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
3.19.8 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.
