ccmake accepts e.g. -D options to set CMake cache variables. It... does 
appear that cmake-gui does not. That seems like a bug (or at least a 
missing feature that one would naturally expect to exist).

I'm not sure a "forward" option makes sense... what would it mean to 
"forward" e.g. -P or -E?

Rather, I think cmake-gui should just accept directly those options that 
make sense, e.g. -D, -U, -C, -G, -T and probably -W[no-]dev, the same 
way that ccmake does. (Besides, these should affect cmake-gui even 
before cmake is invoked, so merely forwarding them is actually 
insufficient.)
