+: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 3.0.0 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 3.0.0. CMake version
+|release| warns when the policy is not set and uses OLD behavior. Use
+the cmake_policy command to set it to OLD or NEW explicitly.
