Can't set up Mingw for OxeFMSynth + scaling issues?

SOLVED: [Oxe Synth is really small, and is hard to use, especially for a beginner. I wish, if there were a drop-down option, or maybe for now, a bigger GUI. Is it possible to do that?]

And would there be a guide on how to build for Windows? I think that I have mingw - which comes preinstalled with Git Bash, or Railsinstaller. What next? Because maybe, I could figure it for myself?

No definitely install mingw separately, then try.

Also, check out #28

@mkruselj thanks for highlighting the issue. I've tried Mingw from Win-build, as well as Cygwin, but it wasn't working. Finally, tried the Mingw-w64, and the environment seems to be working well, except for the build error.

Just realized that this works without any popups in Git Bash, so probably, this is the Makefile not configured properly for Windows.
uname -s is a UNIX command, I guess.
