with the cpack_add_component_group command, detailed
          below.

       

          INSTALL_TYPES lists the installation types of which this component
          is a part. When one of these installations types is selected, this
          component will automatically be selected. Installation types are
          described with the cpack_add_install_type command, detailed below.

       

          DOWNLOADED indicates that this component should be downloaded
          on-the-fly by the installer, rather than packaged in with the
          installer itself. For more information, see the cpack_configure_downloads
          command.

       

          ARCHIVE_FILE provides a name for the archive file created by CPack
          to be used for downloaded components. If not supplied, CPack will
          create a file with some name based on CPACK_PACKAGE_FILE_NAME and
          the name of the component. See cpack_configure_downloads for more
          information.

       

          cpack_add_component_group - Describes a group of related CPack
          installation components.

       

            cpack_add_component_group(groupname
                                     [DISPLAY_NAME name]
                                     [DESCRIPTION description]
                                     [PARENT_GROUP parent]
                                     [EXPANDED]
                                     [BOLD_TITLE])

       

          The cpack_add_component_group describes a group of installation
          components, which will be placed together within the listing of
          options. Typically, component groups allow the user to
          select/deselect all of the components within a single group via a
          single group-level option. Use component groups to reduce the
          complexity of installers with many options. groupname is an
          arbitrary name used to identify the group in the GROUP argument of
          the cpack_add_component command, which is used to place a
          component in a group. The name of the group must not conflict with
          the name of any component.

       

          DISPLAY_NAME is the displayed name of the component group, used in
          graphical installers to display the component group name. This
          value can be any string.

       

          DESCRIPTION is an extended description of the component group,
          used in graphical installers to give the user additional
          information about the components within that group. Descriptions
          can span multiple lines using "\n" as the line
          separator. Typically, these descriptions should be no more than a
          few lines long.

       

          PARENT_GROUP, if supplied, names the parent group of this group.
          Parent groups are used to establish a hierarchy of groups,
          providing an arbitrary hierarchy of groups.

       

          EXPANDED indicates that, by default, the group should show up as
          "expanded", so that the user immediately sees all of the
          components within the group. Otherwise, the group will initially
          show up as a single entry.

       

          BOLD_TITLE indicates that the group title should appear in bold,
          to call the user's attention to the group.

       

          cpack_add_install_type - Add a new installation type containing a
          set of predefined component selections to the graphical installer.

       

            cpack_add_install_type(typename
                                   [DISPLAY_NAME name])

       

          The cpack_add_install_type command identifies a set of preselected
          components that represents a common use case for an
          application. For example, a "Developer" install type might include
          an application along with its header and library files, while an
          "End user" install type might just include the application's
          executable. Each component identifies itself with one or more
          install types via the INSTALL_TYPES argument to
          cpack_add_component.

       

          DISPLAY_NAME is the displayed name of the install type, which will
          typically show up in a drop-down box within a graphical
          installer. This value can be any string.

       

          cpack_configure_downloads - Configure CPack to download selected
          components on-the-fly as part of the installation process.

       

            cpack_configure_downloads(site
                                      [UPLOAD_DIRECTORY dirname]
                                      [ALL]
                                      [ADD_REMOVE|NO_ADD_REMOVE])

       

          The cpack_configure_downloads command configures installation-time
          downloads of selected components. For each downloadable component,
          CPack will create an archive containing the contents of that
          component, which should be uploaded to the given site. When the
          user selects that component for installation, the installer will
          download and extract the component in place. This feature is
          useful for creating small installers that only download the
          requested components, saving bandwidth. Additionally, the
          installers are small enough that they will be installed as part of
          the normal installation process, and the "Change" button in
          Windows Add/Remove Programs control panel will allow one to add or
          remove parts of the application after the original
          installation. On Windows, the downloaded-components functionality
          requires the ZipDLL plug-in for NSIS, available at:

       

            http://nsis.sourceforge.net/ZipDLL_plug-in

       

          On Mac OS X, installers that download components on-the-fly can
          only be built and installed on system using Mac OS X 10.5 or
          later.

       

          The site argument is a URL where the archives for downloadable
          components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
          All of the archives produced by CPack should be uploaded to that location.

       

          UPLOAD_DIRECTORY is the local directory where CPack will create the
          various archives for each of the components. The contents of this
          directory should be uploaded to a location accessible by the URL given
          in the site argument. If omitted, CPack will use the directory
          CPackUploads inside the CMake binary directory to store the generated
          archives.

       

          The ALL flag indicates that all components be downloaded. Otherwise, only
          those components explicitly marked as DOWNLOADED or that have a specified
          ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
          ADD_REMOVE (unless NO_ADD_REMOVE is specified).

       

          ADD_REMOVE indicates that CPack should install a copy of the installer
          that can be called from Windows' Add/Remove Programs dialog (via the
          "Modify" button) to change the set of installed components. NO_ADD_REMOVE
          turns off this behavior. This option is ignored on Mac OS X.


  CPackCygwin
       Cygwin CPack generator (Cygwin).

       The following variable is specific to installers build on and/or for
       Cygwin:

          CPACK_CYGWIN_PATCH_NUMBER - The Cygwin patch number.
          FIXME: This documentation is incomplete.
          CPACK_CYGWIN_PATCH_FILE - The Cygwin patch file.
          FIXME: This documentation is incomplete.
          CPACK_CYGWIN_BUILD_SCRIPT - The Cygwin build script.
          FIXME: This documentation is incomplete.


  CPackDMG
       DragNDrop CPack generator (Mac OS X).

       The following variables are specific to the DragNDrop installers built
       on Mac OS X:

         CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
         image. Defaults to CPACK_PACKAGE_FILE_NAME.

       

         CPACK_DMG_FORMAT - The disk image format. Common values are UDRO
         (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF
         bzip2-compressed). Refer to hdiutil(1) for more information on
         other available formats.

       

         CPACK_DMG_DS_STORE - Path to a custom DS_Store file. This .DS_Store
         file e.g. can be used to specify the Finder window
         position/geometry and layout (such as hidden toolbars, placement of the
         icons etc.). This file has to be generated by the Finder (either manually or
         through OSA-script) using a normal folder from which the .DS_Store
         file can then be extracted.

       

         CPACK_DMG_BACKGROUND_IMAGE - Path to a background image file. This
         file will be used as the background for the Finder Window when the disk
         image is opened.  By default no background image is set. The background
         image is applied after applying the custom .DS_Store file.

       

         CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
         operate on disk image files on Mac OS X. This variable can be used
         to override the automatically detected command (or specify its
         location if the auto-detection fails to find it.)

       

         CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set
         extended attributes on files and directories on Mac OS X. This
         variable can be used to override the automatically detected
         command (or specify its location if the auto-detection fails to
         find it.)

       

         CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
         resources on Mac OS X. This variable can be used to override the
         automatically detected command (or specify its location if the
         auto-detection fails to find it.)


  CPackDeb
       The builtin (binary) CPack Deb generator (Unix only)

       CPackDeb may be used to create Deb package using CPack.  CPackDeb is a
       CPack generator thus it uses the CPACK_XXX variables used by CPack :
       http://www.cmake.org/Wiki/CMake:CPackConfiguration.  CPackDeb
       generator should work on any linux host but it will produce better deb
       package when Debian specific tools 'dpkg-xxx' are usable on the build
       system.

       CPackDeb has specific features which are controlled by the specifics
       CPACK_DEBIAN_XXX variables.You'll find a detailed usage on the wiki:

         http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29

       However as a handy reminder here comes the list of specific variables:

       CPACK_DEBIAN_PACKAGE_NAME

            Mandatory : YES
            Default   : CPACK_PACKAGE_NAME (lower case)
            The debian package summary

       CPACK_DEBIAN_PACKAGE_VERSION

            Mandatory : YES
            Default   : CPACK_PACKAGE_VERSION
            The debian package version

       CPACK_DEBIAN_PACKAGE_ARCHITECTURE

            Mandatory : YES
            Default   : Output of dpkg --print-architecture (or i386 if dpkg is not found)
            The debian package architecture

       CPACK_DEBIAN_PACKAGE_DEPENDS

            Mandatory : NO
            Default   : -
            May be used to set deb dependencies.

       CPACK_DEBIAN_PACKAGE_MAINTAINER

            Mandatory : YES
            Default   : CPACK_PACKAGE_CONTACT
            The debian package maintainer

       CPACK_DEBIAN_PACKAGE_DESCRIPTION

            Mandatory : YES
            Default   : CPACK_PACKAGE_DESCRIPTION_SUMMARY
            The debian package description

            Default   : OFF
            May be set to ON in order to use dpkg-shlibdeps to generate
            better package dependency list.
            You may need set CMAKE_INSTALL_RPATH toi appropriate value
            if you use this feature, because if you don't dpkg-shlibdeps
            may fail to find your own shared libs.
            See http://www.cmake.org/Wiki/CMake_RPATH_handling.

            the packages named before even starting the installation of the package which declares
            the pre-dependency.

       CPACK_DEBIAN_PACKAGE_ENHANCES

            Mandatory : NO
            Default   : -
            see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
            This field is similar to Suggests but works in the opposite direction.
            It is used to declare that a package can enhance the functionality of another package.

       CPACK_DEBIAN_PACKAGE_BREAKS

            Mandatory : NO
            Default   : -
            see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
            When one binary package declares that it breaks another, dpkg will refuse to allow the
            package which declares Breaks be installed unless the broken package is deconfigured first,
            and it will refuse to allow the broken package to be reconfigured.

       CPACK_DEBIAN_PACKAGE_CONFLICTS

            Mandatory : NO
            Default   : -
            see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
            When one binary package declares a conflict with another using a Conflicts field,
            dpkg will refuse to allow them to be installed on the system at the same time.

       CPACK_DEBIAN_PACKAGE_PROVIDES

            Mandatory : NO
            Default   : -
            see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
            A virtual package is one which appears in the Provides control field of another package.

       CPACK_DEBIAN_PACKAGE_REPLACES

            Mandatory : NO
            Default   : -
            see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
            Packages can declare in their control file that they should overwrite
            files in certain other packages, or completely replace other packages.

          CPACK_NSIS_MODIFY_PATH - Modify PATH toggle.
          If this is set to "ON", then an extra page
          will appear in the installer that will allow the user to choose
          whether the program directory should be added to the system PATH
          variable.

       

          CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
          the Windows Add/Remove Program control panel

       

          CPACK_NSIS_PACKAGE_NAME - The title displayed at the top of the

          uninstall start menu shortcuts.

       

          CPACK_NSIS_EXECUTABLES_DIRECTORY - Creating NSIS start menu links
          assumes that they are in 'bin' unless this variable is set.
          For example, you would set this to 'exec' if your executables are
          in an exec directory.

       

          CPACK_NSIS_MUI_FINISHPAGE_RUN - Specify an executable to add an option
          to run on the finish page of the NSIS installer.
          CPACK_NSIS_MENU_LINKS - Specify links in [application] menu.
          This should contain a list of pair "link" "link name". The link
          may be an URL or a path relative to installation prefix.
          Like:
            set(CPACK_NSIS_MENU_LINKS
                "doc/cmake-@CMake_VERSION_MAJOR@.@CMake_VERSION_MINOR@/cmake.html" "CMake Help"
                "http://www.cmake.org" "CMake Web Site")


  CPackPackageMaker
       PackageMaker CPack generator (Mac OS X).

       The following variable is specific to installers build on Mac OS X
       using PackageMaker:

         CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
         resulting PackageMaker archive should be compatible with. Different
         versions of Mac OS X support different
         features. For example, CPack can only build component-based
         installers for Mac OS X 10.4 or newer, and can only build
         installers that download component son-the-fly for Mac OS X 10.5
         or newer. If left blank, this value will be set to the minimum
         version of Mac OS X that supports the requested features. Set this
         variable to some value (e.g., 10.4) only if you want to guarantee
         that your installer will work on that version of Mac OS X, and
         don't mind missing extra features available in the installer
         shipping with later versions of Mac OS X.


  CPackRPM
       The builtin (binary) CPack RPM generator (Unix only)

       CPackRPM may be used to create RPM package using CPack.  CPackRPM is a
       CPack generator thus it uses the CPACK_XXX variables used by CPack :
       http://www.cmake.org/Wiki/CMake:CPackConfiguration

       However CPackRPM has specific features which are controlled by the
       specifics CPACK_RPM_XXX variables.  CPackRPM is a component aware
       generator so when CPACK_RPM_COMPONENT_INSTALL is ON some more
       CPACK_RPM_<ComponentName>_XXXX variables may be used in order to have
       component specific values.  Note however that <componentName> refers
       to the **grouping name**.  This may be either a component name or a
       component GROUP name.  Usually those vars correspond to RPM spec file
       entities, one may find information about spec files here
       http://www.rpm.org/wiki/Docs.  You'll find a detailed usage of
       CPackRPM on the wiki:

         http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

       However as a handy reminder here comes the list of specific variables:

         CPACK_RPM_PACKAGE_SUMMARY - The RPM package summary.
            Mandatory : YES
            Default   : CPACK_PACKAGE_DESCRIPTION_SUMMARY
         CPACK_RPM_PACKAGE_NAME - The RPM package name.
            Mandatory : YES
            Default   : CPACK_PACKAGE_NAME
         CPACK_RPM_PACKAGE_VERSION - The RPM package version.
            Mandatory : YES
            Default   : CPACK_PACKAGE_VERSION
         CPACK_RPM_PACKAGE_ARCHITECTURE - The RPM package architecture.
            Mandatory : NO
            Default   : -
            This may be set to "noarch" if you
            know you are building a noarch package.
         CPACK_RPM_PACKAGE_RELEASE - The RPM package release.
            Mandatory : YES
            Default   : 1
            This is the numbering of the RPM package
            itself, i.e. the version of the packaging and not the version of the
            content (see CPACK_RPM_PACKAGE_VERSION). One may change the default
            value if the previous packaging was buggy and/or you want to put here
            a fancy Linux distro specific numbering.
         CPACK_RPM_PACKAGE_LICENSE - The RPM package license policy.
            Mandatory : YES
            Default   : "unknown"
         CPACK_RPM_PACKAGE_GROUP - The RPM package group.
            Mandatory : YES
            Default   : "unknown"
         CPACK_RPM_PACKAGE_VENDOR - The RPM package vendor.
            Mandatory : YES
            Default   : CPACK_PACKAGE_VENDOR if set or "unknown"
         CPACK_RPM_PACKAGE_URL - The projects URL.
            Mandatory : NO
            Default   : -
         CPACK_RPM_PACKAGE_DESCRIPTION - RPM package description.
            Mandatory : YES
            Default   : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available"
         CPACK_RPM_COMPRESSION_TYPE - RPM compression type.
            Mandatory : NO
            Default   : -
            May be used to override RPM compression type to be used
            to build the RPM. For example some Linux distribution now default
            to lzma or xz compression whereas older cannot use such RPM.
            Using this one can enforce compression type to be used.
            Possible value are: lzma, xz, bzip2 and gzip.
         CPACK_RPM_PACKAGE_REQUIRES - RPM spec requires field.
            Mandatory : NO
            Default   : -
            May be used to set RPM dependencies (requires).
            Note that you must enclose the complete requires string between quotes,
            for example:
            set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")
            The required package list of an RPM file could be printed with
            rpm -qp --requires file.rpm
         CPACK_RPM_PACKAGE_SUGGESTS - RPM spec suggest field.
            Mandatory : NO
            Default   : -
            May be used to set weak RPM dependencies (suggests).
            Note that you must enclose the complete requires string between quotes.
         CPACK_RPM_PACKAGE_PROVIDES - RPM spec provides field.
            Mandatory : NO
            Default   : -
            May be used to set RPM dependencies (provides).
            The provided package list of an RPM file could be printed with
            rpm -qp --provides file.rpm
         CPACK_RPM_PACKAGE_OBSOLETES - RPM spec obsoletes field.
            Mandatory : NO
            Default   : -
            May be used to set RPM packages that are obsoleted by this one.
         CPACK_RPM_PACKAGE_RELOCATABLE - build a relocatable RPM.
            Mandatory : NO
            Default   : CPACK_PACKAGE_RELOCATABLE
            If this variable is set to TRUE or ON CPackRPM will try
            to build a relocatable RPM package. A relocatable RPM may
            be installed using rpm --prefix or --relocate in order to
            install it at an alternate place see rpm(8).
            Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
            If CPACK_SET_DESTDIR is set then you will get a warning message
            but if there is file installed with absolute path you'll get
            unexpected behavior.
         CPACK_RPM_SPEC_INSTALL_POST - [deprecated].
            Mandatory : NO
            Default   : -
            This way of specifying post-install script is deprecated use
            CPACK_RPM_POST_INSTALL_SCRIPT_FILE
            May be used to set an RPM post-install command inside the spec file.
            For example setting it to "/bin/true" may be used to prevent
            rpmbuild to strip binaries.
         CPACK_RPM_SPEC_MORE_DEFINE - RPM extended spec definitions lines.
            Mandatory : NO
            Default   : -
            May be used to add any %define lines to the generated spec file.
         CPACK_RPM_PACKAGE_DEBUG - Toggle CPackRPM debug output.
            Mandatory : NO
            Default   : -
            May be set when invoking cpack in order to trace debug information
            during CPack RPM run. For example you may launch CPack like this
            cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
         CPACK_RPM_USER_BINARY_SPECFILE - A user provided spec file.
            Mandatory : NO
            Default   : -
            May be set by the user in order to specify a USER binary spec file
            to be used by CPackRPM instead of generating the file.
            The specified file will be processed by CONFIGURE_FILE( @ONLY).
         CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE - Spec file template.
            Mandatory : NO
            Default   : -
            If set CPack will generate a template for USER specified binary
            spec file and stop with an error. For example launch CPack like this
            cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
            The user may then use this file in order to hand-craft is own
            binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
         CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
         CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default   : -
            May be used to embed a pre (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %pre or %preun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
             rpm -qp --scripts  package.rpm
         CPACK_RPM_POST_INSTALL_SCRIPT_FILE
         CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default   : -
            May be used to embed a post (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %post or %postun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
             rpm -qp --scripts  package.rpm
         CPACK_RPM_USER_FILELIST
         CPACK_RPM_<COMPONENT>_USER_FILELIST
            Mandatory : NO
            Default   : -
            May be used to explicitly specify %(<directive>) file line
            in the spec file. Like %config(noreplace) or any other directive
            that be found in the %files section. Since CPackRPM is generating
            the list of files (and directories) the user specified files of
            the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
         CPACK_RPM_CHANGELOG_FILE - RPM changelog file.
            Mandatory : NO
            Default   : -
            May be used to embed a changelog in the spec file.
            The refered file will be read and directly put after the %changelog
            section.


