title: Glut deprecation in Mac OSX 10.9, IDE: QT Creator
body: <p>I was trying to build an opengl program on qt creator, installed on my mac, with osx 10.9. 
  I got several warnings on glut functions about its deprecation in osx10.9, a sample error message is like:</p>
  
  <p>'glutInit' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations]
      glutInit(&amp;argc, &amp;argv);
      ^</p>
  
  <p>I wonder if GLUT.h is not usable anymore in osx10.9? According to some other posts, it is said that as long as we change "OS X Deployment Target" back to OSX10.8, then it works. How to do so in qtcreator? Thank you!</p>
