MACOSX_RPATH is enabled by default.

CMake 2.8.12 and newer has support for using @rpath in a target’s install name. This was enabled by setting the target property MACOSX_RPATH. The @rpath in an install name is a more flexible and powerful mechanism than @executable_path or @loader_path for locating shared libraries.

CMake 3.0 and later prefer this property to be ON by default. Projects wanting @rpath in a target’s install name may remove any setting of the INSTALL_NAME_DIR and CMAKE_INSTALL_NAME_DIR variables.

This policy was introduced in CMake version 3.0. CMake version 3.7.1 warns when the policy is not set and uses OLD behavior. Use the cmake_policy command to set it to OLD or NEW explicitly.


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