Can you build a debug version of cmake and get a call stack, or send a 
complete example that shows the problem.  Also, what version of cmake is 
this, and did you build it yourself?  Does the release from 
www.cmake.org work?

I used the example you gave and it would not crash for me.

You need to set cmake variables and not ENV variables.  Your environment 
must be set outside
of cmake for this to work.   You have to remember once cmake is done 
running it creates
build files that are used by some other program (make or devenv).  It is 
no longer running
and does not have anything to do with the environment.
