- CMAKE_POLICY_WARNING_CMP<NNNN>
- ------------------------------
- Explicitly enable or disable the warning when CMake Policy ``CMP<NNNN>``
- is not set. This is meaningful only for the few policies that do not
- warn by default:
- * ``CMAKE_POLICY_WARNING_CMP0025`` controls the warning for
- policy :policy:`CMP0025`.
- * ``CMAKE_POLICY_WARNING_CMP0047`` controls the warning for
- policy :policy:`CMP0047`.
- * ``CMAKE_POLICY_WARNING_CMP0056`` controls the warning for
- policy :policy:`CMP0056`.
- * ``CMAKE_POLICY_WARNING_CMP0060`` controls the warning for
- policy :policy:`CMP0060`.
- * ``CMAKE_POLICY_WARNING_CMP0065`` controls the warning for
- policy :policy:`CMP0065`.
- * ``CMAKE_POLICY_WARNING_CMP0066`` controls the warning for
- policy :policy:`CMP0066`.
- * ``CMAKE_POLICY_WARNING_CMP0067`` controls the warning for
- policy :policy:`CMP0067`.
- This variable should not be set by a project in CMake code. Project
- developers running CMake may set this variable in their cache to
- enable the warning (e.g. ``-DCMAKE_POLICY_WARNING_CMP<NNNN>=ON``).
- Alternatively, running :manual:`cmake(1)` with the ``--debug-output``,
- ``--trace``, or ``--trace-expand`` option will also enable the warning.
