[cairo] cairo iOs

[Whiteunicorn Whiteunicorn]

Hello
My goal is to compile cairo (maybe cairomm) for iOs in a bare minimum form, so that i can convert png (binary black and white, no gray tones) to svg and nothing more. I don't need other kind of support from it such as rendering based on hardware acceleration and such. The png files are so tiny that i can live with quartz graphics. With that said I was wondering if I could get some help/tips on doing that. 
My current effort was to attempt including the source cairo files into a iOs library project and try to compile that, but even after disabling everything unnecessary (xlib, etc) I've got stuck with gl support. Disabling this as well results in a compilation error 
i.e. # error Cairo was not compiled with support for the GL backend
