| The CMake variable :variable:`CMAKE_FIND_ROOT_PATH` specifies one or more | |
| directories to be prepended to all other search directories. This | |
| effectively "re-roots" the entire search under given locations. | |
| Paths which are descendants of the :variable:`CMAKE_STAGING_PREFIX` are excluded | |
| from this re-rooting, because that variable is always a path on the host system. | |
| By default the :variable:`CMAKE_FIND_ROOT_PATH` is empty. | |
| The :variable:`CMAKE_SYSROOT` variable can also be used to specify exactly one | |
| directory to use as a prefix. Setting :variable:`CMAKE_SYSROOT` also has other | |
| effects. See the documentation for that variable for more. | |
| These variables are especially useful when cross-compiling to | |
| point to the root directory of the target environment and CMake will | |
| search there too. By default at first the directories listed in | |
| :variable:`CMAKE_FIND_ROOT_PATH` are searched, then the :variable:`CMAKE_SYSROOT` | |
| directory is searched, and then the non-rooted directories will be | |
| searched. The default behavior can be adjusted by setting | |
| |CMAKE_FIND_ROOT_PATH_MODE_XXX|. This behavior can be manually | |
| overridden on a per-call basis using options: | |
| ``CMAKE_FIND_ROOT_PATH_BOTH`` | |
| Search in the order described above. | |
| ``NO_CMAKE_FIND_ROOT_PATH`` | |
| Do not use the :variable:`CMAKE_FIND_ROOT_PATH` variable. | |
| ``ONLY_CMAKE_FIND_ROOT_PATH`` | |
| Search only the re-rooted directories and directories below | |
| :variable:`CMAKE_STAGING_PREFIX`. | |
