Document how to use GetGitRevisionDescription "offline" about cmake-modules HOT 3 OPEN

Yeah, that would be a good thing. I'm not sure there's a single best way, especially since projects tend to use a git archive as their release tarball, which leaves little room to inject a version file. Probably best approach is to include a version file, but ignore it if you find out there's a git repo?

Not the same thing in my mind, the git archive output is useless as far as I'm concerned. It's neither a Git repo with any history or context nor a proper source release with prep work done. The only use cases I care about are actual Git repositories (with history & tags) and generated release tarballs which can include whatever generated resources are needed to make the build function without the repo history. An exact version string is part of that.

By the way the above linked project workflow does include one way of doing this for by stashing a file when building cmake source packages. This issue was before I worked out a way ... and I don't know if my solution is a very elegant one, CMake might have an easier way to go about it than what I did.