  CTest
       Configure a project for testing with CTest/CDash

       Include this module in the top CMakeLists.txt file of a project to
       enable testing with CTest and dashboard submissions to CDash:

          project(MyProject)
          ...
          include(CTest)

       The module automatically creates a BUILD_TESTING option that selects
       whether to enable testing support (ON by default).  After including
       the module, use code like

          if(BUILD_TESTING)
            # ... CMake code to create tests ...
          endif()

       to creating tests when testing is enabled.

       To enable submissions to a CDash server, create a CTestConfig.cmake
       file at the top of the project with content such as

          set(CTEST_PROJECT_NAME "MyProject")
          set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
          set(CTEST_DROP_METHOD "http")
          set(CTEST_DROP_SITE "my.cdash.org")
          set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
          set(CTEST_DROP_SITE_CDASH TRUE)

       (the CDash server can provide the file to a project administrator who
       configures 'MyProject').  Settings in the config file are shared by
       both this CTest module and the CTest command-line tool's dashboard
       script mode (ctest -S).

       While building a project for submission to CDash, CTest scans the
       build output for errors and warnings and reports them with surrounding
       context from the build log.  This generic approach works for all build
       tools, but does not give details about the command invocation that
       produced a given problem.  One may get more detailed reports by adding

          set(CTEST_USE_LAUNCHERS 1)

       to the CTestConfig.cmake file.  When this option is enabled, the CTest
       module tells CMake's Makefile generators to invoke every command in
       the generated build system through a CTest launcher program.
       (Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile
       generators.) During a manual build each launcher transparently runs
       the command it wraps.  During a CTest-driven build for submission to
       CDash each launcher reports detailed information when its command
       fails or warns.  (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is
       convenient, but also adds the launcher overhead even for manual
       builds.  One may instead set it in a CTest dashboard script and add it
       to the CMake cache for the build tree.)

  CTestScriptMode
        

       This file is read by ctest in script mode (-S)

  CheckCCompilerFlag
       Check whether the C compiler supports a given flag.

       CHECK_C_COMPILER_FLAG(<flag> <var>)

         <flag> - the compiler flag
         <var>  - variable to store the result

       This internally calls the check_c_source_compiles macro.  See help for
       CheckCSourceCompiles for a listing of variables that can modify the
       build.

  CheckCSourceCompiles
       Check if given C source compiles and links into an executable

       CHECK_C_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

         <code>       - source code to try to compile, must define 'main'
         <var>        - variable to store whether the source code compiled
         <fail-regex> - fail if test output matches this regex

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

       CHECK_C_SOURCE_RUNS(<code> <var>)

         <code>   - source code to try to compile
         <var>    - variable to store the result
                    (1 for success, empty for failure)

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckCXXCompilerFlag
       Check whether the CXX compiler supports a given flag.

       CHECK_CXX_COMPILER_FLAG(<flag> <var>)

         <flag> - the compiler flag
         <var>  - variable to store the result

       This internally calls the check_cxx_source_compiles macro.  See help
       for CheckCXXSourceCompiles for a listing of variables that can modify
       the build.

  CheckCXXSourceCompiles
       Check if given C++ source compiles and links into an executable

       CHECK_CXX_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

         <code>       - source code to try to compile, must define 'main'
         <var>        - variable to store whether the source code compiled
         <fail-regex> - fail if test output matches this regex

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckCXXSourceRuns
       Check if the given C++ source code compiles and runs.

       CHECK_CXX_SOURCE_RUNS(<code> <var>)

         <code>   - source code to try to compile
         <var>    - variable to store the result

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

  CheckCXXSymbolExists
       Check if a symbol exists as a function, variable, or macro in C++

       CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>)

       Check that the <symbol> is available after including given header
       <files> and store the result in a <variable>.  Specify the list of
       files in one argument as a semicolon-separated list.
       CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as
       opposed to CHECK_SYMBOL_EXISTS(), which works only for C.

       If the header files define the symbol as a macro it is considered
       available and assumed to work.  If the header files declare the symbol
       as a function or variable then the symbol must also be available for
       linking.  If the symbol is a type or enum value it will not be
       recognized (consider using CheckTypeSize or CheckCSourceCompiles).

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

       CHECK_FORTRAN_FUNCTION_EXISTS(FUNCTION VARIABLE)

         FUNCTION - the name of the Fortran function
         VARIABLE - variable to store the result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckFunctionExists
       Check if a C function can be linked

       CHECK_FUNCTION_EXISTS(<function> <variable>)

       Check that the <function> is provided by libraries on the system and
       store the result in a <variable>.  This does not verify that any
       system header file declares the function, only that it can be found at
       link time (considure using CheckSymbolExists).

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckIncludeFile
       macro which checks the include file exists.

       CHECK_INCLUDE_FILE(INCLUDE VARIABLE)

         INCLUDE  - name of include file
         VARIABLE - variable to return result
          

       an optional third argument is the CFlags to add to the compile line or
       you can use CMAKE_REQUIRED_FLAGS

  CheckIncludeFileCXX
       Check if the include file exists.

         CHECK_INCLUDE_FILE_CXX(INCLUDE VARIABLE)

       

         INCLUDE  - name of include file
         VARIABLE - variable to return result
         

       An optional third argument is the CFlags to add to the compile line or
       you can use CMAKE_REQUIRED_FLAGS.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

         VARIABLE - variable to return result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories


  CheckLanguage
       Check if a language can be enabled

       Usage:

         check_language(<lang>)

       where <lang> is a language that may be passed to enable_language()
       such as "Fortran".  If CMAKE_<lang>_COMPILER is already defined the
       check does nothing.  Otherwise it tries enabling the language in a
       test project.  The result is cached in CMAKE_<lang>_COMPILER as the
       compiler that was found, or NOTFOUND if the language cannot be
       enabled.

       Example:

         check_language(Fortran)
         if(CMAKE_Fortran_COMPILER)
           enable_language(Fortran)
         else()
           message(STATUS "No Fortran support")
         endif()


  CheckLibraryExists
       Check if the function exists.

       CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)

         LIBRARY  - the name of the library you are looking for
         FUNCTION - the name of the function
         LOCATION - location where the library should be found
         VARIABLE - variable to store the result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckPrototypeDefinition
       Check if the protoype we expect is correct.

       check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE)

         FUNCTION - The name of the function (used to check if prototype exists)
         PROTOTYPE- The prototype to check.
         RETURN - The return value of the function.
         HEADER - The header files required.
         VARIABLE - The variable to store the result.

       Example:

         check_prototype_definition(getpwent_r
          "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)"
          "NULL"
          "unistd.h;pwd.h"
          SOLARIS_GETPWENT_R)

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckStructHasMember
       Check if the given struct or class has the specified member variable

       CHECK_STRUCT_HAS_MEMBER (STRUCT MEMBER HEADER VARIABLE)

         STRUCT - the name of the struct or class you are interested in
         MEMBER - the member which existence you want to check
         HEADER - the header(s) where the prototype should be declared
         VARIABLE - variable to store the result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories

       

       Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h
       HAVE_TIMEVAL_TV_SEC)

  CheckSymbolExists
       Check if a symbol exists as a function, variable, or macro

       CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

       Check that the <symbol> is available after including given header
       <files> and store the result in a <variable>.  Specify the list of
       files in one argument as a semicolon-separated list.

       If the header files define the symbol as a macro it is considered
       available and assumed to work.  If the header files declare the symbol
       as a function or variable then the symbol must also be available for
       linking.  If the symbol is a type or enum value it will not be
       recognized (consider using CheckTypeSize or CheckCSourceCompiles).  If
       the check needs to be done in C++, consider using
       CHECK_CXX_SYMBOL_EXISTS(), which does the same as
       CHECK_SYMBOL_EXISTS(), but in C++.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckTypeSize
       Check sizeof a type

         CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

       Check if the type exists and determine its size.  On return,
       "HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}"
       holds one of the following:

          <size> = type has non-zero size <size>
          "0"    = type has arch-dependent size (see below)
          ""     = type does not exist

       Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code
       to define the macro "${VARIABLE}" to the size of the type, or leave
       the macro undefined if the type does not exist.

       The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has
       multiple architectures for building OS X universal binaries.  This
       indicates that the type size varies across architectures.  In this
       case "${VARIABLE}_CODE" contains C preprocessor tests mapping from
       each architecture macro to the corresponding type size.  The list of
       architecture macros is stored in "${VARIABLE}_KEYS", and the value for
       each key is stored in "${VARIABLE}-${KEY}".

       If the BUILTIN_TYPES_ONLY option is not given, the macro checks for
       headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results
       in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H.  The type size
       check automatically includes the available headers, thus supporting
       checks of types defined in the headers.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link
         CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include


  CheckVariableExists
       Check if the variable exists.

         CHECK_VARIABLE_EXISTS(VAR VARIABLE)

       

         VAR      - the name of the variable
         VARIABLE - variable to store the result

       

       This macro is only for C variables.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  Dart
       Configure a project for testing with CTest or old Dart Tcl Client

       This file is the backwards-compatibility version of the CTest module.
       It supports using the old Dart 1 Tcl client for driving dashboard
       submissions as well as testing with CTest.  This module should be
       included in the CMakeLists.txt file at the top of a project.  Typical
       usage:

         INCLUDE(Dart)
         IF(BUILD_TESTING)
           # ... testing related CMake code ...
         ENDIF(BUILD_TESTING)

       The BUILD_TESTING option is created by the Dart module to determine
       whether testing support should be enabled.  The default is ON.

  DeployQt4
       Functions to help assemble a standalone Qt4 executable.

       A collection of CMake utility functions useful for deploying Qt4
       executables.

       The following functions are provided by this module:

          write_qt4_conf
          resolve_qt4_paths
          fixup_qt4_executable
          install_qt4_plugin_path
          install_qt4_plugin
          install_qt4_executable

       Requires CMake 2.6 or greater because it uses function and
       PARENT_SCOPE.  Also depends on BundleUtilities.cmake.

         WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)

       Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>.

         RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])

       Loop through <paths_var> list and if any don't exist resolve them
       relative to the <executable_path> (if supplied) or the
       CMAKE_INSTALL_PREFIX.

         FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])

       Copies Qt plugins, writes a Qt configuration file (if needed) and
       fixes up a Qt4 executable using BundleUtilities so it is standalone
       and can be drag-and-drop copied to another machine as long as all of
       the system libraries are compatible.

       <executable> should point to the executable to be fixed-up.

       <qtplugins> should contain a list of the names or paths of any Qt
       plugins to be installed.

       <libs> will be passed to BundleUtilities and should be a list of any
       already installed plugins, libraries or executables to also be
       fixed-up.

       <dirs> will be passed to BundleUtilities and should contain and
       directories to be searched to find library dependencies.

       <plugins_dir> allows an custom plugins directory to be used.

       <request_qt_conf> will force a qt.conf file to be written even if not
       needed.

         INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>)

       Install (or copy) a resolved <plugin> to the default plugins directory
       (or <plugins_dir>) relative to <executable> and store the result in
       <installed_plugin_path_var>.

       If <copy> is set to TRUE then the plugins will be copied rather than
       installed.  This is to allow this module to be used at CMake time
       rather than install time.

       If <component> is set then anything installed will use this COMPONENT.

         INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>)

       Install (or copy) an unresolved <plugin> to the default plugins
       directory (or <plugins_dir>) relative to <executable> and store the
       result in <installed_plugin_path_var>.  See documentation of
       INSTALL_QT4_PLUGIN_PATH.

         INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>])

       Installs Qt plugins, writes a Qt configuration file (if needed) and
       fixes up a Qt4 executable using BundleUtilities so it is standalone
       and can be drag-and-drop copied to another machine as long as all of
       the system libraries are compatible.  The executable will be fixed-up
       at install time.  <component> is the COMPONENT used for bundle fixup
       and plugin installation.  See documentation of FIXUP_QT4_BUNDLE.

  ExternalProject
       Create custom targets to build projects in external trees

       The 'ExternalProject_Add' function creates a custom target to drive
       download, update/patch, configure, build, install and test steps of an
       external project:

         ExternalProject_Add(<name>    # Name for custom target
           [DEPENDS projects...]       # Targets on which the project depends
           [PREFIX dir]                # Root dir for entire project
           [LIST_SEPARATOR sep]        # Sep to be replaced by ; in cmd lines

           [GIT_REPOSITORY url]        # URL of git repo
           [GIT_TAG tag]               # Git branch name, commit id or tag
           [URL /.../src.tgz]          # Full path or URL of source
           [URL_MD5 md5]               # MD5 checksum of file at URL
           [TIMEOUT seconds]           # Time allowed for file download operations
          #--Update/Patch step----------
           [UPDATE_COMMAND cmd...]     # Source work-tree update command

           [SOURCE_DIR dir]            # Source dir to be used for build
           [CONFIGURE_COMMAND cmd...]  # Build tree configuration command
           [CMAKE_COMMAND /.../cmake]  # Specify alternative cmake executable
           [CMAKE_GENERATOR gen]       # Specify generator for native build
           [CMAKE_ARGS args...]        # Arguments to CMake command line
           [CMAKE_CACHE_ARGS args...]  # Initial cache arguments, of the form -Dvar:string=on
          #--Build step-----------------
           [BINARY_DIR dir]            # Specify build dir location
           [BUILD_COMMAND cmd...]      # Command to drive the native build
           [BUILD_IN_SOURCE 1]         # Use source dir for build dir
          #--Install step---------------
           [INSTALL_DIR dir]           # Installation prefix
           [INSTALL_COMMAND cmd...]    # Command to drive install after build
          #--Test step------------------
           [TEST_BEFORE_INSTALL 1]     # Add test step executed before install step
           [TEST_AFTER_INSTALL 1]      # Add test step executed after install step
           [TEST_COMMAND cmd...]       # Command to drive test
          #--Output logging-------------
           [LOG_DOWNLOAD 1]            # Wrap download in script to log output
           [LOG_UPDATE 1]              # Wrap update in script to log output
           [LOG_CONFIGURE 1]           # Wrap configure in script to log output
           [LOG_BUILD 1]               # Wrap build in script to log output
           [LOG_TEST 1]                # Wrap test in script to log output
           [LOG_INSTALL 1]             # Wrap install in script to log output
          #--Custom targets-------------
           [STEP_TARGETS st1 st2 ...]  # Generate custom targets for these steps
           )

       The *_DIR options specify directories for the project, with default
       directories computed as follows.  If the PREFIX option is given to
       ExternalProject_Add() or the EP_PREFIX directory property is set, then
       an external project is built and installed under the specified prefix:

          TMP_DIR      = <prefix>/tmp
          STAMP_DIR    = <prefix>/src/<name>-stamp
          DOWNLOAD_DIR = <prefix>/src
          SOURCE_DIR   = <prefix>/src/<name>
          BINARY_DIR   = <prefix>/src/<name>-build
          INSTALL_DIR  = <prefix>

       Otherwise, if the EP_BASE directory property is set then components of
       an external project are stored under the specified base:

          TMP_DIR      = <base>/tmp/<name>
          STAMP_DIR    = <base>/Stamp/<name>
          DOWNLOAD_DIR = <base>/Download/<name>
          SOURCE_DIR   = <base>/Source/<name>
          BINARY_DIR   = <base>/Build/<name>
          INSTALL_DIR  = <base>/Install/<name>

       If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is
       to set PREFIX to "<name>-prefix".  Relative paths are interpreted with
       respect to the build directory corresponding to the source directory
       in which ExternalProject_Add is invoked.

       If SOURCE_DIR is explicitly set to an existing directory the project
       will be built from it.  Otherwise a download step must be specified
       using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options.  The
       URL option may refer locally to a directory or source tarball, or
       refer to a remote tarball (e.g.  http://.../src.tgz).

       The 'ExternalProject_Add_Step' function adds a custom step to an
       external project:

         ExternalProject_Add_Step(<name> <step> # Names of project and custom step
           [COMMAND cmd...]        # Command line invoked by this step
           [COMMENT "text..."]     # Text printed when step executes
           [DEPENDEES steps...]    # Steps on which this step depends
           [DEPENDERS steps...]    # Steps that depend on this step
           [DEPENDS files...]      # Files on which this step depends
           [ALWAYS 1]              # No stamp file, step always runs
           [WORKING_DIRECTORY dir] # Working directory for command
           [LOG 1]                 # Wrap step in script to log output
           )

       The command line, comment, and working directory of every standard and
       custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>,
       <INSTALL_DIR>, and <TMP_DIR> with corresponding property values.

       The 'ExternalProject_Get_Property' function retrieves external project
       target properties:

         ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

       It stores property values in variables of the same name.  Property
       names correspond to the keyword argument names of
       'ExternalProject_Add'.

       The 'ExternalProject_Add_StepTargets' function generates custom
       targets for the steps listed:

         ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])

       

       If STEP_TARGETS is set then ExternalProject_Add_StepTargets is
       automatically called at the end of matching calls to
       ExternalProject_Add_Step.  Pass STEP_TARGETS explicitly to individual
       ExternalProject_Add calls, or implicitly to all ExternalProject_Add
       calls by setting the directory property EP_STEP_TARGETS.

       If STEP_TARGETS is not set, clients may still manually call
       ExternalProject_Add_StepTargets after calling ExternalProject_Add or
       ExternalProject_Add_Step.

       This functionality is provided to make it easy to drive the steps
       independently of each other by specifying targets on build command
       lines.  For example, you may be submitting to a sub-project based
       dashboard, where you want to drive the configure portion of the build,
       then submit to the dashboard, followed by the build portion, followed
       by tests.  If you invoke a custom target that depends on a step
       halfway through the step dependency chain, then all the previous steps
       will also run to ensure everything is up to date.

       For example, to drive configure, build and test steps independently
       for each ExternalProject_Add call in your project, write the following
       line prior to any ExternalProject_Add calls in your CMakeLists file:

          set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)


  FeatureSummary
       Macros for generating a summary of enabled/disabled features

       

       This module provides the macros feature_summary(),
       set_package_properties() and add_feature_info().  For compatibility it
       also still provides set_package_info(), set_feature_info(),
       print_enabled_features() and print_disabled_features().

