Automatic git tag appended to build is sometimes one commit behind

I thought we fixed that (and the fix is present in the code) but it still doesn't work all the time

Yeah I noticed this as well. It seems that the git tag is put into the generated files in the build dir, but updating those files doesn't trigger a re-build of the main binary. I poked at it for a little while and didn't see the cause.

You can make it not work by tagging a commit, then building. It will use the tag of the previous commit. But if you make a new commit, it will use the new tag.

When I need a certain tag, e.g. for a release, a clean build fixes it (though if you do make clean you have to also rebuild the api-symbol list with make new-api-sym-list && make. Since CI uses clean builds, it's not a problem for tagging releases, just for locally keeping track of versions.

The last line in log above is just printing a cmake variable so even that on is not set correctly
