Added bFTGL to extern and updated the Makefiles. I'm guessing there will

need to be tweaks but it seems to work on my linux box.  I haven't
touched any of the other build systems so those will need to be done.

We probably don't need all of this stuff but I figured better to add a little
too much then to little.
