    # Example of usage

    Add into your CMakeLists.txt the next lines:

    # --------------------------------------------------------------------------

    # Include 'ino_meta_lib.cmake' file - to be able to call 'load_ino_meta_lib()'
    include(/path/to/ino_meta_lib/ino_meta_lib.cmake)

    load_ino_meta_lib(INO_META_LIB_INCLUDE_DIRECTORIES INO_META_LIB_HEADERS INO_META_LIB_SOURCES)

    add_executable( <YOUR_EXECUTABLE>
        # ...
        ${INO_META_LIB_HEADERS} ${INO_META_LIB_SOURCES}
    )

    # Add 'ino_meta_lib' includes into search pathes
    target_include_directories( <YOUR_EXECUTABLE> ${INO_META_LIB_INCLUDE_DIRECTORIES} )

    # --------------------------------------------------------------------------
]]

# directory of **this** file, otherwise (if use 'CMAKE_CURRENT_LIST_DIR' inside
# of function) it will contain path, related to file where function called).
