| 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`. |
| |
| 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`` |
| or ``--trace`` option will also enable the warning. |
