dnl Check for glib. This differs from other library checks in that
dnl Emacs need not link to glib unless some other library is already
dnl linking to glib. Although glib provides no facilities that Emacs
dnl needs for its own purposes, when glib is present Emacs needs to
dnl use primitives like g_main_context_query to avoid clashing with
dnl glib at a low level.
