| Support new :command:`if` IN_LIST operator. | |
| CMake 3.3 adds support for the new IN_LIST operator. | |
| The ``OLD`` behavior for this policy is to ignore the IN_LIST operator. | |
| The ``NEW`` behavior is to interpret the IN_LIST operator. | |
| This policy was introduced in CMake version 3.3. | |
| CMake version |release| warns when the policy is not set and uses | |
| ``OLD`` behavior. Use the :command:`cmake_policy` command to set | |
| it to ``OLD`` or ``NEW`` explicitly. | |
