title: compiling OpenGL program GL/glew.h missing
body: <p>I installed OpenGL onto my computer running Linux Mint following the instructions on <a href="http://anytimeir.wordpress.com/2012/05/16/installing-opengl-development-environment-in-ubuntu/">this tutorial</a>. I am trying to compile a program that uses OpenGL, but I'm getting a compile error: <code>fatal error: GL/glew.h: No such file or directory</code>. I check the /usr/include/GL folder, and glew.h is indeed missing. I don't know why it's missing, because I did the command <code>sudo apt-get install libglew1.5</code> and it gives the output:</p>

  <p>Why is the glew.h file missing?</p>