       These macros can be used to generate a summary of enabled and disabled
       packages and/or feature for a build tree:

           -- The following OPTIONAL packages have been found:
           LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org>
              * Enables HTML-import in MyWordProcessor
              * Enables odt-export in MyWordProcessor
           PNG , A PNG image library. , <http://www.libpng.org/pub/png/>
              * Enables saving screenshots
           -- The following OPTIONAL packages have not been found:
           Lua51 , The Lua scripting language. , <http://www.lua.org>
              * Enables macros in MyWordProcessor
           Foo , Foo provides cool stuff.

       

       

           FEATURE_SUMMARY( [FILENAME <file>]
                            [APPEND]
                            [VAR <variable_name>]
                            [INCLUDE_QUIET_PACKAGES]
                            [FATAL_ON_MISSING_REQUIRED_PACKAGES]
                            [DESCRIPTION "Found packages:"]
                            WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
                                 | ENABLED_FEATURES | DISABLED_FEATURES]
                          )

       

       The FEATURE_SUMMARY() macro can be used to print information about
       enabled or disabled packages or features of a project.  By default,
       only the names of the features/packages will be printed and their
       required version when one was specified.  Use SET_PACKAGE_PROPERTIES()
       to add more useful information, like e.g.  a download URL for the
       respective package or their purpose in the project.

       The WHAT option is the only mandatory option.  Here you specify what
       information will be printed:

           ALL: print everything
           ENABLED_FEATURES: the list of all features which are enabled
           DISABLED_FEATURES: the list of all features which are disabled
           PACKAGES_FOUND: the list of all packages which have been found
           PACKAGES_NOT_FOUND: the list of all packages which have not been found
           OPTIONAL_PACKAGES_FOUND: only those packages which have been found which have the type OPTIONAL
           OPTIONAL_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type OPTIONAL
           RECOMMENDED_PACKAGES_FOUND: only those packages which have been found which have the type RECOMMENDED
           RECOMMENDED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RECOMMENDED
           REQUIRED_PACKAGES_FOUND: only those packages which have been found which have the type REQUIRED
           REQUIRED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type REQUIRED
           RUNTIME_PACKAGES_FOUND: only those packages which have been found which have the type RUNTIME
           RUNTIME_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RUNTIME

       

       If a FILENAME is given, the information is printed into this file.  If
       APPEND is used, it is appended to this file, otherwise the file is
       overwritten if it already existed.  If the VAR option is used, the
       information is "printed" into the specified variable.  If FILENAME is
       not used, the information is printed to the terminal.  Using the
       DESCRIPTION option a description or headline can be set which will be
       printed above the actual content.  If INCLUDE_QUIET_PACKAGES is given,
       packages which have been searched with find_package(...  QUIET) will
       also be listed.  By default they are skipped.  If
       FATAL_ON_MISSING_REQUIRED_PACKAGES is given, CMake will abort if a
       package which is marked as REQUIRED has not been found.

       Example 1, append everything to a file:

          feature_summary(WHAT ALL
                          FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

       

       Example 2, print the enabled features into the variable
       enabledFeaturesText, including QUIET packages:

          feature_summary(WHAT ENABLED_FEATURES
                          INCLUDE_QUIET_PACKAGES
                          DESCRIPTION "Enabled Features:"
                          VAR enabledFeaturesText)
          message(STATUS "${enabledFeaturesText}")

       

       

           SET_PACKAGE_PROPERTIES(<name> PROPERTIES [ URL <url> ]
                                                    [ DESCRIPTION <description> ]

                                 )

       

       Use this macro to set up information about the named package, which
       can then be displayed via FEATURE_SUMMARY().  This can be done either
       directly in the Find-module or in the project which uses the module
       after the FIND_PACKAGE() call.  The features for which information can
       be set are added automatically by the find_package() command.

       URL: this should be the homepage of the package, or something similar.
       Ideally this is set already directly in the Find-module.

       DESCRIPTION: A short description what that package is, at most one
       sentence.  Ideally this is set already directly in the Find-module.

       TYPE: What type of dependency has the using project on that package.
       Default is OPTIONAL.  In this case it is a package which can be used
       by the project when available at buildtime, but it also work without.
       RECOMMENDED is similar to OPTIONAL, i.e.  the project will build if
       the package is not present, but the functionality of the resulting
       binaries will be severly limited.  If a REQUIRED package is not
       available at buildtime, the project may not even build.  This can be
       combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument for
       feature_summary().  Last, a RUNTIME package is a package which is
       actually not used at all during the build, but which is required for
       actually running the resulting binaries.  So if such a package is
       missing, the project can still be built, but it may not work later on.
       If set_package_properties() is called multiple times for the same
       package with different TYPEs, the TYPE is only changed to higher TYPEs
       ( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are
       ignored.  The TYPE property is project-specific, so it cannot be set
       by the Find-module, but must be set in the project.

       PURPOSE: This describes which features this package enables in the
       project, i.e.  it tells the user what functionality he gets in the
       resulting binaries.  If set_package_properties() is called multiple
       times for a package, all PURPOSE properties are appended to a list of
       purposes of the package in the project.  As the TYPE property, also
       the PURPOSE property is project-specific, so it cannot be set by the
       Find-module, but must be set in the project.

       

       Example for setting the info for a package:

          find_package(LibXml2)
          set_package_properties(LibXml2 PROPERTIES DESCRIPTION "A XML processing library."
                                                    URL "http://xmlsoft.org/")

       

          set_package_properties(LibXml2 PROPERTIES TYPE RECOMMENDED
                                                    PURPOSE "Enables HTML-import in MyWordProcessor")
          ...
          set_package_properties(LibXml2 PROPERTIES TYPE OPTIONAL
                                                    PURPOSE "Enables odt-export in MyWordProcessor")

       

          find_package(DBUS)
          set_package_properties(DBUS PROPERTIES TYPE RUNTIME
                                                    PURPOSE "Necessary to disable the screensaver during a presentation" )

       

           ADD_FEATURE_INFO(<name> <enabled> <description>)

       Use this macro to add information about a feature with the given
       <name>.  <enabled> contains whether this feature is enabled or not,
       <description> is a text describing the feature.  The information can
       be displayed using feature_summary() for ENABLED_FEATURES and
       DISABLED_FEATURES respectively.

       Example for setting the info for a feature:

          option(WITH_FOO "Help for foo" ON)
          add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

       

       

       The following macros are provided for compatibility with previous
       CMake versions:

           SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] )

       Use this macro to set up information about the named package, which
       can then be displayed via FEATURE_SUMMARY().  This can be done either
       directly in the Find-module or in the project which uses the module
       after the FIND_PACKAGE() call.  The features for which information can
       be set are added automatically by the find_package() command.

           PRINT_ENABLED_FEATURES()

       Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION
       "Enabled features:")

           PRINT_DISABLED_FEATURES()

       Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION
       "Disabled features:")

           SET_FEATURE_INFO(<name> <description> [<url>] )

       Does the same as SET_PACKAGE_INFO(<name> <description> <url> )

            ALSA_LIBRARY     - the asound library
            ALSA_VERSION_STRING - the version of alsa found (since CMake 2.8.8)

       


  FindASPELL
       Try to find ASPELL

       Once done this will define

         ASPELL_FOUND - system has ASPELL
         ASPELL_EXECUTABLE - the ASPELL executable
         ASPELL_INCLUDE_DIR - the ASPELL include directory
         ASPELL_LIBRARIES - The libraries needed to use ASPELL
         ASPELL_DEFINITIONS - Compiler switches required for using ASPELL


  FindAVIFile
       Locate AVIFILE library and include paths

       AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
       i386 machines to use various AVI codecs.  Support is limited beyond
       Linux.  Windows provides native AVI support, and so doesn't need this
       library.  This module defines

         AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
         AVIFILE_LIBRARIES, the libraries to link against
         AVIFILE_DEFINITIONS, definitions to use when compiling
         AVIFILE_FOUND, If false, don't try to use AVIFILE


  FindArmadillo
       Find Armadillo

       Find the Armadillo C++ library

       Using Armadillo:

         find_package(Armadillo REQUIRED)
         include_directories(${ARMADILLO_INCLUDE_DIRS})
         add_executable(foo foo.cc)
         target_link_libraries(foo ${ARMADILLO_LIBRARIES})

       This module sets the following variables:

         ARMADILLO_FOUND - set to true if the library is found
         ARMADILLO_INCLUDE_DIRS - list of required include directories
         ARMADILLO_LIBRARIES - list of libraries to be linked
         ARMADILLO_VERSION_MAJOR - major version number
         ARMADILLO_VERSION_MINOR - minor version number
         ARMADILLO_VERSION_PATCH - patch version number
         ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4")
         ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")


  FindBISON
       Find bison executable and provides macros to generate custom build
       rules

       The module defines the following variables:

         BISON_EXECUTABLE - path to the bison program
         BISON_VERSION - version of bison
         BISON_FOUND - true if the program was found

       

       The minimum required version of bison can be specified using the
       standard CMake syntax, e.g.  find_package(BISON 2.1.3)

       If bison is found, the module defines the macros:

         BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
                     [COMPILE_FLAGS <string>])

       which will create a custom rule to generate a parser.  <YaccInput> is
       the path to a yacc file.  <CodeOutput> is the name of the source file
       generated by bison.  A header file is also be generated, and contains
       the token list.  If COMPILE_FLAGS option is specified, the next
       parameter is added in the bison command line.  if VERBOSE option is
       specified, <file> is created and contains verbose descriptions of the
       grammar and parser.  The macro defines a set of variables:

         BISON_${Name}_DEFINED - true is the macro ran successfully
         BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
         BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
         BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
         BISON_${Name}_OUTPUTS - The sources files generated by bison
         BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

       

         ====================================================================
         Example:

       

          find_package(BISON)
          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
         ====================================================================


  FindBLAS
       Find BLAS library

       This module finds an installed fortran library that implements the
       BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
       list of libraries searched for is taken from the autoconf macro file,
       acx_blas.m4 (distributed at
       http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

       This module sets the following variables:

         BLAS_FOUND - set to true if a library implementing the BLAS interface
           is found
         BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
           and -L).
         BLAS_LIBRARIES - uncached list of libraries (using full path name) to
           link against to use BLAS
         BLAS95_LIBRARIES - uncached list of libraries (using full path name)
           to link against to use BLAS95 interface
         BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
           is found
         BLA_STATIC  if set on this determines what kind of linkage we do (static)
         BLA_VENDOR  if set checks only the specified vendor, if not set checks
            all the possibilities
         BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

       C/CXX should be enabled to use Intel mkl

  FindBZip2
       Try to find BZip2

       Once done this will define

         BZIP2_FOUND - system has BZip2
         BZIP2_INCLUDE_DIR - the BZip2 include directory
         BZIP2_LIBRARIES - Link these to use BZip2
         BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
         BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8)


  FindBoost
       Try to find Boost include dirs and libraries

       Usage of this module as follows:

       NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below.  Due
       to Boost naming conventions and limitations in CMake this find module
       is NOT future safe with respect to Boost version numbers, and may
       break.

       == Using Header-Only libraries from within Boost: ==

          find_package( Boost 1.36.0 )
          if(Boost_FOUND)
             include_directories(${Boost_INCLUDE_DIRS})
             add_executable(foo foo.cc)
          endif()

       

       

       == Using actual libraries from within Boost: ==

          set(Boost_USE_STATIC_LIBS        ON)
          set(Boost_USE_MULTITHREADED      ON)
          set(Boost_USE_STATIC_RUNTIME    OFF)
          find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )

       

          if(Boost_FOUND)
             include_directories(${Boost_INCLUDE_DIRS})
             add_executable(foo foo.cc)
             target_link_libraries(foo ${Boost_LIBRARIES})
          endif()

       

       

       The components list needs to contain actual names of boost libraries
       only, such as "date_time" for "libboost_date_time".  If you're using
       parts of Boost that contain header files only (e.g.  foreach) you do
       not need to specify COMPONENTS.

       You should provide a minimum version number that should be used.  If
       you provide this version number and specify the REQUIRED attribute,
       this module will fail if it can't find the specified or a later
       version.  If you specify a version number this is automatically put
       into the considered list of version numbers and thus doesn't need to
       be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).

       NOTE for Visual Studio Users:

            Automatic linking is used on MSVC & Borland compilers by default when
            #including things in Boost.  It's important to note that setting
            Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
            should you need this feature.  Automatic linking typically uses static
            libraries with a few exceptions (Boost.Python is one).

       

            Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
            more details.  Adding a TARGET_LINK_LIBRARIES() as shown in the example
            above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
            gets set to OFF.  It is suggested you avoid automatic linking since it
            will make your application less portable.

       

       =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?)
       ============

       OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a
       list of boost version numbers that should be taken into account when
       searching for Boost.  Unfortunately boost puts the version number into
       the actual filename for the libraries, so this variable will certainly
       be needed in the future when new Boost versions are released.

       Currently this module searches for the following version numbers:
       1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
       1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0, 1.40,
       1.40.0, 1.41, 1.41.0, 1.42, 1.42.0, 1.43, 1.43.0, 1.44, 1.44.0, 1.45,
       1.45.0, 1.46, 1.46.0, 1.46.1, 1.47, 1.47.0, 1.48, 1.48.0, 1.49,
       1.49.0, 1.50, 1.50.0

       NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS
       you should add both 1.x and 1.x.0 as shown above.  Official Boost
       include directories omit the 3rd version number from include paths if
       it is 0 although not all binary Boost releases do so.

       set(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")

       ===================================== =============
       ========================

       Variables used by this module, they can change the default behaviour
       and need to be set before calling find_package:

          Boost_USE_MULTITHREADED      Can be set to OFF to use the non-multithreaded
                                       boost libraries.  If not specified, defaults
                                       to ON.

       

          Boost_USE_STATIC_LIBS        Can be set to ON to force the use of the static
                                       boost libraries. Defaults to OFF.

       

          Boost_NO_SYSTEM_PATHS        Set to TRUE to suppress searching in system
                                       paths (or other locations outside of BOOST_ROOT
                                       or BOOST_INCLUDEDIR).  Useful when specifying
                                       BOOST_ROOT. Defaults to OFF.
                                         [Since CMake 2.8.3]

       

          Boost_NO_BOOST_CMAKE         Do not do a find_package call in config mode
                                       before searching for a regular boost install.
                                       This will avoid finding boost-cmake installs.
                                       Defaults to OFF.
                                         [Since CMake 2.8.6]

       

          Boost_USE_STATIC_RUNTIME     If enabled, searches for boost libraries
                                       linked against a static C++ standard library
                                       ('s' ABI tag). This option should be set to
                                       ON or OFF because the default behavior
                                       if not specified is platform dependent
                                       for backwards compatibility.

                                       compiled against a special debug build of
                                       Python ('y' ABI tag). Defaults to OFF.

       Other Variables used by this module which you may want to set.

          Boost_ADDITIONAL_VERSIONS    A list of version numbers to use for searching
                                       the boost include directory.  Please see
                                       the documentation above regarding this
                                       annoying, but necessary variable :(

       

          Boost_DEBUG                  Set this to TRUE to enable debugging output
                                       of FindBoost.cmake if you are having problems.
                                       Please enable this before filing any bug

          Boost_DETAILED_FAILURE_MSG   FindBoost doesn't output detailed information
                                       about why it failed or how to fix the problem
                                       unless this is set to TRUE or the REQUIRED
                                       keyword is specified in find_package().

          Boost_COMPILER               Set this to the compiler suffix used by Boost
                                       (e.g. "-gcc43") if FindBoost has problems finding
                                       the proper Boost installation

       

          Boost_THREADAPI                When building boost.thread, sometimes the name of the
                                       library contains an additional "pthread" or "win32"
                                       string known as the threadapi.  This can happen when
                                       compiling against pthreads on Windows or win32 threads
                                       on Cygwin.  You may specify this variable and if set
                                       when FindBoost searches for the Boost threading library
                                       it will first try to match the threadapi you specify.
                                         For Example: libboost_thread_win32-mgw45-mt-1_43.a
                                       might be found if you specified "win32" here before
                                       falling back on libboost_thread-mgw45-mt-1_43.a.

          Boost_REALPATH               Resolves symbolic links for discovered boost libraries
                                       to assist with packaging.  For example, instead of
                                       Boost_SYSTEM_LIBRARY_RELEASE being resolved to
                                       "/usr/lib/libboost_system.so" it would be
                                       "/usr/lib/libboost_system.so.1.42.0" instead.
                                       This does not affect linking and should not be
                                       enabled unless the user needs this information.

  FindBullet
       Try to find the Bullet physics engine

       

         This module defines the following variables

       

         BULLET_FOUND - Was bullet found
         BULLET_INCLUDE_DIRS - the Bullet include directories
         BULLET_LIBRARIES - Link to this, by default it includes
                            all bullet components (Dynamics,
                            Collision, LinearMath, & SoftBody)

       

         This module accepts the following variables

       

         BULLET_ROOT - Can be set to bullet install path or Windows build path

       


  FindCABLE
       Find CABLE

       This module finds if CABLE is installed and determines where the
       include files and libraries are.  This code sets the following
       variables:

         CABLE             the path to the cable executable
         CABLE_TCL_LIBRARY the path to the Tcl wrapper library
         CABLE_INCLUDE_DIR the path to the include directory

       

       To build Tcl wrappers, you should add shared library and link it to
       ${CABLE_TCL_LIBRARY}.  You should also add ${CABLE_INCLUDE_DIR} as an
       include directory.

  FindCUDA
       Tools for building CUDA C files: libraries and build dependencies.

       This script locates the NVIDIA CUDA C tools.  It should work on linux,
       windows, and mac and should be reasonably up to date with CUDA C
       releases.

       This script makes use of the standard find_package arguments of
       <VERSION>, REQUIRED and QUIET.  CUDA_FOUND will report if an
       acceptable version of CUDA was found.

       The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if
       the prefix cannot be determined by the location of nvcc in the system
       path and REQUIRED is specified to find_package().  To use a different
       installed version of the toolkit set the environment variable
       CUDA_BIN_PATH before running cmake (e.g.
       CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
       /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.  If
       you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
       depend on the path will be relocated.

