| CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE_BEFORE | |
| ------------------------------------------- | |
| A CMake language file or module to be included as the first step of any | |
| :command:`project` command calls that specify ``<PROJECT-NAME>`` as the project | |
| name. This is intended for injecting custom code into project builds without | |
| modifying their source. | |
| See also the :variable:`CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE`, | |
| :variable:`CMAKE_PROJECT_INCLUDE` and | |
| :variable:`CMAKE_PROJECT_INCLUDE_BEFORE` variables. |
