[racket] How to compile C libraries that use Cairo?

Success! I have now managed to build libcairo from scratch.
By luck I fell over:

http://cairographics.org/end_to_end_build_for_mac_os_x/

which I was able to follow without too many problems.

A few notes, white I can remember them:

1. The section on setting up the environment variables.
    I used these flags (The oldest SDK I had was 10.6):

BuildDir=/Users/soegaard/BuildCairo

ZLIBLIB=/Users/soegaard/BuildCairo/lib

   LDFLAGS=-isysroot /Developer/SDKs/MacOSX10.6.sdk
-L/Users/soegaard/BuildCairo/lib -arch x86_64 -lz

CPPFLAGS=-I/Users/soegaard/BuildCairo/include/

CFLAGS=-Os -isysroot /Developer/SDKs/MacOSX10.6.sdk
-I/Users/soegaard/BuildCairo/include/ -arch x86_64

CC=/usr/bin/gcc

Note that:

/usr/bin/gcc --version
Configured with:
--prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix


2. In order to build libpng I had to build zlib first. Note that to
link with zlib, the linker needs the flag -lz


Tomorrow I'll try to built libpoppler and librsvg using the same principle.
