Is there somewhere to get a copy of the GLX header and library files on Windows? All the links I find keep saying to use apt-get, yum, etc.

Yeah, that's the one. I was hoping for precompiled... but I guess that's fine. In case you were wondering, the purpose was so that I could build all three versions of a program without changing computers (just to see if the code compiles correctly, I know it won't run). Currently I get all these linking errors because, of course, there's no library to link to.
