Crosscompiling: adding a library

Spent the day trying different things out to no avail.

My goal is to cross-compile ioq3 on linux (wheezy), for Windows target.

I got it all running pretty well, except I need to add SDL_ttf and freetype (freetype is needed by SDL_ttf).

What would be the proper way? What do I need to modify in the Makefile, and where do I need to drop libs (which version of libs, ? .dll, .a, .dll.a ? confused

Also, what would be the proper way to build it all statically ?

Thanks in advance. The Makefile is cryptic, really (or I am newb, or both).
