# We depend on g-ir-scanner from gobject-introspection-1.0 to scan our source
# to build GIR files. We then use gi-compile-repository from the local build
# tree to build the typelibs (rather than using g-ir-compiler from
# gobject-introspection). However, we use Meson’s gnome.generate_gir() function,
# which adds a hard dependency on gobject-introspection-1.0, so we’d better
# check for that here.
