- CMAKE_POLICY_DEFAULT_CMP<NNNN>
- ------------------------------
- Default for CMake Policy ``CMP<NNNN>`` when it is otherwise left unset.
- Commands :command:`cmake_minimum_required(VERSION)` and
- :command:`cmake_policy(VERSION)` by default leave policies introduced after
- the given version unset. Set ``CMAKE_POLICY_DEFAULT_CMP<NNNN>`` to ``OLD``
- or ``NEW`` to specify the default for policy ``CMP<NNNN>``, where ``<NNNN>``
- is the policy number.
- This variable should not be set by a project in CMake code; use
- :command:`cmake_policy(SET)` instead. Users running CMake may set this
- variable in the cache (e.g. ``-DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>``)
- to set a policy not otherwise set by the project. Set to ``OLD`` to quiet a
- policy warning while using old behavior or to ``NEW`` to try building the
- project with new behavior.
