This comes from PR 227097
Maintainer sent update to 2.12.6 but while processing this PR, 2.12.8 came out
so I went directly for that one.
Maintainer will be notified in the PR.
Changes:
- Update to 2.12.8
- USE_GITHUB since this release is only in GH and not in SF
- Add LICENSE according to project's site (no license file is provided)
- Use DISTVERSION instead of PORTVERSION
- Flavorize port and make qt5 default (as in the old version)
