It is actually normal that this is empty because pkg-config is built to look within its $prefix/lib/pkgconfig automatically. So, it is very strange that it could not see the .pc file in that location. Usually, people only set PKG_CONFIG_PATH when they are installing things to non-standard locations like /opt or $HOME.
