[CMake] Forwarding parameters to cmake through cmake-gui

[physhh .]

I've tried to implement it in the same way as CCMake seem to do it.
Because I can't compare it =>
Could somone with access to ccmake test this:
- Start CCMake with -D foo=123
- Configure
- Question: Is foo displayed in the variable list?
- Add/Edit foo to some other value
- Configure
- Question: Was foo overwritten with "123"?

Thanks
