[CMake] Forwarding parameters to cmake through cmake-gui

[physhh .]

Hey Matthew,

that's interesting. I'm currently at a windows only machine so i can't
check out ccmake but can only lookup the source. It appears that ALL
parameters get "forwarded" to cmake - at least that's what

cmCursesMainForm.cxx:52
> this->CMakeInstance->SetArgs(this->Args);

looks to me.
Why do you think that a simple forward is not enough? ccmake seems to do it
exactly that way?
