[Ves] VES on the Desktop

[kranial smok]

Thanks Pat. That made all the difference.

I was confused whether the OpenGL or OpenGLES libraries were being used
because I remember having to install the mesa OpenGLES development package
to successfully build VES. I'm building on Ubuntu 12.04 x86_64.

Thanks again.
