Thanks for the help.  We're using CTK in our ImageSurfer2 program 
that lets biologists do visualization on 3D confocal microscopy data 
sets. (www.imagesurfer.org, next version).

Adding that line to the path didn't help.  It still builds Graph.exe 
and then fails to run it.  That path is included in my environment, 
and is seen both in the CMD path and in the MinGW environment.  When 
I try to run DGraph.exe from the MINGW shell or from the command 
prompt, I get a different error (wrong version of QtCore4.dll; that 
didn't used to happen).

Actually, now that is the error I am also getting from CMake.  I 
don't have the Qt stuff in my path because the build I'm using for 
Paraview and CTK is different from the one I use for other projects 
(which is a standard binary install).

It is in my path, which is what is confusing me.

Another symptom: sometimes during the build process, CMake itself 
(GUI) is unable to find the compiler during configuration and I have 
to quit and restart it to make it work again.

GIT_COMMAND was the only one visible.  Once I set it, GIT_EXECUTABLE 
became visible and needed to be set.
