Hm. There actually already is the mingw ccache installed. The images for mingw and msvc used to be separate (for startup performance when using containers), but we just merged them. So it might be easiest to just explicitly use the ccache from there (also an explicit path might be faster). Could you check if that's fast? If not, we can just install the binaries distributed by the project, it's just more work to keep up2date that way.
