CMAKE_POLICY_WARNING_CMP<NNNN>

Explicitly enable or disable the warning when CMake Policy CMP<NNNN> has not been set explicitly by :command:cmake_policy or implicitly by :command:cmake_minimum_required. This is meaningful only for the policies that do not warn by default:

  • CMAKE_POLICY_WARNING_CMP0025 controlled the warning for policy :policy:CMP0025 in CMake versions before 4.0.
  • CMAKE_POLICY_WARNING_CMP0047 controlled the warning for policy :policy:CMP0047 in CMake versions before 4.0.
  • CMAKE_POLICY_WARNING_CMP0056 controlled the warning for policy :policy:CMP0056 in CMake versions before 4.0.
  • CMAKE_POLICY_WARNING_CMP0060 controlled the warning for policy :policy:CMP0060 in CMake versions before 4.0.
  • CMAKE_POLICY_WARNING_CMP0065 controlled the warning for policy :policy:CMP0065 in CMake versions before 4.0.
  • 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.
  • CMAKE_POLICY_WARNING_CMP0089 controls the warning for policy :policy:CMP0089.
  • CMAKE_POLICY_WARNING_CMP0102 controls the warning for policy :policy:CMP0102.
  • CMAKE_POLICY_WARNING_CMP0112 controls the warning for policy :policy:CMP0112.
  • CMAKE_POLICY_WARNING_CMP0116 controls the warning for policy :policy:CMP0116.
  • CMAKE_POLICY_WARNING_CMP0126 controls the warning for policy :policy:CMP0126.
  • CMAKE_POLICY_WARNING_CMP0128 controls the warning for policy :policy:CMP0128.
  • CMAKE_POLICY_WARNING_CMP0129 controls the warning for policy :policy:CMP0129.
  • CMAKE_POLICY_WARNING_CMP0133 controls the warning for policy :policy:CMP0133.
  • CMAKE_POLICY_WARNING_CMP0172 controls the warning for policy :policy:CMP0172.
  • CMAKE_POLICY_WARNING_CMP0206 controls the warning for policy :policy:CMP0206.

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 :option:--debug-output <cmake --debug-output>, :option:--trace <cmake --trace>, or :option:--trace-expand <cmake --trace-expand> option will also enable the warning.
