title: How to link GLX?
body: <p>I'm trying to find the compiler flag for linking GLX on a Linux based system. So far, I have (in qt Creator):</p>
  
  <pre><code>unix:LIBS += -lglx -lX11 -lGLEW -lGLU -lGL -lXext -L/usr/X11R6/lib
  </code></pre>
  
  <p>But, that still gives me <code>glxChooseVisual was not declared in this scope</code>, thus preventing my code from compiling.</p>
