I am trying to set up `GPUImage` in a project but I am not able to track down why I'm getting the error: "GPUImage.h" not found. I have added the framework, setup the target dependency, added the Header Search path as: framework, and added other linker flag `-ObjC`. Still no luck. I have included my super simple test project [here and linked below](http://owolf.net/uploads/StackOverflow/GPUITest.zip) if anyone wants to take a look.

I know this must be documented and basic, but I searched on GitHub but did not find reference to this particular issue.

Thanks for reading.
