| .. versionadded:: 4.2 |
| |
| :variable:`CMAKE_PARENT_LIST_FILE` is not defined in ``CMakeLists.txt``. |
| |
| CMake 4.1 and below defined ``CMAKE_PARENT_LIST_FILE`` when processing |
| a ``CMakeLists.txt`` even though there is no parent file. CMake 4.2 |
| and above prefer to not define ``CMAKE_PARENT_LIST_FILE``. This policy |
| provides compatibility for projects that accidentally relied on the |
| old behavior. |
| |
| The ``OLD`` behavior for this policy is to set |
| :variable:`CMAKE_PARENT_LIST_FILE` to :variable:`CMAKE_CURRENT_LIST_FILE` |
| when processing a ``CMakeLists.txt``. The ``NEW`` behavior for this policy |
| is to not set :variable:`CMAKE_PARENT_LIST_FILE`. |
