[CMake] Forwarding parameters to cmake through cmake-gui

[physhh .]

The question is: What is the expected behavior?

Execute it per configure but don't overwrite variables? What if one really
wants to overwrite?
Execute it once every time the binary directory changes? Changing stuff
only through setting the path is bad.
Other possiblities?
