I still haven't finished this, but while working on it I realized that I should have suggested a work around. You can create a setup.cfg file in the directory containing your library setup.py file. This ConfigParser-style configuration file should have a build_ext section containing the options you want: [build_ext] include-dirs = /foo/include This is actually what the develop recipe will do behind the scenes.
