XCode 4 Relative #include paths in search?

I'm trying to port over a project I initially wrote in Windows to OS X and am having some difficulty with the header search paths.

I've used user search paths to include by source folder "project/src/core/" Под ядром у меня есть, например: "проекты / src / core / sys / sys_sdl.h" который пытается включить "проекты / src / core / render / opengl_render.h" with the directive:

#include "render/opengl_render.h"

I've tried tons of different options, but I can't get seem to get Xcode to find the file unless I change it to "../render/opengl_render.h"

Is there something I'm missing here in the settings to get it to recognize relative paths to the header search paths?
