[CMake] Getting cmake to apply patches

[Hugh Sorby]

Thanks Alan,

I will attempt to:

1) search the CMake bug tracker (not very good at this most never seem 
to find anything relevant)
2) add new bug if 1) fails to bear any fruit.

Unfortunately the

cmake -E chdir netgen patch -p0 < netgen-4.9.11.patch

doesn't work so well on Windows Vista which is why I was trying to use 
the -i option.
