Explicit invocations of ``cmake_policy(PUSH)`` and +``cmake_policy(POP)`` were required to isolate policy changes and protect +the includer. While some scripts intend to affect the policies of their +includer, most do not. In CMake 2.6.3 and above, :command:`include` and +:command:`find_package` by default ``PUSH`` and ``POP`` an entry on +the policy stack around an included +script, but provide a ``NO_POLICY_SCOPE`` option to disable it. This +policy determines whether or not to imply ``NO_POLICY_SCOPE`` for +compatibility. The ``OLD`` behavior for this policy is to imply +``NO_POLICY_SCOPE`` for :command:`include` and :command:`find_package` commands. +The ``NEW`` behavior for this policy is to allow the commands to do +their default cmake_policy ``PUSH`` and ``POP``. + +This policy was introduced in CMake version 2.6.3. 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 |
