CMAKE_FIND_ROOT_PATH_MODE_PACKAGE

This variable controls whether the CMAKE_FIND_ROOT_PATH and CMAKE_SYSROOT are used by find_package().

If set to ONLY, then only the roots in CMAKE_FIND_ROOT_PATH will be searched. If set to NEVER, then the roots in 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 CMAKE_FIND_ROOT_PATH will be searched.
