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. By using CMAKE_FIND_ROOT_PATH_BOTH +the search order will be as described above. If +NO_CMAKE_FIND_ROOT_PATH is used then :variable:`CMAKE_FIND_ROOT_PATH` will not be +used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted +directories and directories below :variable:`CMAKE_STAGING_PREFIX` will be searched. |
