cygpath (if it's available, which it is on MSYS2 and Cygwin at least)
can convert between Windows/UNIX style paths. See
https://git.videolan.org/?p=x264.git;a=blob;f=tools/msvsdepend.sh

I would opt for converting everything to UNIX-style paths instead of
Windows-style paths. IIRC some system had issues with the latter in
certain scenarios.
