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. |
