# We do this via a custom command that re-invokes a cmake script because we need the DEPENDS on .git/index so that we will re-run it (to regenerate the commit tag in the version) whenever the current commit changes. If we used a configure_file directly here, it would only re-run when something else causes cmake to re-run.
