title: "GPUImage.h" not found
body: <p>I am trying to set up <code>GPUImage</code> 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 <code>-ObjC</code>. Still no luck. I have included my super simple test project <a href="http://owolf.net/uploads/StackOverflow/GPUITest.zip" rel="noreferrer">here and linked below</a> if anyone wants to take a look.</p>
  
  <p>I know this must be documented and basic, but I searched on GitHub but did not find reference to this particular issue.</p>
  
  <p>Thanks for reading. </p>