       It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
       platforms, or to use a cuda runtime not installed in the default
       location.  In newer versions of the toolkit the cuda library is
       included with the graphics driver- be sure that the driver version
       matches what is needed by the cuda runtime version.

       The following variables affect the behavior of the macros in the
       script (in alphebetical order).  Note that any of these flags can be
       changed multiple times in the same directory before calling
       CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX
       or CUDA_WRAP_SRCS.

         CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
         -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
            Note that making this different from the host code when generating object
            or C files from CUDA code just won't work, because size_t gets defined by
            nvcc in the generated source.  If you compile to PTX and then load the
            file yourself, you can mix bit sizes between device and host.

       

         CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
         -- Set to ON if you want the custom build rule to be attached to the source
            file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
            targets.

       

            This allows the user to build the target from the CUDA file; however, bad
            things can happen if the CUDA source file is added to multiple targets.
            When performing parallel builds it is possible for the custom build
            command to be run more than once and in parallel causing cryptic build
            errors.  VS runs the rules for every source file in the target, and a
            source can have only one rule no matter how many projects it is added to.
            When the rule is run from multiple targets race conditions can occur on
            the generated file.  Eventually everything will get built, but if the user
            is unaware of this behavior, there may be confusion.  It would be nice if
            this script could detect the reuse of source files across multiple targets
            and turn the option off for the user, but no good solution could be found.

       

         CUDA_BUILD_CUBIN (Default OFF)
         -- Set to ON to enable and extra compilation pass with the -cubin option in
            Device mode. The output is parsed and register, shared memory usage is
            printed during build.

       

         CUDA_BUILD_EMULATION (Default OFF for device mode)
         -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
            when CUDA_BUILD_EMULATION is TRUE.

       

         CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
         -- Set to the path you wish to have the generated files placed.  If it is
            blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
            Intermediate files will always be placed in
            CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

       

         CUDA_HOST_COMPILATION_CPP (Default ON)
         -- Set to OFF for C compilation of host code.

       

         CUDA_NVCC_FLAGS
         CUDA_NVCC_FLAGS_<CONFIG>
         -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
            semi-colon delimited (e.g. --compiler-options;-Wall)

       

         CUDA_PROPAGATE_HOST_FLAGS (Default ON)
         -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
            dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
            host compiler through nvcc's -Xcompiler flag.  This helps make the
            generated host code match the rest of the system better.  Sometimes
            certain flags give nvcc problems, and this will help you turn the flag
            propagation off.  This does not affect the flags supplied directly to nvcc
            via CUDA_NVCC_FLAGS or through the OPTION flags specified through
            CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
            shared library compilation are not affected by this flag.

       

         CUDA_VERBOSE_BUILD (Default OFF)
         -- Set to ON to see all the commands used when building the CUDA file.  When
            using a Makefile generator the value defaults to VERBOSE (run make
            VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
            always print the output.

       

       The script creates the following macros (in alphebetical order):

         CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
         -- Adds the cufft library to the target (can be any target).  Handles whether
            you are in emulation mode or not.

       

         CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
         -- Adds the cublas library to the target (can be any target).  Handles
            whether you are in emulation mode or not.

       

         CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
                              [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
         -- Creates an executable "cuda_target" which is made up of the files
            specified.  All of the non CUDA C files are compiled using the standard
            build rules specified by CMAKE and the cuda files are compiled to object
            files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
            added automatically to include_directories().  Some standard CMake target
            calls can be used on the target after calling this macro
            (e.g. set_target_properties and target_link_libraries), but setting
            properties that adjust compilation flags will not affect code compiled by
            nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
            CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

       

         CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
                           [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
         -- Same as CUDA_ADD_EXECUTABLE except that a library is created.

       

         CUDA_BUILD_CLEAN_TARGET()
         -- Creates a convience target that deletes all the dependency files
            generated.  You should make clean after running this target to ensure the
            dependency files get regenerated.

       

         CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
                       [OPTIONS ...] )
         -- Returns a list of generated files from the input source files to be used
            with ADD_LIBRARY or ADD_EXECUTABLE.

       

         CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
         -- Returns a list of PTX files generated from the input source files.

       

         CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
         -- Sets the directories that should be passed to nvcc
            (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
            files.

       

         CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
                          [STATIC | SHARED | MODULE] [OPTIONS ...] )
         -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
            CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
            function under the hood.

       

            Given the list of files (file0 file1 ... fileN) this macro generates
            custom commands that generate either PTX or linkable objects (use "PTX" or
            "OBJ" for the format argument to switch).  Files that don't end with .cu
            or have the HEADER_FILE_ONLY property are ignored.

       

            The arguments passed in after OPTIONS are extra command line options to
            give to nvcc.  You can also specify per configuration options by
            specifying the name of the configuration followed by the options.  General
            options must preceed configuration specific options.  Not all
            configurations need to be specified, only the ones provided will be used.

       

               OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
               DEBUG -g
               RELEASE --use_fast_math
               RELWITHDEBINFO --use_fast_math;-g
               MINSIZEREL --use_fast_math

       

            For certain configurations (namely VS generating object files with
            CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
            be produced for the given cuda file.  This is because when you add the
            cuda file to Visual Studio it knows that this file produces an object file
            and will link in the resulting object file automatically.

       

            This script will also generate a separate cmake script that is used at
            build time to invoke nvcc.  This is for several reasons.

       

              1. nvcc can return negative numbers as return values which confuses
              Visual Studio into thinking that the command succeeded.  The script now
              checks the error codes and produces errors when there was a problem.

       

              2. nvcc has been known to not delete incomplete results when it
              encounters problems.  This confuses build systems into thinking the
              target was generated when in fact an unusable file exists.  The script
              now deletes the output files if there was an error.

       

              3. By putting all the options that affect the build into a file and then
              make the build rule dependent on the file, the output files will be
              regenerated when the options change.

       

            This script also looks at optional arguments STATIC, SHARED, or MODULE to
            determine when to target the object compilation for a shared library.
            BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
            CUDA_ADD_LIBRARY.  On some systems special flags are added for building
            objects intended for shared libraries.  A preprocessor macro,
            <target_name>_EXPORTS is defined when a shared library compilation is
            detected.

       

            Flags passed into add_definitions with -D or /D are passed along to nvcc.

       

       The script defines the following variables:

         CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
         CUDA_VERSION_MINOR    -- The minor version.
         CUDA_VERSION
         CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

       

         CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
         CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
                                  SDK.  This script will not directly support finding
                                  specific libraries or headers, as that isn't
                                  supported by NVIDIA.  If you want to change
                                  libraries when the path changes see the
                                  FindCUDA.cmake script for an example of how to clear
                                  these variables.  There are also examples of how to
                                  use the CUDA_SDK_ROOT_DIR to locate headers or
                                  libraries, if you so choose (at your own risk).
         CUDA_INCLUDE_DIRS     -- Include directory for cuda headers.  Added automatically
                                  for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
         CUDA_LIBRARIES        -- Cuda RT library.

                     2. Create an executable and test called unittest_foo.
                      
             #=============
             Example foo_test.h:

       

                 #include <cxxtest/TestSuite.h>
                 
                 class MyTestSuite : public CxxTest::TestSuite 
                 {
                 public:
                    void testAddition( void )
                    {
                       TS_ASSERT( 1 + 1 > 1 );
                       TS_ASSERT_EQUALS( 1 + 1, 2 );
                    }
                 };

       


  FindCygwin

  FindDCMTK
       find DCMTK libraries and applications

       


  FindDart
       Find DART

       This module looks for the dart testing software and sets DART_ROOT to

  FindDevIL
        

       This module locates the developer's image library.
       http://openil.sourceforge.net/

       This module sets: IL_LIBRARIES the name of the IL library.  These
       include the full path to the core DevIL library.  This one has to be
       linked into the application.  ILU_LIBRARIES the name of the ILU
       library.  Again, the full path.  This library is for filters and
       effects, not actual loading.  It doesn't have to be linked if the
       functionality it provides is not used.  ILUT_LIBRARIES the name of the
       ILUT library.  Full path.  This part of the library interfaces with
       OpenGL.  It is not strictly needed in applications.  IL_INCLUDE_DIR
       where to find the il.h, ilu.h and ilut.h files.  IL_FOUND this is set
       to TRUE if all the above variables were set.  This will be set to
       false if ILU or ILUT are not found, even if they are not needed.  In
       most systems, if one library is found all the others are as well.
       That's the way the DevIL developers release it.

  FindDoxygen
       This module looks for Doxygen and the path to Graphviz's dot

       Doxygen is a documentation generation tool.  Please see
       http://www.doxygen.org

       This module accepts the following optional variables:

          DOXYGEN_SKIP_DOT       = If true this module will skip trying to find Dot
                                   (an optional component often used by Doxygen)

       

       This modules defines the following variables:

          DOXYGEN_EXECUTABLE     = The path to the doxygen command.
          DOXYGEN_FOUND          = Was Doxygen found or not?
          DOXYGEN_VERSION        = The version reported by doxygen --version

       

          DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
          DOXYGEN_DOT_FOUND      = Was Dot found or not?
          DOXYGEN_DOT_PATH       = The path to dot not including the executable

       

       


  FindEXPAT
       Find expat

       Find the native EXPAT headers and libraries.

         EXPAT_INCLUDE_DIRS - where to find expat.h, etc.
         EXPAT_LIBRARIES    - List of libraries when using expat.
         EXPAT_FOUND        - True if expat found.


  FindFLEX
       Find flex executable and provides a macro to generate custom build
       rules

       

       The module defines the following variables:

         FLEX_FOUND - true is flex executable is found
         FLEX_EXECUTABLE - the path to the flex executable
         FLEX_VERSION - the version of flex
         FLEX_LIBRARIES - The flex libraries
         FLEX_INCLUDE_DIRS - The path to the flex headers

       

       The minimum required version of flex can be specified using the
       standard syntax, e.g.  FIND_PACKAGE(FLEX 2.5.13)

       

       If flex is found on the system, the module provides the macro:

         FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

       which creates a custom command to generate the <FlexOutput> file from
       the <FlexInput> file.  If COMPILE_FLAGS option is specified, the next
       parameter is added to the flex command line.  Name is an alias used to
       get details of this custom command.  Indeed the macro defines the
       following variables:

         FLEX_${Name}_DEFINED - true is the macro ran successfully
         FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
         alias for FlexOutput
         FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

       

       Flex scanners oftenly use tokens defined by Bison: the code generated
       by Flex depends of the header generated by Bison.  This module also
       defines a macro:

         ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

       which adds the required dependency between a scanner and a parser
       where <FlexTarget> and <BisonTarget> are the first parameters of
       respectively FLEX_TARGET and BISON_TARGET macros.

         ====================================================================
         Example:

       

          find_package(BISON)
          find_package(FLEX)

       

          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          FLEX_TARGET(MyScanner lexer.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
          ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

       

          include_directories(${CMAKE_CURRENT_BINARY_DIR})
          add_executable(Foo
             Foo.cc
             ${BISON_MyParser_OUTPUTS}
             ${FLEX_MyScanner_OUTPUTS}
          )
         ====================================================================

       Also defines the library variables below as normal variables.  These
       contain debug/optimized keywords when a debugging library is found.

          GTEST_BOTH_LIBRARIES - Both libgtest & libgtest-main
          GTEST_LIBRARIES - libgtest
          GTEST_MAIN_LIBRARIES - libgtest-main

       

       Accepts the following variables as input:

          GTEST_ROOT - (as a CMake or environment variable)
                       The root directory of the gtest install prefix

       

          GTEST_MSVC_SEARCH - If compiling with MSVC, this variable can be set to
                              "MD" or "MT" to enable searching a GTest build tree
                              (defaults: "MD")

       

       Example Usage:

           enable_testing()
           find_package(GTest REQUIRED)
           include_directories(${GTEST_INCLUDE_DIRS})

       

           add_executable(foo foo.cc)
           target_link_libraries(foo ${GTEST_BOTH_LIBRARIES})

       

           add_test(AllTestsInFoo foo)

       

       

       If you would like each Google test to show up in CTest as a test you
       may use the following macro.  NOTE: It will slow down your tests by
       running an executable for each test and test fixture.  You will also
       have to rerun CMake after adding or removing tests or test fixtures.

       GTEST_ADD_TESTS(executable extra_args ARGN)

           executable = The path to the test executable
           extra_args = Pass a list of extra arguments to be passed to
                        executable enclosed in quotes (or "" for none)
           ARGN =       A list of source files to search for tests & test
                        fixtures.

       

         Example:
            set(FooTestArgs --foo 1 --bar 2)
            add_executable(FooTest FooUnitTest.cc)
            GTEST_ADD_TESTS(FooTest "${FooTestArgs}" FooUnitTest.cc)


  FindGettext
       Find GNU gettext tools

       This module looks for the GNU gettext tools.  This module defines the
       following values:

         GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool.
         GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
         GETTEXT_FOUND: True if gettext has been found.
         GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)

       

       Additionally it provides the following macros:
       GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ...  fileN )

           This will create a target "translations" which will convert the
           given input po files into the binary output mo file. If the
           ALL option is used, the translations will also be created when
           building the default target.

       GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <destdir>]
       LANGUAGES <lang1> <lang2> ...  )

            Process the given pot file to mo files.
            If INSTALL_DESTINATION is given then automatically install rules will be created,
            the language subdirectory will be taken into account (by default use share/locale/).
            If ALL is specified, the pot file is processed when building the all traget.
            It creates a custom target "potfile".

       GETTEXT_PROCESS_PO_FILES( <lang> [ALL] [INSTALL_DESTINATION <dir>]
       PO_FILES <po1> <po2> ...  )

            Process the given po files to mo files for the given language.
            If INSTALL_DESTINATION is given then automatically install rules will be created,
            the language subdirectory will be taken into account (by default use share/locale/).
            If ALL is specified, the po files are processed when building the all traget.
            It creates a custom target "pofiles".


  FindGit
        

       The module defines the following variables:

          GIT_EXECUTABLE - path to git command line client
          GIT_FOUND - true if the command line client was found
          GIT_VERSION_STRING - the version of git found (since CMake 2.8.8)

       Example usage:

          find_package(Git)
          if(GIT_FOUND)
            message("git found: ${GIT_EXECUTABLE}")
          endif()


  FindGnuTLS
       Try to find the GNU Transport Layer Security library (gnutls)

       

       Once done this will define

         GNUTLS_FOUND - System has gnutls
         GNUTLS_INCLUDE_DIR - The gnutls include directory
         GNUTLS_LIBRARIES - The libraries needed to use gnutls
         GNUTLS_DEFINITIONS - Compiler switches required for using gnutls


  FindGnuplot
       this module looks for gnuplot

       

       Once done this will define

         GNUPLOT_FOUND - system has Gnuplot
         GNUPLOT_EXECUTABLE - the Gnuplot executable
         GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)

       

       GNUPLOT_VERSION_STRING will not work for old versions like 3.7.1.

  FindHDF5
       Find HDF5, a library for reading and writing self describing array
       data.

       

       This module invokes the HDF5 wrapper compiler that should be installed
       alongside HDF5.  Depending upon the HDF5 Configuration, the wrapper
       compiler is called either h5cc or h5pcc.  If this succeeds, the module
       will then call the compiler with the -show argument to see what flags
       are used when compiling an HDF5 client application.

       The module will optionally accept the COMPONENTS argument.  If no
       COMPONENTS are specified, then the find module will default to finding
       only the HDF5 C library.  If one or more COMPONENTS are specified, the
       module will attempt to find the language bindings for the specified
       components.  The only valid components are C, CXX, Fortran, HL, and
       Fortran_HL.  If the COMPONENTS argument is not given, the module will
       attempt to find only the C bindings.

       On UNIX systems, this module will read the variable
       HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
       static link to a dynamic link for HDF5 and all of it's dependencies.
       To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
       variable is set before the call to find_package.

       To provide the module with a hint about where to find your HDF5
       installation, you can set the environment variable HDF5_ROOT.  The
       Find module will then look in this path when searching for HDF5
       executables, paths, and libraries.

       In addition to finding the includes and libraries required to compile
       an HDF5 client application, this module also makes an effort to find
       tools that come with the HDF5 distribution that may be useful for
       regression testing.

       This module will define the following variables:

         HDF5_INCLUDE_DIRS - Location of the hdf5 includes
         HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
         HDF5_DEFINITIONS - Required compiler definitions for HDF5
         HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.
         HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
         HDF5_Fortran_LIBRARIES - Required libraries for the HDF5 Fortran bindings
         HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API
         HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
                                     bindings.
         HDF5_LIBRARIES - Required libraries for all requested bindings
         HDF5_FOUND - true if HDF5 was found on the system
         HDF5_LIBRARY_DIRS - the full set of library directories
         HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
         HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
         HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
         HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler
         HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool


  FindHSPELL
       Try to find Hspell

       Once done this will define

         HSPELL_FOUND - system has Hspell
         HSPELL_INCLUDE_DIR - the Hspell include directory
         HSPELL_LIBRARIES - The libraries needed to use Hspell
         HSPELL_DEFINITIONS - Compiler switches required for using Hspell

         HSPELL_MAJOR_VERSION  - the major version of Hspell
         HSPELL_MINOR_VERSION  - The minor version of Hspell


  FindHTMLHelp
       This module looks for Microsoft HTML Help Compiler

       It defines:

          HTML_HELP_COMPILER     : full path to the Compiler (hhc.exe)
          HTML_HELP_INCLUDE_PATH : include path to the API (htmlhelp.h)
          HTML_HELP_LIBRARY      : full path to the library (htmlhelp.lib)

       


  FindITK
       Find an ITK installation or build tree.

  FindImageMagick
       Find the ImageMagick binary suite.

       This module will search for a set of ImageMagick tools specified as
       components in the FIND_PACKAGE call.  Typical components include, but
       are not limited to (future versions of ImageMagick might have
       additional components not listed here):

         animate
         compare
         composite
         conjure
         convert
         display
         identify
         import
         mogrify
         montage
         stream

       

       If no component is specified in the FIND_PACKAGE call, then it only
       searches for the ImageMagick executable directory.  This code defines
       the following variables:

         ImageMagick_FOUND                  - TRUE if all components are found.
         ImageMagick_EXECUTABLE_DIR         - Full path to executables directory.

