Comment (by eighthave):
Ok, little bits of progress to convey. I now have libwebrtc repeatably
building in gitlab-ci. It probably downloads 10+ gigs of stuff, but it
finishes in well under an hour, so it fits fine within the gitlab-ci
limits. I think I also have the pkgconfig stuff sorted out. Based on the
missing symbols, it looks pretty close, since there are only a few:
