I suspect deleting the cache in cmake-gui then running cmake-gui from
the windows shortcut will break it again.

BTW, I usually run cmake-gui from a visual studio command prompt. The
reason for this is I use more than visual studio compiler and also use
32 and 64 bit in different build trees so I have command prompts with
different environment variables set that help cmake to find the
correct libraries for the build tree that I am currently using.