                                              (since CMake 2.8.8)

       

       ImageMagick_VERSION_STRING will not work for old versions like 5.2.3.

       There are also components for the following ImageMagick APIs:

         Magick++
         MagickWand
         MagickCore

       

       For these components the following variables are set:

         ImageMagick_FOUND                    - TRUE if all components are found.
         ImageMagick_INCLUDE_DIRS             - Full paths to all include dirs.
         ImageMagick_LIBRARIES                - Full paths to all libraries.

         ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs.
         ImageMagick_<component>_LIBRARIES    - Full path to <component> libraries.

       

       Example Usages:

         FIND_PACKAGE(ImageMagick)

         FIND_PACKAGE(ImageMagick COMPONENTS Magick++ convert)

       

       Note that the standard FIND_PACKAGE features are supported (i.e.,
       QUIET, REQUIRED, etc.).

  FindJNI
       Find JNI java libraries.

       This module finds if Java is installed and determines where the
       include files and libraries are.  It also determines what the name of

       It also adds the following macros (from KDE3Macros.cmake) SRCS_VAR is
       always the variable which contains the list of source files for your
       application or library.

       KDE3_AUTOMOC(file1 ...  fileN)

           Call this if you want to have automatic moc file handling.
           This means if you include "foo.moc" in the source file foo.cpp
           a moc file for the header foo.h will be created automatically.
           You can set the property SKIP_AUTOMAKE using SET_SOURCE_FILES_PROPERTIES()
           to exclude some files in the list from being processed.

       

       KDE3_ADD_MOC_FILES(SRCS_VAR file1 ...  fileN )

           If you don't use the KDE3_AUTOMOC() macro, for the files
           listed here moc files will be created (named "foo.moc.cpp")

       

       KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ...  headerN.h )

           Use this to generate DCOP skeletions from the listed headers.

       

       KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ...  headerN.h )

            Use this to generate DCOP stubs from the listed headers.

       

       KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ...  fileN.ui )

           Use this to add the Qt designer ui files to your application/library.

       

       KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ...  fileN.kcfgc )

           Use this to add KDE kconfig compiler files to your application/library.

       

       KDE3_INSTALL_LIBTOOL_FILE(target)

           This will create and install a simple libtool file for the given target.

       

       KDE3_ADD_EXECUTABLE(name file1 ...  fileN )

           Currently identical to ADD_EXECUTABLE(), may provide some advanced features in the future.

       

       KDE3_ADD_KPART(name [WITH_PREFIX] file1 ...  fileN )

           Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
           If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
           It creates and installs an appropriate libtool la-file.

       

       KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ...  fileN )

           Create a KDE application in the form of a module loadable via kdeinit.
           A library named kdeinit_<name> will be created and a small executable which links to it.

       

       The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no
       longer supported.

         LUA_INCLUDE_DIR, where to find lua.h and lualib.h (and probably lauxlib.h)

       

       Note that the expected include convention is

         #include "lua.h"

       and not

         #include <lua/lua.h>

         MPEG2_vo_LIBRARY, where to find the vo library.


  FindMPI
       Find a Message Passing Interface (MPI) implementation

       The Message Passing Interface (MPI) is a library used to write
       high-performance distributed-memory parallel applications, and is
       typically deployed on a cluster.  MPI is a standard interface (defined
       by the MPI forum) for which many implementations are available.  All
       of them have somewhat different include paths, libraries to link
       against, etc., and this module tries to smooth out those differences.

       === Variables ===

       This module will set the following variables per language in your
       project, where <lang> is one of C, CXX, or Fortran:

          MPI_<lang>_FOUND           TRUE if FindMPI found MPI flags for <lang>
          MPI_<lang>_COMPILER        MPI Compiler wrapper for <lang>
          MPI_<lang>_COMPILE_FLAGS   Compilation flags for MPI programs
          MPI_<lang>_INCLUDE_PATH    Include path(s) for MPI header
          MPI_<lang>_LINK_FLAGS      Linking flags for MPI programs
          MPI_<lang>_LIBRARIES       All libraries to link MPI programs against

       Additionally, FindMPI sets the following variables for running MPI
       programs from the command line:

          MPIEXEC                    Executable for running MPI programs
          MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving
                                     it the number of processors to run on
          MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly
                                     before the executable to run.
          MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after other flags

       === Usage ===

       To use this module, simply call FindMPI from a CMakeLists.txt file, or
       run find_package(MPI), then run CMake.  If you are happy with the
       auto- detected configuration for your language, then you're done.  If
       not, you have two options:

          1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
             choice and reconfigure.  FindMPI will attempt to determine all the
             necessary variables using THAT compiler's compile and link flags.
          2. If this fails, or if your MPI implementation does not come with
             a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
             MPI_<lang>_INCLUDE_PATH.  You may also set any other variables
             listed above, but these two are required.  This will circumvent
             autodetection entirely.

       When configuration is successful, MPI_<lang>_COMPILER will be set to
       the compiler wrapper for <lang>, if it was found.  MPI_<lang>_FOUND
       and other variables above will be set if any MPI implementation was
       found for <lang>, regardless of whether a compiler was found.

       When using MPIEXEC to execute MPI applications, you should typically
       use all of the MPIEXEC flags as follows:

          ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
            ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS

       where PROCS is the number of processors on which to execute the
       program, EXECUTABLE is the MPI program, and ARGS are the arguments to
       pass to the MPI program.

       === Backward Compatibility ===

       For backward compatibility with older versions of FindMPI, these
       variables are set, but deprecated:

          MPI_FOUND           MPI_COMPILER        MPI_LIBRARY
          MPI_COMPILE_FLAGS   MPI_INCLUDE_PATH    MPI_EXTRA_LIBRARY
          MPI_LINK_FLAGS      MPI_LIBRARIES

       In new projects, please use the MPI_<lang>_XXX equivalents.

  FindMatlab
       this module looks for Matlab

         MATLAB_ENG_LIBRARY: path to libeng.lib


  FindMotif
       Try to find Motif (or lesstif)

       Once done this will define:

         MOTIF_FOUND        - system has MOTIF
         MOTIF_INCLUDE_DIR  - include paths to use Motif
         MOTIF_LIBRARIES    - Link these to use Motif


  FindOpenAL
        

       Locate OpenAL This module defines OPENAL_LIBRARY OPENAL_FOUND, if
       false, do not try to link to OpenAL OPENAL_INCLUDE_DIR, where to find
       the headers

       $OPENALDIR is an environment variable that would correspond to the
       ./configure --prefix=$OPENALDIR used in building OpenAL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module.

  FindOpenGL
       Try to find OpenGL

       Once done this will define

         
         OPENGL_FOUND        - system has OpenGL
         OPENGL_XMESA_FOUND  - system has XMESA
         OPENGL_GLU_FOUND    - system has GLU
         OPENGL_INCLUDE_DIR  - the GL include directory
         OPENGL_LIBRARIES    - Link these to use OpenGL and GLU
          

       If you want to use just GL you can use these values

         OPENGL_gl_LIBRARY   - Path to OpenGL Library
         OPENGL_glu_LIBRARY  - Path to GLU Library
         

       On OSX default to using the framework version of opengl People will
       have to change the cache values of OPENGL_glu_LIBRARY and
       OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

  FindOpenMP
       Finds OpenMP support

       This module can be used to detect OpenMP support in a compiler.  If
       the compiler supports OpenMP, the flags required to compile with
       openmp support are set.

       The following variables are set:

          OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
          OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support
          OPENMP_FOUND - true if openmp is detected

       

       Supported compilers can be found at
       http://openmp.org/wp/openmp-compilers/

  FindOpenSSL
       Try to find the OpenSSL encryption library

       Once done this will define

         OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL

       

       Read-Only variables:

         OPENSSL_FOUND - system has the OpenSSL library
         OPENSSL_INCLUDE_DIR - the OpenSSL include directory
         OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
         OPENSSL_VERSION - This is set to $major.$minor.$revision$path (eg. 0.9.8s)


  FindOpenSceneGraph
       Find OpenSceneGraph

       This module searches for the OpenSceneGraph core "osg" library as well
       as OpenThreads, and whatever additional COMPONENTS (nodekits) that you
       specify.

           See http://www.openscenegraph.org

       

       NOTE: To use this module effectively you must either require CMake >=
       2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place
       FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and
       Find<etc>.cmake files into your CMAKE_MODULE_PATH.

       ==================================

       This module accepts the following variables (note mixed case)

           OpenSceneGraph_DEBUG - Enable debugging output

       

           OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced 
                                             automatically

       

       The following environment variables are also respected for finding the
       OSG and it's various components.  CMAKE_PREFIX_PATH can also be used
       for this (see find_library() CMake documentation).

           <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
           OSG_DIR
           OSGDIR
           OSG_ROOT

       

       This module defines the following output variables:

           OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

       

           OPENSCENEGRAPH_VERSION - The version of the OSG which was found

       

           OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

       

           OPENSCENEGRAPH_LIBRARIES - The OSG libraries

       

       ================================== Example Usage:

         find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
             # libOpenThreads & libosg automatically searched
         include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

       

         add_executable(foo foo.cc)
         target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

       


  FindOpenThreads
        

       OpenThreads is a C++ based threading library.  Its largest userbase
       seems to OpenSceneGraph so you might notice I accept OSGDIR as an
       environment path.  I consider this part of the Findosg* suite used to
       find OpenSceneGraph components.  Each component is separate and you
       must opt in to each module.

       Locate OpenThreads This module defines OPENTHREADS_LIBRARY
       OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
       OPENTHREADS_INCLUDE_DIR, where to find the headers

       $OPENTHREADS_DIR is an environment variable that would correspond to
       the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

       Created by Eric Wing.

  FindPHP4
       Find PHP4

       This module finds if PHP4 is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PHP4_INCLUDE_PATH       = path to where php.h can be found
         PHP4_EXECUTABLE         = full path to the php4 binary

       


  FindPNG
       Find the native PNG includes and library

       

       This module searches libpng, the library for working with PNG images.

       It defines the following variables

         PNG_INCLUDE_DIRS, where to find png.h, etc.
         PNG_LIBRARIES, the libraries to link against to use PNG.
         PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
         PNG_FOUND, If false, do not try to use PNG.
         PNG_VERSION_STRING - the version of the PNG library found (since CMake 2.8.8)

       Also defined, but not for general use are

         PNG_LIBRARY, where to find the PNG library.

       For backward compatiblity the variable PNG_INCLUDE_DIR is also set.
       It has the same value as PNG_INCLUDE_DIRS.

       Since PNG depends on the ZLib compression library, none of the above
       will be defined unless ZLib can be found.

  FindPackageHandleStandardArgs
        

       FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ...  )

       This function is intended to be used in FindXXX.cmake modules files.
       It handles the REQUIRED, QUIET and version-related arguments to
       FIND_PACKAGE().  It also sets the <UPPERCASED_NAME>_FOUND variable.
       The package is considered found if all variables <var1>...  listed
       contain valid results, e.g.  valid filepaths.

       There are two modes of this function.  The first argument in both
       modes is the name of the Find-module where it is called (in original
       casing).

       The first simple mode looks like this:

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )

       If the variables <var1> to <varN> are all valid, then
       <UPPERCASED_NAME>_FOUND will be set to TRUE.  If DEFAULT_MSG is given
       as second argument, then the function will generate itself useful
       success and error messages.  You can also supply a custom error
       message for the failure case.  This is not recommended.

       The second mode is more powerful and also supports version checking:

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [REQUIRED_VARS <var1>...<varN>]
                                                  [VERSION_VAR   <versionvar>]
                                                  [HANDLE_COMPONENTS]
                                                  [CONFIG_MODE]
                                                  [FAIL_MESSAGE "Custom failure message"] )

       

       As above, if <var1> through <varN> are all valid,
       <UPPERCASED_NAME>_FOUND will be set to TRUE.  After REQUIRED_VARS the
       variables which are required for this package are listed.  Following
       VERSION_VAR the name of the variable can be specified which holds the
       version of the package which has been found.  If this is done, this
       version will be checked against the (potentially) specified required
       version used in the find_package() call.  The EXACT keyword is also
       handled.  The default messages include information about the required
       version and the version which has been actually found, both if the
       version is ok or not.  If the package supports components, use the
       HANDLE_COMPONENTS option to enable handling them.  In this case,
       find_package_handle_standard_args() will report which components have
       been found and which are missing, and the <NAME>_FOUND variable will
       be set to FALSE if any of the required components (i.e.  not the ones
       listed after OPTIONAL_COMPONENTS) are missing.  Use the option
       CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
       find_package(...  NO_MODULE) call.  In this case VERSION_VAR will be
       set to <NAME>_VERSION and the macro will automatically check whether
       the Config module was found.  Via FAIL_MESSAGE a custom failure
       message can be specified, if this is not used, the default message
       will be displayed.

       Example for mode 1:

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2  DEFAULT_MSG  LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

       

       LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
       LIBXML2_INCLUDE_DIR are valid.  Then also LIBXML2_FOUND is set to
       TRUE.  If it is not found and REQUIRED was used, it fails with
       FATAL_ERROR, independent whether QUIET was used or not.  If it is
       found, success will be reported, including the content of <var1>.  On
       repeated Cmake runs, the same message won't be printed again.

       Example for mode 2:

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(BISON  REQUIRED_VARS BISON_EXECUTABLE
                                                    VERSION_VAR BISON_VERSION)

       In this case, BISON is considered to be found if the variable(s)
       listed after REQUIRED_VAR are all valid, i.e.  BISON_EXECUTABLE in
       this case.  Also the version of BISON will be checked by using the
       version contained in BISON_VERSION.  Since no FAIL_MESSAGE is given,
       the default messages will be printed.

       Another example for mode 2:

           FIND_PACKAGE(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
           FIND_PACKAGE_HANDLE_STANDARD_ARGS(Automoc4  CONFIG_MODE)

       In this case, FindAutmoc4.cmake wraps a call to FIND_PACKAGE(Automoc4
       NO_MODULE) and adds an additional search directory for automoc4.  The
       following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
       success/error message.

  FindPackageMessage
        

       FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

       This macro is intended to be used in FindXXX.cmake modules files.  It
       will print a message once for each unique find result.  This is useful
       for telling the user where a package was found.  The first argument
       specifies the name (XXX) of the package.  The second argument
       specifies the message to display.  The third argument lists details
       about the find result so that if they change the message will be
       displayed again.  The macro also obeys the QUIET argument to the
       find_package command.

       Example:

         IF(X11_FOUND)
           FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
             "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
         ELSE(X11_FOUND)
          ...
         ENDIF(X11_FOUND)


  FindPerl
       Find perl

       this module looks for Perl

         PERL_EXECUTABLE     - the full path to perl
         PERL_FOUND          - If false, don't attempt to use perl.
         PERL_VERSION_STRING - version of perl found (since CMake 2.8.8)


  FindPerlLibs
       Find Perl libraries

       This module finds if PERL is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PERLLIBS_FOUND    = True if perl.h & libperl were found
         PERL_INCLUDE_PATH = path to where perl.h is found
         PERL_LIBRARY      = path to libperl
         PERL_EXECUTABLE   = full path to the perl binary

       

       The minimum required version of Perl can be specified using the
       standard syntax, e.g.  FIND_PACKAGE(PerlLibs 6.0)

         The following variables are also available if needed
         (introduced after CMake 2.6.4)

       

         PERL_SITESEARCH    = path to the sitesearch install dir
         PERL_SITELIB       = path to the sitelib install directory
         PERL_VENDORARCH    = path to the vendor arch install directory
         PERL_VENDORLIB     = path to the vendor lib install directory
         PERL_ARCHLIB       = path to the arch lib install directory
         PERL_PRIVLIB       = path to the priv lib install directory
         PERL_EXTRA_C_FLAGS = Compilation flags used to build perl

       


  FindPhysFS
        

       Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of
       the library to link against PHYSFS_FOUND, if false, do not try to link
       to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

       $PHYSFSDIR is an environment variable that would correspond to the
       ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

       Created by Eric Wing.

  FindPike
       Find Pike

       This module finds if PIKE is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PIKE_INCLUDE_PATH       = path to where program.h is found
         PIKE_EXECUTABLE         = full path to the pike binary

       


  FindPkgConfig
       a pkg-config module for CMake

       

       Usage:

          pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
            checks for all the given modules

       

          pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
            checks for given modules and uses the first working one

       

       When the 'REQUIRED' argument was set, macros will fail with an error
       when module(s) could not be found

       When the 'QUIET' argument is set, no status messages will be printed.

       It sets the following variables:

          PKG_CONFIG_FOUND          ... if pkg-config executable was found
          PKG_CONFIG_EXECUTABLE     ... pathname of the pkg-config program
          PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
                                        (since CMake 2.8.8)

       

       For the following variables two sets of values exist; first one is the
       common one and has the given PREFIX.  The second set contains flags
       which are given out when pkgconfig was called with the '--static'
       option.

          <XPREFIX>_FOUND          ... set to 1 if module(s) exist
          <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
          <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
          <XPREFIX>_LDFLAGS        ... all required linker flags
          <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
          <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
          <XPREFIX>_CFLAGS         ... all required cflags
          <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags

       

          <XPREFIX> = <PREFIX>        for common case
          <XPREFIX> = <PREFIX>_STATIC for static linking

       

       There are some special variables whose prefix depends on the count of
       given modules.  When there is only one module, <PREFIX> stays
       unchanged.  When there are multiple modules, the prefix will be
       changed to <PREFIX>_<MODNAME>:

          <XPREFIX>_VERSION    ... version of the module
          <XPREFIX>_PREFIX     ... prefix-directory of the module
          <XPREFIX>_INCLUDEDIR ... include-dir of the module
          <XPREFIX>_LIBDIR     ... lib-dir of the module

       

          <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
          <XPREFIX> = <PREFIX>_<MODNAME>

       

       A <MODULE> parameter can have the following formats:

          {MODNAME}            ... matches any version
          {MODNAME}>={VERSION} ... at least version <VERSION> is required
          {MODNAME}={VERSION}  ... exactly version <VERSION> is required
          {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

       

       Examples

          pkg_check_modules (GLIB2   glib-2.0)

       

          pkg_check_modules (GLIB2   glib-2.0>=2.10)
            requires at least version 2.10 of glib2 and defines e.g.
              GLIB2_VERSION=2.10.3

       

          pkg_check_modules (FOO     glib-2.0>=2.10 gtk+-2.0)
            requires both glib2 and gtk2, and defines e.g.
              FOO_glib-2.0_VERSION=2.10.3
              FOO_gtk+-2.0_VERSION=2.8.20

       

          pkg_check_modules (XRENDER REQUIRED xrender)
            defines e.g.:
              XRENDER_LIBRARIES=Xrender;X11
              XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

  FindPostgreSQL
       Find the PostgreSQL installation.

       In Windows, we make the assumption that, if the PostgreSQL files are
       installed, the default directory will be C:\Program Files\PostgreSQL.

       This module defines

         PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
         PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
         PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)


  FindProducer
        

       Though Producer isn't directly part of OpenSceneGraph, its primary
       user is OSG so I consider this part of the Findosg* suite used to find
       OpenSceneGraph components.  You'll notice that I accept OSGDIR as an
       environment path.

       Each component is separate and you must opt in to each module.  You
       must also opt into OpenGL (and OpenThreads?) as these modules won't do
       it for you.  This is to allow you control over your own system piece
       by piece in case you need to opt out of certain components or change
       the Find behavior for a particular module (perhaps because the default
       FindOpenGL.cmake module doesn't work with your system as an example).
       If you want to use a more convenient module that includes everything,
       use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
       modules.

       Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
       if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
       to find the headers

       $PRODUCER_DIR is an environment variable that would correspond to the
       ./configure --prefix=$PRODUCER_DIR used in building osg.

       Created by Eric Wing.

  FindProtobuf
        

       Locate and configure the Google Protocol Buffers library.

       The following variables can be set and are optional:

          PROTOBUF_SRC_ROOT_FOLDER - When compiling with MSVC, if this cache variable is set
                                     the protobuf-default VS project build locations
                                     (vsprojects/Debug & vsprojects/Release) will be searched
                                     for libraries and binaries.

       

          PROTOBUF_IMPORT_DIRS     - List of additional directories to be searched for
                                     imported .proto files. (New in CMake 2.8.8)

       

       Defines the following variables:

          PROTOBUF_FOUND - Found the Google Protocol Buffers library (libprotobuf & header files)
          PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers
          PROTOBUF_LIBRARIES - The protobuf libraries

       [New in CMake 2.8.5]

          PROTOBUF_PROTOC_LIBRARIES - The protoc libraries
          PROTOBUF_LITE_LIBRARIES - The protobuf-lite libraries

       

       The following cache variables are also available to set or use:

          PROTOBUF_LIBRARY - The protobuf library
          PROTOBUF_PROTOC_LIBRARY   - The protoc library
          PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers
          PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler

       [New in CMake 2.8.5]

          PROTOBUF_LIBRARY_DEBUG - The protobuf library (debug)
          PROTOBUF_PROTOC_LIBRARY_DEBUG   - The protoc library (debug)
          PROTOBUF_LITE_LIBRARY - The protobuf lite library
          PROTOBUF_LITE_LIBRARY_DEBUG - The protobuf lite library (debug)

       

         ====================================================================
         Example:

       

          find_package(Protobuf REQUIRED)

          add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
          target_link_libraries(bar ${PROTOBUF_LIBRARIES})

       

       NOTE: You may need to link against pthreads, depending

              on the platform.

       

       NOTE: The PROTOBUF_GENERATE_CPP macro & add_executable() or

  FindPythonInterp
       Find python interpreter

       This module finds if Python interpreter is installed and determines
       where the executables are.  This code sets the following variables:

         PYTHONINTERP_FOUND         - Was the Python executable found
         PYTHON_EXECUTABLE          - path to the Python interpreter

       

         PYTHON_VERSION_STRING      - Python version found e.g. 2.5.2
         PYTHON_VERSION_MAJOR       - Python major version found e.g. 2
         PYTHON_VERSION_MINOR       - Python minor version found e.g. 5
         PYTHON_VERSION_PATCH       - Python patch version found e.g. 2

       

       The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
       of version numbers that should be taken into account when searching
       for Python.  You need to set this variable before calling
       find_package(PythonInterp).

  FindPythonLibs
       Find python libraries

       This module finds if Python is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PYTHONLIBS_FOUND           - have the Python libs been found
         PYTHON_LIBRARIES           - path to the python library
         PYTHON_INCLUDE_PATH        - path to where Python.h is found (deprecated)
         PYTHON_INCLUDE_DIRS        - path to where Python.h is found
         PYTHON_DEBUG_LIBRARIES     - path to the debug library (deprecated)
         PYTHONLIBS_VERSION_STRING  - version of the Python libs found (since CMake 2.8.8)

       

       The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
       of version numbers that should be taken into account when searching
       for Python.  You need to set this variable before calling
       find_package(PythonLibs).

  FindQt
       Searches for all installed versions of QT.

       This should only be used if your project can work with multiple
       versions of QT.  If not, you should just directly use FindQt4 or
       FindQt3.  If multiple versions of QT are found on the machine, then
       The user must set the option DESIRED_QT_VERSION to the version they
       want to use.  If only one version of qt is found on the machine, then
       the DESIRED_QT_VERSION is set to that version and the matching FindQt3
       or FindQt4 module is included.  Once the user sets DESIRED_QT_VERSION,
       then the FindQt3 or FindQt4 module is included.

         QT_REQUIRED if this is set to TRUE then if CMake can 
                     not find QT4 or QT3 an error is raised 
                     and a message is sent to the user.

       

         DESIRED_QT_VERSION OPTION is created
         QT4_INSTALLED is set to TRUE if qt4 is found.
         QT3_INSTALLED is set to TRUE if qt3 is found.


  FindQt3
       Locate Qt include paths and libraries

       This module defines:

         QT_INCLUDE_DIR    - where to find qt.h, etc.
         QT_LIBRARIES      - the libraries to link against to use Qt.
         QT_DEFINITIONS    - definitions to use when
                             compiling code that uses Qt.
         QT_FOUND          - If false, don't try to use Qt.
         QT_VERSION_STRING - the version of Qt found

       

       If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
       TRUE

       Also defined, but not for general use are:

         QT_MOC_EXECUTABLE, where to find the moc tool.
         QT_UIC_EXECUTABLE, where to find the uic tool.
         QT_QT_LIBRARY, where to find the Qt library.
         QT_QTMAIN_LIBRARY, where to find the qtmain
          library. This is only required by Qt3 on Windows.


  FindQt4
       Find QT 4

       This module can be used to find Qt4.  The most important issue is that
       the Qt4 qmake is available via the system path.  This qmake is then
       used to detect basically everything else.  This module defines a
       number of key variables and macros.  The variable QT_USE_FILE is set
       which is the path to a CMake file that can be included to compile Qt 4
       applications and libraries.  It sets up the compilation environment
       for include directories, preprocessor defines and populates a
       QT_LIBRARIES variable.

       Typical usage could be something like:

          find_package(Qt4 4.4.3 REQUIRED QtCore QtGui QtXml)
          include(${QT_USE_FILE})
          add_executable(myexe main.cpp)
          target_link_libraries(myexe ${QT_LIBRARIES})

       

       The minimum required version can be specified using the standard
       find_package()-syntax (see example above).  For compatibility with
       older versions of FindQt4.cmake it is also possible to set the
       variable QT_MIN_VERSION to the minimum required version of Qt4 before
       the find_package(Qt4) command.  If both are used, the version used in
       the find_package() command overrides the one from QT_MIN_VERSION.

       When using the components argument, QT_USE_QT* variables are
       automatically set for the QT_USE_FILE to pick up.  If one wishes to
       manually set them, the available ones to set include:

                           QT_DONT_USE_QTCORE
                           QT_DONT_USE_QTGUI
                           QT_USE_QT3SUPPORT
                           QT_USE_QTASSISTANT
                           QT_USE_QAXCONTAINER
                           QT_USE_QAXSERVER
                           QT_USE_QTDESIGNER
                           QT_USE_QTMOTIF
                           QT_USE_QTMAIN
                           QT_USE_QTMULTIMEDIA
                           QT_USE_QTNETWORK
                           QT_USE_QTNSPLUGIN
                           QT_USE_QTOPENGL
                           QT_USE_QTSQL
                           QT_USE_QTXML
                           QT_USE_QTSVG
                           QT_USE_QTTEST
                           QT_USE_QTUITOOLS
                           QT_USE_QTDBUS
                           QT_USE_QTSCRIPT
                           QT_USE_QTASSISTANTCLIENT
                           QT_USE_QTHELP
                           QT_USE_QTWEBKIT
                           QT_USE_QTXMLPATTERNS
                           QT_USE_PHONON
                           QT_USE_QTSCRIPTTOOLS
                           QT_USE_QTDECLARATIVE

       

         QT_USE_IMPORTED_TARGETS 
               If this variable is set to TRUE, FindQt4.cmake will create imported
               library targets for the various Qt libraries and set the 
               library variables like QT_QTCORE_LIBRARY to point at these imported
               targets instead of the library file on disk. This provides much better 
               handling of the release and debug versions of the Qt libraries and is 
              also always backwards compatible, except for the case that dependencies
              of libraries are exported, these will then also list the names of the 
              imported targets as dependency and not the file location on disk. This
              is much more flexible, but requires that FindQt4.cmake is executed before
              such an exported dependency file is processed.

       

       There are also some files that need processing by some Qt tools such
       as moc and uic.  Listed below are macros that may be used to process
       those files.

         
         macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
               create moc code from a list of files containing Qt class with
               the Q_OBJECT declaration.  Per-direcotry preprocessor definitions 
               are also added.  Options may be given to moc, such as those found
               when executing "moc -help".  

       

         macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
               create code from a list of Qt designer ui files.
               Options may be given to uic, such as those found
               when executing "uic -help"

       

         macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
               create code from a list of Qt resource files.
               Options may be given to rcc, such as those found
               when executing "rcc -help"

       

         macro QT4_GENERATE_MOC(inputfile outputfile )
               creates a rule to run moc on infile and create outfile.
               Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
               because you need a custom filename for the moc file or something similar.

       

         macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
               This macro is still experimental.
               It can be used to have moc automatically handled.
               So if you have the files foo.h and foo.cpp, and in foo.h a 
               a class uses the Q_OBJECT macro, moc has to run on it. If you don't
               want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
               #include "foo.moc"
               in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
               scan all listed files at cmake-time for such included moc files and if it finds
               them cause a rule to be generated to run moc at build time on the 
               accompanying header file foo.h.
               If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

       

         macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
               create a the interface header and implementation files with the 
               given basename from the given interface xml file and add it to 
               the list of sources

       

         macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
               create the interface header and implementation files 
               for all listed interface xml files
               the name will be automatically determined from the name of the xml file

       

         macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
               create a dbus adaptor (header and implementation file) from the xml file
               describing the interface, and add it to the list of sources. The adaptor
               forwards the calls to a parent class, defined in parentheader and named
               parentclassname. The name of the generated files will be
               <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
               If <classname> is provided, then it will be used as the classname of the
               adaptor itself.

       

         macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
               generate the xml interface file from the given header.
               If the optional argument interfacename is omitted, the name of the 
               interface file is constructed from the basename of the header with
               the suffix .xml appended.
               Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

       

         macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ... 
                                       ts_files ... OPTIONS ...)

               in:  directories sources ts_files
               options: flags to pass to lupdate, such as -extensions to specify
               extensions for a directory scan.
               generates commands to create .ts (vie lupdate) and .qm
               (via lrelease) - files from directories and/or sources. The ts files are 
               created and/or updated in the source tree (unless given with full paths).
               The qm files are generated in the build tree.
               Updating the translations can be done by adding the qm_files
               to the source list of your library/executable, so they are
               always updated, or by adding a custom target to control when
               they get updated/generated.

       

         macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
               out: qm_files
               in:  ts_files
               generates commands to create .qm from .ts - files. The generated
               filenames can be found in qm_files. The ts_files
               must exists and are not updated in any way.

       The Qt toolkit may contain both debug and release libraries.  In that
       case, the following library variables will contain both.  You do not
       need to use these variables if you include QT_USE_FILE, and use

  FindQuickTime
        

       Locate QuickTime This module defines QUICKTIME_LIBRARY
       QUICKTIME_FOUND, if false, do not try to link to gdal
       QUICKTIME_INCLUDE_DIR, where to find the headers

       $QUICKTIME_DIR is an environment variable that would correspond to the
       ./configure --prefix=$QUICKTIME_DIR

       Created by Eric Wing.

  FindRTI
       Try to find M&S HLA RTI libraries

       This module finds if any HLA RTI is installed and locates the standard
       RTI include files and libraries.

       RTI is a simulation infrastructure standardized by IEEE and SISO.  It
       has a well defined C++ API that assures that simulation applications
       are independent on a particular RTI implementation.

         http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

       

       This code sets the following variables:

         RTI_INCLUDE_DIR = the directory where RTI includes file are found
         RTI_LIBRARIES = The libraries to link against to use RTI
         RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
         RTI_FOUND = Set to FALSE if any HLA RTI was not found

       

       Report problems to <certi-devel@nongnu.org>

  FindRuby
       Find Ruby

       This module finds if Ruby is installed and determines where the
       include files and libraries are.  Ruby 1.8 and 1.9 are supported.

       The minimum required version of Ruby can be specified using the
       standard syntax, e.g.  FIND_PACKAGE(Ruby 1.8)

       It also determines what the name of the library is.  This code sets
       the following variables:

         RUBY_EXECUTABLE   = full path to the ruby binary
         RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
         RUBY_LIBRARY      = full path to the ruby library
         RUBY_VERSION      = the version of ruby which was found, e.g. "1.8.7"
         RUBY_FOUND        = set to true if ruby ws found successfully

       

         RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it


  FindSDL
        

       Locate SDL library This module defines SDL_LIBRARY, the name of the
       library to link against SDL_FOUND, if false, do not try to link to SDL
       SDL_INCLUDE_DIR, where to find SDL.h

       This module responds to the the flag: SDL_BUILDING_LIBRARY If this is
       defined, then no SDL_main will be linked in because only applications
       need main().  Otherwise, it is assumed you are building an application
       and this module will attempt to locate and set the the proper link
       flags as part of the returned SDL_LIBRARY variable.

       Don't forget to include SDLmain.h and SDLmain.m your project for the
       OS X framework based version.  (Other versions link to -lSDLmain which
       this module will try to find on your behalf.) Also for OS X, this
       module will automatically add the -framework Cocoa on your behalf.

       

       Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
       configuration and no SDL_LIBRARY, it means CMake did not find your SDL
       library (SDL.dll, libsdl.so, SDL.framework, etc).  Set
       SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
       Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
       value as appropriate.  These values are used to generate the final
       SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
       does not get created.

       

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02

       Modified by Eric Wing.  Added code to assist with automated building
       by using environmental variables and providing a more
       controlled/consistent search behavior.  Added new modifications to
       recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
       Also corrected the header search path to follow "proper" SDL
       guidelines.  Added a search for SDLmain which is needed by some
       platforms.  Added a search for threads which is needed by some
       platforms.  Added needed compile switches for MinGW.

       On OSX, this will prefer the Framework version (if found) over others.
       People will have to manually change the cache values of SDL_LIBRARY to
       override this selection or set the CMake environment
       CMAKE_INCLUDE_PATH to modify the search paths.

       Note that the header path has changed from SDL/SDL.h to just SDL.h
       This needed to change because "proper" SDL convention is #include
       "SDL.h", not <SDL/SDL.h>.  This is done for portability reasons
       because not all systems place things in SDL/ (see FreeBSD).

  FindSDL_image
        

       Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the
       name of the library to link against SDLIMAGE_FOUND, if false, do not

       Locates the SDL_sound library

  FindSDL_ttf
        

       Locate SDL_ttf library This module defines SDLTTF_LIBRARY, the name of
       the library to link against SDLTTF_FOUND, if false, do not try to link
       to SDL SDLTTF_INCLUDE_DIR, where to find SDL/SDL.h

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module, but with modifications to recognize OS X frameworks and
       additional Unix paths (FreeBSD, etc).

  FindSWIG
       Find SWIG

       This module finds an installed SWIG.  It sets the following variables:

         SWIG_FOUND - set to true if SWIG is found
         SWIG_DIR - the directory where swig is installed
         SWIG_EXECUTABLE - the path to the swig executable
         SWIG_VERSION   - the version number of the swig executable

       

       The minimum required version of SWIG can be specified using the
       standard syntax, e.g.  FIND_PACKAGE(SWIG 1.1)

       All information is collected from the SWIG_EXECUTABLE so the version
       to be found can be changed from the command line by means of setting
       SWIG_EXECUTABLE


  FindSelfPackers
       Find upx

       This module looks for some executable packers (i.e.  softwares that
       compress executables or shared libs into on-the-fly self-extracting
       executables or shared libs.  Examples:

         UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html


  FindSquish
       -- Typical Use

       

       This module can be used to find Squish (currently support is aimed at
       version 3).

         SQUISH_FOUND                    If false, don't try to use Squish

       

         SQUISH_INSTALL_DIR              The Squish installation directory (containing bin, lib, etc)
         SQUISH_SERVER_EXECUTABLE        The squishserver executable
         SQUISH_CLIENT_EXECUTABLE        The squishrunner executable

       

         SQUISH_INSTALL_DIR_FOUND        Was the install directory found?
         SQUISH_SERVER_EXECUTABLE_FOUND  Was the server executable found?
         SQUISH_CLIENT_EXECUTABLE_FOUND  Was the client executable found?

       

       macro SQUISH_ADD_TEST(testName applicationUnderTest testSuite
       testCase)

         ENABLE_TESTING()
         FIND_PACKAGE(Squish)
         IF (SQUISH_FOUND)
           SQUISH_ADD_TEST(myTestName myApplication testSuiteName testCaseName)
         ENDIF (SQUISH_FOUND)

       


  FindSubversion
       Extract information from a subversion working copy

       The module defines the following variables:

         Subversion_SVN_EXECUTABLE - path to svn command line client
         Subversion_VERSION_SVN - version of svn command line client
         Subversion_FOUND - true if the command line client was found
         SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

       

       The minimum required version of Subversion can be specified using the
       standard syntax, e.g.  FIND_PACKAGE(Subversion 1.4)

       If the command line client executable is found two macros are defined:

         Subversion_WC_INFO(<dir> <var-prefix>)
         Subversion_WC_LOG(<dir> <var-prefix>)

       Subversion_WC_INFO extracts information of a subversion working copy
       at a given location.  This macro defines the following variables:

         <var-prefix>_WC_URL - url of the repository (at <dir>)
         <var-prefix>_WC_ROOT - root url of the repository
         <var-prefix>_WC_REVISION - current revision
         <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
         <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
         <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
         <var-prefix>_WC_INFO - output of command `svn info <dir>'

       Subversion_WC_LOG retrieves the log message of the base revision of a
       subversion working copy at a given location.  This macro defines the
       variable:

         <var-prefix>_LAST_CHANGED_LOG - last log of base revision

       Example usage:

         FIND_PACKAGE(Subversion)
         IF(SUBVERSION_FOUND)
           Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
           MESSAGE("Current revision is ${Project_WC_REVISION}")
           Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
           MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
         ENDIF(SUBVERSION_FOUND)


  FindTCL
       TK_INTERNAL_PATH was removed.

