gobject-introspection .gir search path

[Ludovic Courtès]

While trying to package librsvg, I stumbled upon this:

--8<---------------cut here---------------start------------->8---
Couldn't find include 'GdkPixbuf-2.0.gir' (search path: ['.', 'gir-1.0', 
'/gnu/store/xdd5ndl01700w23z206nc36nqg96z94v-gobject-introspection-1.38.0/share/gir-1.0',
 '/usr/share/gir-1.0', 
'/gnu/store/xdd5ndl01700w23z206nc36nqg96z94v-gobject-introspection-1.38.0/share/gir-1.0'])
/gnu/store/xdd5ndl01700w23z206nc36nqg96z94v-gobject-introspection-1.38.0/share/gobject-introspection-1.0/Makefile.introspection:153:
 recipe for target 'Rsvg-2.0.gir' failed
make[2]: *** [Rsvg-2.0.gir] Error 1
--8<---------------cut here---------------end--------------->8---

Do you remember if the gobject-introspection “scanner” had a way to
specify a search path, like an env. var.?

Otherwise, how can we make sure that the .girs of inputs are visible?

TIA.  :-)
