title: How to use OpenNI / NITE in xcode?
body: <p>I have installed OpenNI and NITE on my mac osx. </p>
  
  <p>I want to develop some Kinect apps using XCode(3.2.5 currently I used). 
  But after search on web and stackoverflow, but I couldn't find any good resources on how to import those library into an XCode project. </p>
  
  <p>I saw someone use OSCeleton as protocol messager, 
  but I would prefer more native way to do that(use OpenNI directly).  </p>
  
  <p>Can anyone give me some brief hint about how to do that? 
  Even a link is really helpful (sample compilable xcode proj would be great!). 
  Apologize if this topic exists before.</p>
