Re: [BUG] Clones from local repositories do not work correctly under Windows

Hi all,

In Cerbero, we use cygpath or a bespoke conversion mechanism, depending
on availability:

https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/main/cerbero/utils/__init__.py#L142-149

I'm not sure if there's a function in MSYS2's libc exposing that.
