title: Linking error LNK2001: unresolved symbol glePolyCylinder
body: <p>I'm trying to use the <a href="http://www.linas.org/gle/" rel="nofollow">GLE tubing and extrusion library</a> for a personal OpenGL project but I'm stuck with the following error:</p>
  
  <pre><code>error LNK2001: unresolved external symbol "void __cdecl glePolyCylinder(int,double (* const)[3],float (* const)[3],double)" (?glePolyCylinder@@YAXHQAY02NQAY02MN@Z) 
  </code></pre>
  
  <p>I'm using VS Express 2013 to compile. I've created an empty project and compiled the GLE source code into a .lib file, then added this .lib file to the linker dependencies in my main project (Properties -> Linker -> Input -> Additional dependencies) along with the other .lib files I'm using, and I've included the header file with:</p>
  
  <pre><code>#include "gle-3.0.0\src\gle.h"
  </code></pre>
  
  <p>but I still keep getting the error. What am I doing wrong?</p>
