CMAKE_POLICY_WARNING_CMP ------------------------------ Explicitly enable or disable the warning when CMake Policy ``CMP`` 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`. * ``CMAKE_POLICY_WARNING_CMP0082`` controls the warning for policy :policy:`CMP0082`. 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=ON``). Alternatively, running :manual:`cmake(1)` with the ``--debug-output``, ``--trace``, or ``--trace-expand`` option will also enable the warning.
