| This variable controls whether the :variable:`CMAKE_FIND_ROOT_PATH` and | |
| :variable:`CMAKE_SYSROOT` are used by |FIND_XXX|. | |
| If set to ``ONLY``, then only the roots in :variable:`CMAKE_FIND_ROOT_PATH` | |
| will be searched. If set to ``NEVER``, then the roots in | |
| :variable:`CMAKE_FIND_ROOT_PATH` will be ignored and only the host system | |
| root will be used. If set to ``BOTH``, then the host system paths and the | |
| paths in :variable:`CMAKE_FIND_ROOT_PATH` will be searched. |
