CMake 4.0 dropped support for projects with a minimum required version
below 3.5. libarchive, as well as possibly other dependencies, had older
versions set so they now fail to build.
GitHub Actions and MSYS2 were very quick to update their CMake version
and there isn't a tagged vcpkg release with a fix for libarchive yet, so
we will use a specific commit for now.
* Use macOS 14 M1-based runners for macOS CI
* Hopefully make the universal build erroring not fail the build (does sometimes with delete-artifact)
* Update vcpkg version
* Integrate support for building with dependencies from vcpkg
Configure the build using -DUSE_VCPKG=ON to use vcpkg. By default
recommended triplets targeting the OS versions official builds support
are used. You can opt out of this with -DUSE_RECOMMENDED_TRIPLETS=OFF.
* Add the vcpkg manifest
* Fetch vcpkg with FetchContent if we don't have it
* macOS cross compiling fixes
- can't use the x86_64 one as host triplet on arm64 because building Qt
fails for whatever reason. Because of course it does :D
- vcpkg doesn't always like periods in triplet names so removed those
* x86_64 macOS should also use its recommended target when building arm64 builds
