CMP0042 ------- :prop_tgt:`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 :prop_tgt:`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 :prop_tgt:`INSTALL_NAME_DIR` and :variable:`CMAKE_INSTALL_NAME_DIR` variables. This policy was introduced in CMake version 3.0. CMake version |release| warns when the policy is not set and uses ``OLD`` behavior. Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. .. include:: DEPRECATED.txt
