title: Compiling an OpenCL program using a CL/cl.h file
body: <p>I have sample "Hello, World!" code from the net and I want to run it on the GPU on my university's server. When I type "gcc main.c," it responds with:</p>
  
  <blockquote>
    <p>CL/cl.h: No such file or directory</p>
  </blockquote>
  
  <p>What should I do? How can I have this header file?</p>
