title: Silencing OpenGL warnings on macOS Mojave
body: <p>My code is full of warnings like </p>
  
  <blockquote>
    <p>'glTranslatef' is deprecated: first deprecated in macOS 10.14 - OpenGL
    API deprecated. (Define GL_SILENCE_DEPRECATION to silence these
    warnings)</p>
  </blockquote>
  
  <p>I did <code>#define GL_SILENCE_DEPRECATION</code> but that didn't fix the issue. 
  I use <code>freeglut</code> that was installed by using <code>brew install freeglut</code></p>
  
  <p>Can I silence it somehow?</p>
