the current tree is simply based on common prefixes of the variables.
This could be extended to more levels, if somebody puts work into it.

Currently there is no way to do this.

You can use set_property(CACHE ... STRINGS "option1;option2;...optinonN")
to provide a combobox with a fixed set of options in cmake-gui.

This depends on the IDE and what kind of files need to be generated.
Once added, it has to be maintained, which is usually quite some work.
