# CMAKE_POLICY_DEFAULT_CMP<NNNN>

Default for CMake Policy `CMP<NNNN>` when it is otherwise left unset.

Commands `cmake_minimum_required(VERSION)` and `cmake_policy(VERSION)` by default leave policies introduced after the given version unset. Set `CMAKE_POLICY_DEFAULT_CMP<NNNN>` to `OLD` or `NEW` to specify the default for policy `CMP<NNNN>`, where `<NNNN>` is the policy number.

This variable should not be set by a project in CMake code; use `cmake_policy(SET)` instead. Users running CMake may set this variable in the cache (e.g. `-DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>`) to set a policy not otherwise set by the project. Set to `OLD` to quiet a policy warning while using old behavior or to `NEW` to try building the project with new behavior.
