| # - Returns a version string from Git | ||
| # | ||
| # These functions force a re-configure on each git commit so that you can | ||
| # trust the values of the variables in your build system. | ||
| # | ||
| # get_git_head_revision(<refspecvar> <hashvar> [<additional arguments to git describe> ...]) | ||
| # | ||
| # Returns the refspec and sha hash of the current head revision | ||
| # | ||
| # git_describe(<var> [<additional arguments to git describe> ...]) | ||
| # | ||
| # Returns the results of git describe on the source tree, and adjusting | ||
| # the output so that it tests false if an error occurs. | ||
| # | ||
| # git_get_exact_tag(<var> [<additional arguments to git describe> ...]) | ||
| # | ||
| # Returns the results of git describe --exact-match on the source tree, | ||
| # and adjusting the output so that it tests false if there was no exact | ||
| # matching tag. | ||
| # | ||
| # git_local_changes(<var>) | ||
| # | ||
| # Returns either "CLEAN" or "DIRTY" with respect to uncommitted changes. | ||
| # Uses the return code of "git diff-index --quiet HEAD --". | ||
| # Does not regard untracked files. | ||
| # | ||
| # Requires CMake 2.6 or newer (uses the 'function' command) | ||
