[SOLVED] How to compile NetRadiant in Windows (SOLVED)

Hi. I am having difficulties compiling NetRadiant do to an unending list of unmet dependencies. I installed all of the dependencies I could find, but am unable to find the rest of them. Here is the output from Make inside of cygwin:

EDIT: I solved the problem by porting the Linux files into Windows (yes; I was able to just copy over the compiled files), and it worked (no need for Cygwin)!
The problem is; I am unable to find it. I have a Linux machine (that has a bad graphics card) that I might be able to use to compile it and than somehow port the Xonotic-related files to Windows (if that's possible, because it will compile it in Linux format)
