Grab a version nicely from Gitlab (works in CI or non-CI)

pkgversion

  # Check if we can find a tag otherwise specifically fetch tags
  git describe --tags >/dev/null 2>&1 || git fetch --tags
  # Set our package version correctly
  PKGVERSION="$(git describe --tags 2>/dev/null)"
  # If our package version couldn't be set this way then use Gitlab CI
  if [ -z "$PKGVERSION" -a -n "$CI_COMMIT_SHORT_SHA" -a -n "$CI_PIPELINE_IID" -a -n "$CI_JOB_TOKEN" ]; then
