I had the same issue with windows while trying to keep separated 32 and 64 bit versions of everything. Basically what I did was make a copy of the Shortcuts to the "Visual Studio 2008 Command Prompt" onto the desktop. Next point the shortcut to a new .bat file that contains the contents of the original file it pointed but adds additional paths for all the installed libraries and executables for the "bitness" that the shortcut represents. So for example, I have all my dev stuff installed in C:\Developer\x64 or C:\Developer\i386. Once the command prompt is up and running I can then launch CMake-GUI.exe from there and the proper paths get picked up. There may be better ways to do all of this but this seems to work for me. Here is my "64 bit" .bat file that gets run when the Command Prompt Shortcut gets run:

@SET VSINSTALLDIR=C:\Program Files (x86)\Microsoft Visual Studio 9.0
