+The girdir in the .pc file is defined like this:
+
+${pc_sysrootdir}/${datadir}/gir-1.0
+
+If you replace pc_sysrootdir with a /, and datadir with /usr/share, you end
+up with ///usr/share/gir-1.0, which cmake treats as a network path, and
+breaks when used with destdir
+
+So replace a useless substitute (we don't use a non-standard prefix) with
+a useful one
