: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 cmake_policy command to set it to OLD or NEW explicitly.
