Integrates Github Actions which is much much faster than AppVeyor in all areas, and even supports multiple workflows instead of forcing everything into just one workflow like AppVeyor does. Plus we get 20 parallel builds that nearly instantly finish, which results in much faster feedback without having to run our own Jenkins CI.
The builder and packager scripts have been adjusted to add support for both Windows and Linux, and both AppVeyor and Github Actions. Additionally to that, the builder script now correctly executes x32 and x64 steps in a chain, instead of waiting for the other architecture to finish first. This further reduces build times.
By configuring and building 32-bit and 64-bit builds in parallel we can save massive amounts of time usually spent just waiting on other resources while the CPU is idle. On AppVeyor, this results in a roughly 50% lower build time, ensuring that builds can complete faster than before.
Artifacts have been reduced to only be created for tagged releases, which also reduces total build time. Additionally the notifications have been reduced to only happen when the build status changes, as there is no reason to notify about things that did not change the status.
This includes support for included, referenced, packaged and downloaded obs-studio libraries, cppcheck, packaging using cpack, 7z, zip or InnoSetup and more.
