No, please don't. CMAKE_FIND_ROOT_PATH is intended for cross-compiling, to tell cmake where the root of the target file system is located. Use CMAKE_PREFIX_PATH instead. It can contain a list of directories, and find_program(), find_file(), find_path(), find_package() and find_library() append bin/, include/ and lib/ respectively to each of the directories listed there. The directories resulting from CMAKE_PREFIX_PATH are checked before all PATHS and HINTS directories. E.g. if you have stuff inside /your/local/install/dir and /some/other/dir, do $ export CMAKE_PREFIX_PATH=/your/local/install/dir:/some/other/dir $ cmake ...args or set it directly as a cmake variable within your CMakeLists.txt.
