Suggestions how? A common approach for this is to either use a pkgconfig file or to provide a public Autoconf macro in a separate m4 file to be installed in /usr/share/aclocal. That macro then encapsulates the logic to link against your library for third-party software. This macro could provide a --with-included-libFOO switch for such embedded cases. Hope that helps.
