The ``NEW`` behavior of this policy is to ignore +the ``RPATH`` settings for ``install_name`` on macOS. + +This policy was introduced in CMake version 3.9. 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 |
