Comment:
Point against building from git is that we lose caching, so every build has to repeat the huge download. The reason we do it for `ardour` is because upstream deletes their pre-generated tarballs, but I still greatly dislike it...

IMO let's move the PR forward by pulling from git, then ponder more from there.

Please do like it's done in `ardour`, where we checkout a specific commit.
