# CMP0006

Installing `MACOSX_BUNDLE` targets requires a `BUNDLE DESTINATION`.

This policy determines whether the `install(TARGETS)` command must be given a `BUNDLE DESTINATION` when asked to install a target with the `MACOSX_BUNDLE` property set. CMake 2.4 and below did not distinguish application bundles from normal executables when installing targets. CMake 2.6 provides a `BUNDLE` option to the `install(TARGETS)` command that specifies rules specific to application bundles on the Mac. Projects should use this option when installing a target with the `MACOSX_BUNDLE` property set.

The `OLD` behavior for this policy is to fall back to the `RUNTIME DESTINATION` if a `BUNDLE DESTINATION` is not given. The `NEW` behavior for this policy is to produce an error if a bundle target is installed without a `BUNDLE DESTINATION`.

This policy was introduced in CMake version 2.6.0. CMake version 3.23.3 warns when the policy is not set and uses `OLD` behavior. Use the `cmake_policy()` command to set it to `OLD` or `NEW` explicitly.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
