- Added fullMode input in workflow_dispatch
- Take decision whether to build either in debug or release mode and if to build for all python versions according to the commit message patterns
- Set proper artifact names
- Removed not needed steps
- Compacted some steps in order to leverage more the matrix feature
- Bumped cibuildwheel action to 2.22.0
- Run actual regress tests in place of sample scripts
- Specify optional test install in pyproject.toml with proper requirements
- Derive package version from git tags
- Add GENERATORS env var support in setup.py to specify cmake generator and minor refactoring
- Minor cleanup/refactoring for the regress test suite
- Marked some regress tests with skipIf to skip them in case of old python versions
- Marked some failing regress tests to be checked with skipIf
