Why is gitlab CI failing for all packages except for Windows MinGW-w64 Package ?

edit

If I look at the most recent pipeline for your pull request - which, rather than pipelines on your own repository, are what matter for upstreaming - the commit check job failed with

This is because you must, at minimum, have a comment header that specifies a license for the code. It should probably also include a copyright notice to go along with the license, plus some other information, e.g.:

Try adding that to your source files (all three of them) in your personal GitHub repository; that should trigger a new build of the pull request.

(And ask further questions on your pull request, rather than here, so that the issues can be directly tracked on the pull request.)
