Hi Alan, Phil,
I was just looking at the Tk/X Window problem myself. It would seem that having the X Window Server running and setting the DISPLAY variable to :0.0 (that is the name of the X Window Server that Cygwin runs), wish and Tk are happy and so is Cmake. The tests are now running, so that will take a while. (I thought I had Itk installed, but apparently not - installing that too and restarting the tests ...)