       This module finds if Tcl is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TCL_FOUND              = Tcl was found
         TK_FOUND               = Tk was found
         TCLTK_FOUND            = Tcl and Tk were found
         TCL_LIBRARY            = path to Tcl library (tcl tcl80)
         TCL_INCLUDE_PATH       = path to where tcl.h can be found
         TCL_TCLSH              = path to tclsh binary (tcl tcl80)
         TK_LIBRARY             = path to Tk library (tk tk80 etc)
         TK_INCLUDE_PATH        = path to where tk.h can be found
         TK_WISH                = full path to the wish executable

       

       In an effort to remove some clutter and clear up some issues for
       people who are not necessarily Tcl/Tk gurus/developpers, some
       variables were moved or removed.  Changes compared to CMake 2.4 are:

          => they were only useful for people writing Tcl/Tk extensions.
          => these libs are not packaged by default with Tcl/Tk distributions. 
             Even when Tcl/Tk is built from source, several flavors of debug libs
             are created and there is no real reason to pick a single one
             specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx). 
             Let's leave that choice to the user by allowing him to assign 
             TCL_LIBRARY to any Tcl library, debug or not.
          => this ended up being only a Win32 variable, and there is a lot of
             confusion regarding the location of this file in an installed Tcl/Tk
             tree anyway (see 8.5 for example). If you need the internal path at
             this point it is safer you ask directly where the *source* tree is
             and dig from there.


  FindTIFF
       Find TIFF library

       Find the native TIFF includes and library This module defines

         TIFF_INCLUDE_DIR, where to find tiff.h, etc.
         TIFF_LIBRARIES, libraries to link against to use TIFF.
         TIFF_FOUND, If false, do not try to use TIFF.

       also defined, but not for general use are

         TIFF_LIBRARY, where to find the TIFF library.


  FindTclStub
       TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

       This module finds Tcl stub libraries.  It first finds Tcl include
       files and libraries by calling FindTCL.cmake.  How to Use the Tcl
       Stubs Library:

          http://tcl.activestate.com/doc/howto/stubs.html

       Using Stub Libraries:

          http://safari.oreilly.com/0130385603/ch48lev1sec3

       This code sets the following variables:

         TCL_STUB_LIBRARY       = path to Tcl stub library
         TK_STUB_LIBRARY        = path to Tk stub library
         TTK_STUB_LIBRARY       = path to ttk stub library

       

       In an effort to remove some clutter and clear up some issues for
       people who are not necessarily Tcl/Tk gurus/developpers, some
       variables were moved or removed.  Changes compared to CMake 2.4 are:

          => these libs are not packaged by default with Tcl/Tk distributions. 
             Even when Tcl/Tk is built from source, several flavors of debug libs
             are created and there is no real reason to pick a single one
             specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx). 
             Let's leave that choice to the user by allowing him to assign 
             TCL_STUB_LIBRARY to any Tcl library, debug or not.


  FindTclsh
       Find tclsh

       This module finds if TCL is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TCLSH_FOUND = TRUE if tclsh has been found
         TCL_TCLSH = the path to the tclsh executable

       In cygwin, look for the cygwin version first.  Don't look for it later
       to avoid finding the cygwin version on a Win32 build.

  FindThreads
       This module determines the thread library of the system.

       The following variables are set

         CMAKE_THREAD_LIBS_INIT     - the thread library
         CMAKE_USE_SPROC_INIT       - are we using sproc?
         CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
         CMAKE_USE_PTHREADS_INIT    - are we using pthreads
         CMAKE_HP_PTHREADS_INIT     - are we using hp pthreads

       For systems with multiple thread libraries, caller can set

         CMAKE_THREAD_PREFER_PTHREAD


  FindUnixCommands
       Find unix commands from cygwin

       This module looks for some usual Unix commands.


  FindVTK
       Find a VTK installation or build tree.

       VTK_FOUND is set to false.

         VTK_FOUND         - Set to true when VTK is found.
         VTK_USE_FILE      - CMake file to use VTK.
         VTK_MAJOR_VERSION - The VTK major version number.
         VTK_MINOR_VERSION - The VTK minor version number 
                              (odd non-release).
         VTK_BUILD_VERSION - The VTK patch level 
                              (meaningless for odd minor).
         VTK_INCLUDE_DIRS  - Include directories for VTK
         VTK_LIBRARY_DIRS  - Link directories for VTK libraries
         VTK_KITS          - List of VTK kits, in CAPS 
                             (COMMON,IO,) etc.

                             (TCL, PYHTON,) etc.

       The following cache entries must be set by the user to locate VTK:

         VTK_DIR  - The directory containing VTKConfig.cmake.  
                    This is either the root of the build tree,
                    or the lib/vtk directory.  This is the 
                    only cache entry.

       The following variables are set for backward compatibility and should
       not be used in new code:

         USE_VTK_FILE - The full path to the UseVTK.cmake file.
                        This is provided for backward 
                        compatibility.  Use VTK_USE_FILE 
                        instead.

       


  FindWget
       Find wget

       This module looks for wget.  This module defines the following values:

         WGET_EXECUTABLE: the full path to the wget tool.
         WGET_FOUND: True if wget has been found.


  FindWish
       Find wish installation

       This module finds if TCL is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TK_WISH = the path to the wish executable

       

       if UNIX is defined, then it will look for the cygwin version first

  FindX11
       Find X11 installation

       Try to find X11 on UNIX systems.  The following values are defined

         X11_FOUND        - True if X11 is available
         X11_INCLUDE_DIR  - include directories to use X11
         X11_LIBRARIES    - link against these to use X11

       

       and also the following more fine grained variables: Include paths:
       X11_ICE_INCLUDE_PATH, X11_ICE_LIB, X11_ICE_FOUND

                       X11_SM_INCLUDE_PATH,           X11_SM_LIB,         X11_SM_FOUND

         ZLIB_VERSION_PATCH  - The patch version of zlib
         ZLIB_VERSION_TWEAK  - The tweak version of zlib

       

       The following variable are provided for backward compatibility

         ZLIB_MAJOR_VERSION  - The major version of zlib
         ZLIB_MINOR_VERSION  - The minor version of zlib
         ZLIB_PATCH_VERSION  - The patch version of zlib

       

       An includer may set ZLIB_ROOT to a zlib installation root to tell this
       module where to look.

  Findosg
        

       

       NOTE: It is highly recommended that you use the new
       FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
       Find module directly.

       This is part of the Findosg* suite used to find OpenSceneGraph
       components.  Each component is separate and you must opt in to each
       module.  You must also opt into OpenGL and OpenThreads (and Producer
       if needed) as these modules won't do it for you.  This is to allow you
       control over your own system piece by piece in case you need to opt
       out of certain components or change the Find behavior for a particular
       module (perhaps because the default FindOpenGL.cmake module doesn't
       work with your system as an example).  If you want to use a more
       convenient module that includes everything, use the
       FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

       Locate osg This module defines

       OSG_FOUND - Was the Osg found? OSG_INCLUDE_DIR - Where to find the
       headers OSG_LIBRARIES - The libraries to link against for the OSG (use
       this)

       OSG_LIBRARY - The OSG library OSG_LIBRARY_DEBUG - The OSG debug
       library

       $OSGDIR is an environment variable that would correspond to the

  FindosgAnimation
        

       This is part of the Findosg* suite used to find OpenSceneGraph
       components.  Each component is separate and you must opt in to each
       module.  You must also opt into OpenGL and OpenThreads (and Producer
       if needed) as these modules won't do it for you.  This is to allow you
       control over your own system piece by piece in case you need to opt
       out of certain components or change the Find behavior for a particular
       module (perhaps because the default FindOpenGL.cmake module doesn't
       work with your system as an example).  If you want to use a more
       convenient module that includes everything, use the
       FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

       This CMake file contains two macros to assist with searching for OSG
       libraries and nodekits.


  FindwxWidgets
       Find a wxWidgets (a.k.a., wxWindows) installation.

       This module finds if wxWidgets is installed and selects a default
       configuration to use.  wxWidgets is a modular library.  To specify the
       modules that you will use, you need to name them as components to the
       package:

       FIND_PACKAGE(wxWidgets COMPONENTS core base ...)

       There are two search branches: a windows style and a unix style.  For
       windows, the following variables are searched for and set to defaults
       in case of multiple choices.  Change them if the defaults are not
       desired (i.e., these are the only variables you should change to
       select a configuration):

         wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                   (e.g., C:/wxWidgets-2.6.3).
         wxWidgets_LIB_DIR       - Path to wxWidgets libraries
                                   (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
         wxWidgets_CONFIGURATION - Configuration to use
                                   (e.g., msw, mswd, mswu, mswunivud, etc.)
         wxWidgets_EXCLUDE_COMMON_LIBRARIES
                                 - Set to TRUE to exclude linking of
                                   commonly required libs (e.g., png tiff
                                   jpeg zlib regex expat).

       

       For unix style it uses the wx-config utility.  You can select between
       debug/release, unicode/ansi, universal/non-universal, and
       static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
       the following variables:

         wxWidgets_USE_DEBUG
         wxWidgets_USE_UNICODE
         wxWidgets_USE_UNIVERSAL
         wxWidgets_USE_STATIC

       

       There is also a wxWidgets_CONFIG_OPTIONS variable for all other
       options that need to be passed to the wx-config utility.  For example,
       to use the base toolkit found in the /usr/local path, set the variable
       (before calling the FIND_PACKAGE command) as such:

         SET(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)

       

       The following are set after the configuration is done for both windows
       and unix style:

         wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
         wxWidgets_INCLUDE_DIRS     - Include directories for WIN32
                                      i.e., where to find "wx/wx.h" and
                                      "wx/setup.h"; possibly empty for unices.
         wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
         wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                                      rpath on UNIX. Typically an empty string
                                      in WIN32 environment.
         wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                      against WX, e.g. WXUSINGDLL
         wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
                                      against WX debug builds, e.g. __WXDEBUG__
         wxWidgets_CXX_FLAGS        - Include dirs and compiler flags for
                                      unices, empty on WIN32. Essentially
                                      "`wx-config --cxxflags`".
         wxWidgets_USE_FILE         - Convenience include file.

       

       Sample usage:

          # Note that for MinGW users the order of libs is important!
          FIND_PACKAGE(wxWidgets COMPONENTS net gl core base)
          IF(wxWidgets_FOUND)
            INCLUDE(${wxWidgets_USE_FILE})
            # and for each of your dependent executable/library targets:
            TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
          ENDIF(wxWidgets_FOUND)

       

       If wxWidgets is required (i.e., not an optional part):

          FIND_PACKAGE(wxWidgets REQUIRED net gl core base)
          INCLUDE(${wxWidgets_USE_FILE})
          # and for each of your dependent executable/library targets:
          TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})


  FindwxWindows
       Find wxWindows (wxWidgets) installation

       This module finds if wxWindows/wxWidgets is installed and determines
       where the include files and libraries are.  It also determines what
       the name of the library is.  Please note this file is DEPRECATED and
       replaced by FindwxWidgets.cmake.  This code sets the following
       variables:

         WXWINDOWS_FOUND     = system has WxWindows
         WXWINDOWS_LIBRARIES = path to the wxWindows libraries
                               on Unix/Linux with additional
                               linker flags from
                               "wx-config --libs"
         CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
                                      essentially "`wx-config --cxxflags`"
                                      on Linux
         WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
         WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
                                       Unix
         WXWINDOWS_DEFINITIONS      = extra defines

  FortranCInterface
       Fortran/C Interface Detection

       This module automatically detects the API by which C and Fortran
       languages interact.  Variables indicate if the mangling is found:

          FortranCInterface_GLOBAL_FOUND = Global subroutines and functions
          FortranCInterface_MODULE_FOUND = Module subroutines and functions
                                           (declared by "MODULE PROCEDURE")

       A function is provided to generate a C header file containing macros
       to mangle symbol names:

          FortranCInterface_HEADER(<file>
                                   [MACRO_NAMESPACE <macro-ns>]
                                   [SYMBOL_NAMESPACE <ns>]
                                   [SYMBOLS [<module>:]<function> ...])

       It generates in <file> definitions of the following macros:

          #define FortranCInterface_GLOBAL (name,NAME) ...
          #define FortranCInterface_GLOBAL_(name,NAME) ...
          #define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
          #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...

       These macros mangle four categories of Fortran symbols, respectively:

          - Global symbols without '_': call mysub()
          - Global symbols with '_'   : call my_sub()
          - Module symbols without '_': use mymod; call mysub()
          - Module symbols with '_'   : use mymod; call my_sub()

       If mangling for a category is not known, its macro is left undefined.
       All macros require raw names in both lower case and upper case.  The
       MACRO_NAMESPACE option replaces the default "FortranCInterface_"
       prefix with a given namespace "<macro-ns>".

       The SYMBOLS option lists symbols to mangle automatically with C
       preprocessor definitions:

          <function>          ==> #define <ns><function> ...
          <module>:<function> ==> #define <ns><module>_<function> ...

       If the mangling for some symbol is not known then no preprocessor
       definition is created, and a warning is displayed.  The
       SYMBOL_NAMESPACE option prefixes all preprocessor definitions
       generated by the SYMBOLS option with a given namespace "<ns>".

       Example usage:

          include(FortranCInterface)
          FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")

       This creates a "FC.h" header that defines mangling macros FC_GLOBAL(),
       FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().

       Example usage:

          include(FortranCInterface)
          FortranCInterface_HEADER(FCMangle.h
                                   MACRO_NAMESPACE "FC_"
                                   SYMBOL_NAMESPACE "FC_"
                                   SYMBOLS mysub mymod:my_sub)

       This creates a "FCMangle.h" header that defines the same FC_*()
       mangling macros as the previous example plus preprocessor symbols
       FC_mysub and FC_mymod_my_sub.

       Another function is provided to verify that the Fortran and C/C++
       compilers work together:

          FortranCInterface_VERIFY([CXX] [QUIET])

       It tests whether a simple test executable using Fortran and C (and C++
       when the CXX option is given) compiles and links successfully.  The
       result is stored in the cache entry FortranCInterface_VERIFIED_C (or
       FortranCInterface_VERIFIED_CXX if CXX is given) as a boolean.  If the
       check fails and QUIET is not given the function terminates with a
       FATAL_ERROR message describing the problem.  The purpose of this check
       is to stop a build early for incompatible compiler combinations.

       FortranCInterface is aware of possible GLOBAL and MODULE manglings for
       many Fortran compilers, but it also provides an interface to specify
       new possible manglings.  Set the variables

          FortranCInterface_GLOBAL_SYMBOLS
          FortranCInterface_MODULE_SYMBOLS

       before including FortranCInterface to specify manglings of the symbols
       "MySub", "My_Sub", "MyModule:MySub", and "My_Module:My_Sub".  For
       example, the code:

          set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
            #                                  ^^^^^  ^^^^^^   ^^^^^
          set(FortranCInterface_MODULE_SYMBOLS
              __mymodule_MOD_mysub __my_module_MOD_my_sub)
            #   ^^^^^^^^     ^^^^^   ^^^^^^^^^     ^^^^^^
          include(FortranCInterface)

       tells FortranCInterface to try given GLOBAL and MODULE manglings.
       (The carets point at raw symbol names for clarity in this example but
       are not needed.)

  GNUInstallDirs
       Define GNU standard installation directories

       Provides install directory variables as defined for GNU software:

         http://www.gnu.org/prep/standards/html_node/Directory-Variables.html

       Inclusion of this module defines the following variables:

         CMAKE_INSTALL_<dir>      - destination for files of a given type
         CMAKE_INSTALL_FULL_<dir> - corresponding absolute path

       where <dir> is one of:

         BINDIR           - user executables (bin)
         SBINDIR          - system admin executables (sbin)
         LIBEXECDIR       - program executables (libexec)
         SYSCONFDIR       - read-only single-machine data (etc)
         SHAREDSTATEDIR   - modifiable architecture-independent data (com)
         LOCALSTATEDIR    - modifiable single-machine data (var)
         LIBDIR           - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)
         INCLUDEDIR       - C header files (include)
         OLDINCLUDEDIR    - C header files for non-gcc (/usr/include)
         DATAROOTDIR      - read-only architecture-independent data root (share)
         DATADIR          - read-only architecture-independent data (DATAROOTDIR)
         INFODIR          - info documentation (DATAROOTDIR/info)
         LOCALEDIR        - locale-dependent data (DATAROOTDIR/locale)
         MANDIR           - man documentation (DATAROOTDIR/man)
         DOCDIR           - documentation root (DATAROOTDIR/doc/PROJECT_NAME)

       Each CMAKE_INSTALL_<dir> value may be passed to the DESTINATION
       options of install() commands for the corresponding file type.  If the
       includer does not define a value the above-shown default will be used
       and the value will appear in the cache for editing by the user.  Each
       CMAKE_INSTALL_FULL_<dir> value contains an absolute path constructed
       from the corresponding destination by prepending (if necessary) the
       value of CMAKE_INSTALL_PREFIX.

  GenerateExportHeader
       Function for generation of export macros for libraries

       This module provides the function GENERATE_EXPORT_HEADER() and the
       accompanying ADD_COMPILER_EXPORT_FLAGS() function.

       The GENERATE_EXPORT_HEADER function can be used to generate a file
       suitable for preprocessor inclusion which contains EXPORT macros to be
       used in library classes.

