title: Libraries included in Compile Sources are not found
body: <p>I have included SBJson libraries in my project, with copy option checked, and they are listed in the Build Phase/Compile Sources section. Despite when I type #import "SBJson.h" " autocomplete suggests SBJson.h, when I compile the project it fails with "file not found" error. I have checked Search paths values and all seems to be fine, but the issue still persists.</p>
  
  <p>Many thanks. </p>
