Doesn't work with msys2: ln: failed to create symbolic link '/usr/local/bin/gcc': No such file or directory

I don't know much about Windows but I am using msys2 in order to compile in Windows. I think that it's supposed to make it easier to build Windows programs using a linux-like platform.

Anyway, it isn't working with this ccache. msys2 installs its own shell and all commands after msys2 are installed use that one. You can see that each step in my CI has a shell specified:

But the cache isn't using that shell and I don't know why. Maybe that is what causes the problem?

We'd like to see the msys2 shell in use there instead of the one provided by git.

Looks like /usr/local/bin doesn't exist yet on the runner. Should definitely be added.

Regardless, you should just install ccache from the MSYS2 repository instead.
