[gi-glib-2.0.26] Cannot find GI repositories on Apple Silicon Mac brew

[yobson]

Hello!

The Problem

When building an empty project with gi-gtk and haskell-gi-base, on an apple silicon Mac, you will run into the following issue:

Linking /Users/jameshobson/Documents/Haskell/gtk4-elm/dist-newstyle/tmp/src-77102/gi-glib-2.0.26/dist/setup/setup ...
Did not find a GI repository for GLib-2.0 in ["/usr/local/share/gir-1.0","/usr/share/gir-1.0"].
CallStack (from HasCallStack):
  error, called at lib/Data/GI/GIR/Repository.hs:89:20 in hskll-g-0.26.1-bd0bfefb:Data.GI.GIR.Repository

This is because brew installs into /opt/homebrew on the apple silicon platforms. It used to install into /usr/local

Temporary Workaround

I have made a simple symlink with sudo ln -s /opt/homebrew/share/gir-1.0 /usr/local/share/. and it appears to be building fine. I'm sure there was a less hacky fix I could have done with an environment variable, but I didn't investigate into much!

Thanks for the report!

I have added a workaround in e095096 for this. Do you think you could test that version (removing the symlinks you added) and see if that works for you? If so I'll upload a new version to hackage with the fix.

Many thanks in advance!
