[nonperforming]

https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/
Update: Node12 has been removed and will now run on Node16 https://github.blog/changelog/2023-07-17-github-actions-removal-of-node12-from-the-actions-runner/

CMake Build is no longer being updated so I made Actions directly invoke CMake from shell

Edit: Fixes #1047

Windows:
SDL 2.0 not found, set ENV{SDL2DIR} to point to SDL 2.0

Which is strange because we have
sdl2:x86-windows-static
included in vcpkg_x86-windows.txt

Mac:
Ninja not found?
Running cmake -G in my console produces
...
Ninja = Generates build.ninja files.
...
And Ninja tool is installed by default in macOS runners??

Could you remove shell: bash and try again?

The backtick character for line continuation is specific to PowerShell. PowerShell uses it in place of the backslash symbol to avoid issues with Windows paths. And apparently ${{ runner.workspace }} includes backslashes.

I was mistaking AppVeyor for GitHub Actions here. GHA does not package Ninja with their runners
