Great.

Well, I am no CMake expert and looking at other CMakeLists.txt files
and the CMake.pdf isn't too revealing on how this could be done
(easily).  What I'd like to do is to run the following command:

 python -c "import Image"

if the exit status is 0, then run the test, if not don't run it.

I will try and do that.

I agree and doubt that it would be worth it.
