title: Adding Cocos2d (2.0) to existing iPhone Project
body: <p>(Posting for <strong>reference purpose only</strong>. So I will answer right away)</p>
  
  <p>I used Cocos2d 2.0 on Xcode 4.6.3. </p>
  
  <p>I faced a 'Lexical or Preprocessor issue' about <strong>kazmath/SomeFile.h</strong> file not found. </p>
  
  <p>Looked around but could find only outdated questions.
  I added Cocos2d to iPhone project and will discuss the steps i have taken so that it can help people looking for doing this and facing issues...</p>
