> We could install and enable ccache on macOS Github Actions jobs. It would probably speed up a lot of builds.
> Apparently ccache is available on Homebrew.  Here is an example using it:
> https://github.com/azerothcore/azerothcore-wotlk/blob/master/.github/workflows/macos_build.yml#L26-L33
> {code:yaml}
>       - name: Cache
>         uses: actions/cache@v2
>         with:
>           path: ~/Library/Caches/ccache
>           key: ccache:${{ matrix.os }}:${{ github.ref }}:${{ github.sha }}
>           restore-keys: |
>             ccache:${{ matrix.os }}:${{ github.ref }}
>             ccache:${{ matrix.os }}
> {code}
