Edit #3:

Did a fresh install of cygwin, everything worked fine, however, now it can't find my webcam, which is an essential part of the project. Is there some sort of flag i can pass to make cygwin use mingw/windows (which I assume isn't happening)? With a configure script, I understand I could use a --target= flag, but I'm not sure how to approach this in cygwin.
