    # a few things:
    #   * add `includes` parameter: it will add `-isystem path/to/slog_cc` flag
    #     to a compiler that will make all files under slog_cc/ dir will be
    #     available to include with angle brackets,
    #     e.g. `#include <slog_cc/slog.h>`.
    #   * add `strip_include_prefix` to make files of C++ slog subdir exposed.
    #   * add `include_prefix` to put all C++ slog include files behind slog_cc
    #     prefix dir.
    # Note: it sounds like using `strip_include_prefix` and `include_prefix`
    # with same value doesn't make sense, but if we remove there params user
    # project will not be able to see slog .h files for some reason.
