Resources issue with glib-compile-resources

[phodina]

Hi Guix,

I'm struggling to build this package (patch provided below)
and would like to ask for your ideas.

The issue is that in Makefile we call glib-compile-resources
to compile the resources. However, the path needs to be substituted
otherwise the resources are not found when the app is launched.

But by substituting the location the build phase fails as the
glib-compile-resources command looks for the resources in the
/gnu/store/xxxxx where the files are not yet present.

The only solution I come up with is to install those files there
before the build stage.

What do you think?
