This PR does a few things:
- Updates ares to create macOS builds with the latest SDK. After
65264090b0
there are no longer any outstanding issues doing so. Importantly, we use
Xcode 15.2, since prior versions have issues with weak linking.
- Adds `macos-compat` to CI as a compatibility build that maintains
macOS 10.9 to 10.13 compatibility. The `macos-latest` runner will target
10.13 and above. The only difference with this build is the SDK version
used to build it (Xcode 13.4); macOS weak linking handles the rest.
- Increments the MoltenVK version to 1.2.7. The version ares was
building required a Python library `distutils` that is no longer
trivially available with newer Python versions.
- Refactors the `xcode-select` usage reserved for GitHub Actions out of
the SDL script and up to the top level, before any dependency scripts
are run. This is just tidying up.
- Improves the librashader build script warning to specify that you need
to add a target with the nightly toolchain to build librashader (from
@rasky)
- Unbreaks the build.
This PR has been tested and verified to build in a local branch, but to
be safe, it would probably be good to run it here as well.
