CMAKE_POLICY_WARNING_CMP<NNNN>

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

• CMAKE_POLICY_WARNING_CMP0025 controls the warning for policy CMP0025.

• CMAKE_POLICY_WARNING_CMP0047 controls the warning for policy CMP0047.

• CMAKE_POLICY_WARNING_CMP0056 controls the warning for policy CMP0056.

• CMAKE_POLICY_WARNING_CMP0060 controls the warning for policy CMP0060.

• CMAKE_POLICY_WARNING_CMP0065 controls the warning for policy CMP0065.

• CMAKE_POLICY_WARNING_CMP0066 controls the warning for policy CMP0066.

• CMAKE_POLICY_WARNING_CMP0067 controls the warning for policy CMP0067.

• CMAKE_POLICY_WARNING_CMP0082 controls the warning for policy CMP0082.

• CMAKE_POLICY_WARNING_CMP0089 controls the warning for policy CMP0089.

• CMAKE_POLICY_WARNING_CMP0102 controls the warning for policy CMP0102.

• CMAKE_POLICY_WARNING_CMP0112 controls the warning for policy CMP0112.

• CMAKE_POLICY_WARNING_CMP0116 controls the warning for policy CMP0116.

• CMAKE_POLICY_WARNING_CMP0126 controls the warning for policy CMP0126.

• CMAKE_POLICY_WARNING_CMP0128 controls the warning for policy CMP0128.

• CMAKE_POLICY_WARNING_CMP0129 controls the warning for policy CMP0129.

• CMAKE_POLICY_WARNING_CMP0133 controls the warning for policy CMP0133.

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 cmake(1) with the --debug-output, --trace, or --trace-expand option will also enable the warning.
