PATH
mode is legacy alias forDIRECTORY
mode (needed only for CMake <= 2.8.11):https://cmake.org/cmake/help/latest/command/get_filename_component.html
By the way,
get_filename_component()
command itself is deprecated in favor ofcmake_path()
command, butcmake_path()
command was introduced in CMake 3.20, which is too new for Protobuf, which currently requires CMake >= 3.5.
