the bindings generator (generator.lua) accepts a -i flag, which tells
the headers it must include.
CMakeList.txt is qt specific and uses this flag in the way you
describe. If you bind other libraries you have to supply the correct
include files with the -i option. I have just committed the
possibility of using a header with <...> syntax.
