title: Cant install GPUImage framework - GPUImage.h not found
body: <p>i have an app and i want to install GPUImage framework. I did following steps:</p>
  
  <p>1) Adding project to my app. I did following > XCode->Add Files-> then choose GPUImage.xcodeproj, and select "copy items to destination project"</p>
  
  <p>2) Now it says : <code>Next, go to your application's target and add GPUImage as a Target Dependency</code>. Im not really sure how to achieve that, what i did is - in product->Scheme->Edit scheme i add GPUImage.</p>
  
  <p>3) I add libGPUImage.a to Build Phases -> Link binary with Libraries</p>
  
  <p>4) I tried every solution i had found to finally add full path of GPUImage.xcodeproj to header search path. Nothing work at all. There is a warning - GPUImage.h not found. I had tried many ways to add full path here, everything i did found concerning this error, but still, there is an error.</p>
  
  <p>How could i fix that? Maybe i made mistakes in previous steps? I really wonder how i manage to spend many hours just trying to add framework to my app, and still unsuccessfully..</p>
