autobuild.yml

# This file builds the source and produces artifacts for every supported platform.
# For release tags it creates a Github release and uploads the binaries to that releases.
# The builds are instrumented with CodeQL.

# see analyse_git_reference.py for implementation of the logic:
#     for every push to a branch starting with "autobuild": (can be used during development for tighter supervision of builds)
#          - do CodeQl while building for every platform
#          - publish the created binaries/packs only as artifacts/appendix of the github-action-run (not as release), and only retain those files for limited period
#     for every pull-request to main:
#          - do CodeQl while building for every platform
#          - publish the created binaries/packs only as artifacts/appendix of the github-action-run (not as release), and only retain those files for limited period
#     for every tag that starts with 'r' and has an arbitrary suffix (e.g. beta1, rc1, etc.)
#          - do CodeQl while building for every platform
#          - publish the created binaries/packs only as artifacts/appendix as a prerelease
#     for every tag that starts with 'r' and does not have any suffix:
#          - do CodeQl while building for every platform
#          - publish the created binaries/packs only as artifacts/appendix as a release
