With that said I was wondering if I could get some help/tips on doing that. 

You do know that cairo cannot convert PNG files to SVG, right?

So, you are not using cairo's Makefile, but instead directly add cairo's
C files to your project, right?

Please look at src/Makefile.sources [0]. You do not need to add all
source files, but only those for the enabled backends (and those listed
under cairo_sources). So, in your case, all the files listed under
cairo_gl_sources [1] are not needed.

Cheers,
Uli

doing it wrong.