       GENERATE_EXPORT_HEADER( LIBRARY_TARGET

                    [BASE_NAME <base_name>]
                    [EXPORT_MACRO_NAME <export_macro_name>]
                    [EXPORT_FILE_NAME <export_file_name>]
                    [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
                    [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
                    [STATIC_DEFINE <static_define>]
                    [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
                    [DEFINE_NO_DEPRECATED]
                    [PREFIX_NAME <prefix_name>]

       )

       ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )

       By default GENERATE_EXPORT_HEADER() generates macro names in a file
       name determined by the name of the library.  The
       ADD_COMPILER_EXPORT_FLAGS function adds -fvisibility=hidden to
       CMAKE_CXX_FLAGS if supported, and is a no-op on Windows which does not
       need extra compiler flags for exporting support.  You may optionally
       pass a single argument to ADD_COMPILER_EXPORT_FLAGS that will be
       populated with the required CXX_FLAGS required to enable visibility
       support for the compiler/architecture in use.

       This means that in the simplest case, users of these functions will be
       equivalent to:

          add_compiler_export_flags()
          add_library(somelib someclass.cpp)
          generate_export_header(somelib)
          install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
          install(FILES
           someclass.h
           ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
          )

       

       And in the ABI header files:

          #include "somelib_export.h"
          class SOMELIB_EXPORT SomeClass {
            ...
          };

       

       The CMake fragment will generate a file in the
       ${CMAKE_CURRENT_BUILD_DIR} called somelib_export.h containing the
       macros SOMELIB_EXPORT, SOMELIB_NO_EXPORT, SOMELIB_DEPRECATED,
       SOMELIB_DEPRECATED_EXPORT and SOMELIB_DEPRECATED_NO_EXPORT.  The
       resulting file should be installed with other headers in the library.

       The BASE_NAME argument can be used to override the file name and the
       names used for the macros

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            BASE_NAME other_name
          )

       

       Generates a file called other_name_export.h containing the macros
       OTHER_NAME_EXPORT, OTHER_NAME_NO_EXPORT and OTHER_NAME_DEPRECATED etc.

       The BASE_NAME may be overridden by specifiying other options in the
       function.  For example:

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            EXPORT_MACRO_NAME OTHER_NAME_EXPORT
          )

       

       creates the macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT, but
       other macros and the generated file name is as default.

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            DEPRECATED_MACRO_NAME KDE_DEPRECATED
          )

       

       creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED.

       If LIBRARY_TARGET is a static library, macros are defined without
       values.

       If the same sources are used to create both a shared and a static
       library, the uppercased symbol ${BASE_NAME}_STATIC_DEFINE should be
       used when building the static library

          add_library(shared_variant SHARED ${lib_SRCS})
          add_library(static_variant ${lib_SRCS})
          generate_export_header(shared_variant BASE_NAME libshared_and_static)
          set_target_properties(static_variant PROPERTIES
            COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)

       

       This will cause the export macros to expand to nothing when building
       the static library.

       If DEFINE_NO_DEPRECATED is specified, then a macro
       ${BASE_NAME}_NO_DEPRECATED will be defined This macro can be used to
       remove deprecated code from preprocessor output.

          option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
          if (EXCLUDE_DEPRECATED)
            set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
          endif()
          generate_export_header(somelib ${NO_BUILD_DEPRECATED})

       

       And then in somelib:

          class SOMELIB_EXPORT SomeClass
          {
          public:
          #ifndef SOMELIB_NO_DEPRECATED
            SOMELIB_DEPRECATED void oldMethod();
          #endif
          };

       

          #ifndef SOMELIB_NO_DEPRECATED
          void SomeClass::oldMethod() {  }
          #endif

       

       If PREFIX_NAME is specified, the argument will be used as a prefix to
       all generated macros.

       For example:

          generate_export_header(somelib PREFIX_NAME VTK_)

       

       Generates the macros VTK_SOMELIB_EXPORT etc.

  GetPrerequisites
       Functions to analyze and list executable file prerequisites.

       This module provides functions to list the .dll, .dylib or .so files
       that an executable or shared library file depends on.  (Its
       prerequisites.)

       It uses various tools to obtain the list of required shared library
       files:

          dumpbin (Windows)
          ldd (Linux/Unix)
          otool (Mac OSX)

       The following functions are provided by this module:

          get_prerequisites
          list_prerequisites
          list_prerequisites_by_glob
          gp_append_unique
          is_file_executable
          gp_item_default_embedded_path
            (projects can override with gp_item_default_embedded_path_override)
          gp_resolve_item
            (projects can override with gp_resolve_item_override)
          gp_resolved_file_type
            (projects can override with gp_resolved_file_type_override)
          gp_file_type

       Requires CMake 2.6 or greater because it uses function, break, return
       and PARENT_SCOPE.

         GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
                           <exepath> <dirs>)

       Get the list of shared library files required by <target>.  The list
       in the variable named <prerequisites_var> should be empty on first
       entry to this function.  On exit, <prerequisites_var> will contain the
       list of required shared library files.

       <target> is the full path to an executable file.  <prerequisites_var>
       is the name of a CMake variable to contain the results.
       <exclude_system> must be 0 or 1 indicating whether to include or
       exclude "system" prerequisites.  If <recurse> is set to 1 all
       prerequisites will be found recursively, if set to 0 only direct
       prerequisites are listed.  <exepath> is the path to the top level
       executable used for @executable_path replacment on the Mac.  <dirs> is
       a list of paths where libraries might be found: these paths are
       searched first when a target without any path info is given.  Then
       standard system locations are also searched: PATH, Framework
       locations, /usr/lib...

         LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])

       Print a message listing the prerequisites of <target>.

       <target> is the name of a shared library or executable target or the
       full path to a shared library or executable file.  If <recurse> is set
       to 1 all prerequisites will be found recursively, if set to 0 only
       direct prerequisites are listed.  <exclude_system> must be 0 or 1
       indicating whether to include or exclude "system" prerequisites.  With
       <verbose> set to 0 only the full path names of the prerequisites are
       printed, set to 1 extra informatin will be displayed.

         LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)

       Print the prerequisites of shared library and executable files
       matching a globbing pattern.  <glob_arg> is GLOB or GLOB_RECURSE and
       <glob_exp> is a globbing expression used with "file(GLOB" or
       "file(GLOB_RECURSE" to retrieve a list of matching files.  If a
       matching file is executable, its prerequisites are listed.

       Any additional (optional) arguments provided are passed along as the
       optional arguments to the list_prerequisites calls.

         GP_APPEND_UNIQUE(<list_var> <value>)

       Append <value> to the list variable <list_var> only if the value is
       not already in the list.

         IS_FILE_EXECUTABLE(<file> <result_var>)

       Return 1 in <result_var> if <file> is a binary executable, 0
       otherwise.

         GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)

       Return the path that others should refer to the item by when the item
       is embedded inside a bundle.

       Override on a per-project basis by providing a project-specific
       gp_item_default_embedded_path_override function.

         GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)

       Resolve an item into an existing full path file.

       Override on a per-project basis by providing a project-specific
       gp_resolve_item_override function.

         GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)

       Return the type of <file> with respect to <original_file>.  String
       describing type of prerequisite is returned in variable named
       <type_var>.

       Use <exepath> and <dirs> if necessary to resolve non-absolute <file>
       values -- but only for non-embedded items.

       Possible types are:

          system
          local
          embedded
          other

       Override on a per-project basis by providing a project-specific
       gp_resolved_file_type_override function.

         GP_FILE_TYPE(<original_file> <file> <type_var>)

       Return the type of <file> with respect to <original_file>.  String
       describing type of prerequisite is returned in variable named
       <type_var>.

  InstallRequiredSystemLibraries
        

       By including this file, all library files listed in the variable
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS will be installed with
       INSTALL(PROGRAMS ...) into bin for WIN32 and lib for non-WIN32.  If
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP is set to TRUE before including
       this file, then the INSTALL command is not called.  The user can use
       the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install
       command and install them however they want.  If it is the MSVC
       compiler, then the microsoft run time libraries will be found and
       automatically added to the CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS, and
       installed.  If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC
       compiler, then the debug libraries are installed when available.  If
       CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY is set then only the debug
       libraries are installed when both debug and release are available.  If
       CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are
       installed as well as the CRT run time libraries.  If
       CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION is set then the libraries are
       installed to that directory rather than the default.  If
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS is NOT set, then this
       file warns about required files that do not exist.  You can set this
       variable to ON before including this file to avoid the warning.  For
       example, the Visual Studio Express editions do not include the
       redistributable files, so if you include this file on a machine with
       only VS Express installed, you'll get the warning.

  MacroAddFileDependencies
       MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)

       Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged.  There
       are usually better ways to specify the correct dependencies.

       MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a
       convenience wrapper around the OBJECT_DEPENDS source file property.
       You can just use SET_PROPERTY(SOURCE <file> APPEND PROPERTY
       OBJECT_DEPENDS depend_files) instead.

  ProcessorCount
       ProcessorCount(var)

       Determine the number of processors/cores and save value in ${var}

       Sets the variable named ${var} to the number of physical cores
       available on the machine if the information can be determined.
       Otherwise it is set to 0.  Currently this functionality is implemented
       for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS X, QNX, Sun and
       Windows.

       This function is guaranteed to return a positive integer (>=1) if it
       succeeds.  It returns 0 if there's a problem determining the processor
       count.

       Example use, in a ctest -S dashboard script:

          include(ProcessorCount)
          ProcessorCount(N)
          if(NOT N EQUAL 0)
            set(CTEST_BUILD_FLAGS -j${N})
            set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N})
          endif()

       

       This function is intended to offer an approximation of the value of
       the number of compute cores available on the current machine, such
       that you may use that value for parallel building and parallel
       testing.  It is meant to help utilize as much of the machine as seems
       reasonable.  Of course, knowledge of what else might be running on the
       machine simultaneously should be used when deciding whether to request
       a machine's full capacity all for yourself.

  SelectLibraryConfigurations
        

       select_library_configurations( basename )

       This macro takes a library base name as an argument, and will choose
       good values for basename_LIBRARY, basename_LIBRARIES,
       basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what
       has been found and set.  If only basename_LIBRARY_RELEASE is defined,
       basename_LIBRARY, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE
       will be set to the release value.  If only basename_LIBRARY_DEBUG is
       defined, then basename_LIBRARY, basename_LIBRARY_DEBUG and
       basename_LIBRARY_RELEASE will take the debug value.

       If the generator supports configuration types, then basename_LIBRARY
       and basename_LIBRARIES will be set with debug and optimized flags
       specifying the library to be used for the given configuration.  If no
       build type has been set or the generator in use does not support
       configuration types, then basename_LIBRARY and basename_LIBRARIES will
       take only the release values.

  SquishTestScript
        

       

       This script launches a GUI test using Squish.  You should not call the
       script directly; instead, you should access it via the SQUISH_ADD_TEST
       macro that is defined in FindSquish.cmake.

       This script starts the Squish server, launches the test on the client,
       and finally stops the squish server.  If any of these steps fail
       (including if the tests do not pass) then a fatal error is raised.

  UseEcos
       This module defines variables and macros required to build eCos
       application.

       This file contains the following macros:
       ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs
       ECOS_ADD_EXECUTABLE(name source1 ...  sourceN ) - create an eCos
       executable ECOS_ADJUST_DIRECTORY(VAR source1 ...  sourceN ) - adjusts
       the path of the source files and puts the result into VAR

       Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable
       the ARM ELF toolchain for the directory where it is called
       ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the
       directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the
       PowerPC toolchain for the directory where it is called

       It contains the following variables: ECOS_DEFINITIONS
       ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your
       eCos configuration file has a different name, adjust this variable for
       internal use only:

         ECOS_ADD_TARGET_LIB


  UseJava
       Use Module for Java

       This file provides functions for Java.  It is assumed that
       FindJava.cmake has already been loaded.  See FindJava.cmake for
       information on how to load Java into your CMake project.

       add_jar(TARGET_NAME SRC1 SRC2 ..  SRCN RCS1 RCS2 ..  RCSN)

       This command creates a <TARGET_NAME>.jar.  It compiles the given
       source files (SRC) and adds the given resource files (RCS) to the jar
       file.  If only resource files are given then just a jar file is
       created.

       Additional instructions:

          To add compile flags to the target you can set these flags with
          the following variable:

       

              set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)

       

          To add a path or a jar file to the class path you can do this
          with the CMAKE_JAVA_INCLUDE_PATH variable.

       

              set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)

       

          To use a different output name for the target you can set it with:

       

              set(CMAKE_JAVA_TARGET_OUTPUT_NAME shibboleet.jar)
              add_jar(foobar foobar.java)

       

          To use a different output directory than CMAKE_CURRENT_BINARY_DIR
          you can set it with:

       

              set(CMAKE_JAVA_TARGET_OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)

       

          To define an entry point in your jar you can set it with:

       

              set(CMAKE_JAVA_JAR_ENTRY_POINT com/examples/MyProject/Main)

       

          To add a VERSION to the target output name you can set it using
          CMAKE_JAVA_TARGET_VERSION. This will create a jar file with the name
          shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
          pointing to the jar with the version information.

       

              set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
              add_jar(shibboleet shibbotleet.java)

       

           If the target is a JNI library, utilize the following commands to
           create a JNI symbolic link:

       

              set(CMAKE_JNI_TARGET TRUE)
              set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
              add_jar(shibboleet shibbotleet.java)
              install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
              install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})

       

           If a single target needs to produce more than one jar from its
           java source code, to prevent the accumulation of duplicate class
           files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
           to calling the add_jar() function:

       

              set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
              add_jar(foo foo.java)

       

              set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
              add_jar(bar bar.java)

       

       Target Properties:

          The add_jar() functions sets some target properties. You can get these
          properties with the
             get_property(TARGET <target_name> PROPERTY <propery_name>)
          command.

       

          INSTALL_FILES      The files which should be installed. This is used by
                             install_jar().
          JNI_SYMLINK        The JNI symlink which should be installed.
                             This is used by install_jni_symlink().
          JAR_FILE           The location of the jar file so that you can include
                             it.
          CLASS_DIR          The directory where the class files can be found. For
                             example to use them with javah.

       

       find_jar(<VAR>

                 name | NAMES name1 [name2 ...]
                 [PATHS path1 [path2 ... ENV var]]
                 [VERSIONS version1 [version2]]
                 [DOC "cache documentation string"]
                )

       

       This command is used to find a full path to the named jar.  A cache
       entry named by <VAR> is created to stor the result of this command.
       If the full path to a jar is found the result is stored in the
       variable and the search will not repeated unless the variable is
       cleared.  If nothing is found, the result will be <VAR>-NOTFOUND, and
       the search will be attempted again next time find_jar is invoked with
       the same variable.  The name of the full path to a file that is
       searched for is specified by the names listed after NAMES argument.
       Additional search locations can be specified after the PATHS argument.
       If you require special a version of a jar file you can specify it with
       the VERSIONS argument.  The argument after DOC will be used for the
       documentation string in the cache.

       install_jar(TARGET_NAME DESTINATION)

       This command installs the TARGET_NAME files to the given DESTINATION.
       It should be called in the same scope as add_jar() or it will fail.

       install_jni_symlink(TARGET_NAME DESTINATION)

       This command installs the TARGET_NAME JNI symlinks to the given
       DESTINATION.  It should be called in the same scope as add_jar() or it
       will fail.

       create_javadoc(<VAR>

                       PACKAGES pkg1 [pkg2 ...]
                       [SOURCEPATH <sourcepath>]
                       [CLASSPATH <classpath>]
                       [INSTALLPATH <install path>]

                       [WINDOWTITLE "the title of the document"]
                       [AUTHOR TRUE|FALSE]
                       [USE TRUE|FALSE]
                       [VERSION TRUE|FALSE]
                      )

       

       Create java documentation based on files or packages.  For more
       details please read the javadoc manpage.

       There are two main signatures for create_javadoc.  The first signature
       works with package names on a path with source files:

          Example:
          create_javadoc(my_example_doc
            PACKAGES com.exmaple.foo com.example.bar
            SOURCEPATH ${CMAKE_CURRENT_SOURCE_PATH}
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )

       

       The second signature for create_javadoc works on a given list of
       files.

          create_javadoc(<VAR>
                         FILES file1 [file2 ...]
                         [CLASSPATH <classpath>]
                         [INSTALLPATH <install path>]
                         [DOCTITLE "the documentation title"]
                         [WINDOWTITLE "the title of the document"]
                         [AUTHOR TRUE|FALSE]
                         [USE TRUE|FALSE]
                         [VERSION TRUE|FALSE]
                        )

       

       Example:

          create_javadoc(my_example_doc
            FILES ${example_SRCS}
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )

       

       Both signatures share most of the options.  These options are the same
       as what you can find in the javadoc manpage.  Please look at the
       manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and VERSION.

       The documentation will be by default installed to

          ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>

       

       if you don't set the INSTALLPATH.


  UseJavaClassFilelist
        

       

       This script create a list of compiled Java class files to be added to
       a jar file.  This avoids including cmake files which get created in
       the binary directory.

       Helper script for UseJava.cmake


  UsePkgConfig
       Obsolete pkg-config module for CMake, use FindPkgConfig instead.

       

       This module defines the following macro:

       PKGCONFIG(package includedir libdir linkflags cflags)

       Calling PKGCONFIG will fill the desired information into the 4 given
       arguments, e.g.  PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
       LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT
       found or the specified software package doesn't exist, the variable
       will be empty when the function returns, otherwise they will contain
       the respective information


  UseQt4
       Use Module for QT4

       Sets up C and C++ to use Qt 4.  It is assumed that FindQt.cmake has
       already been loaded.  See FindQt.cmake for information on how to load
       Qt 4 into your CMake project.

  UseSWIG
       SWIG module for CMake

       Defines the following macros:

          SWIG_ADD_MODULE(name language [ files ])
            - Define swig module with given name and specified language
          SWIG_LINK_LIBRARIES(name [ libraries ])
            - Link libraries to swig module

       All other macros are for internal use only.  To get the actual name of
       the swig module, use: ${SWIG_MODULE_${name}_REAL_NAME}.  Set Source
       files properties such as CPLUSPLUS and SWIG_FLAGS to specify special
       behavior of SWIG.  Also global CMAKE_SWIG_FLAGS can be used to add
       special flags to all swig calls.  Another special variable is
       CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the
       swig generated module (swig -outdir option) The name-specific variable
       SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra
