As =E5=AE=8B=E6=96=87=E6=AD=A6 suggests, glib-or-gtk-build-system may solve=
 the problem if we
add =E2=80=98hicolor-icon-theme=E2=80=99 to the inputs, because it would au=
tomatically
add it to $XDG_DATA_DIRS.  Wouldn=E2=80=99t it?

Currently things like Evince, for instance, do find their icons.
GIMP and Inkscape are fine too, but I think they use slightly different
mechanisms.

Thanks,
