Sure, sounds good to me. Something else to consider - some of the
module names are very long. For example, when I select this one, this
is what I see at the bottom of ccmake:

Module_ITKBinaryMathematicalMorphology: Request building
ITKBinaryMathematicalMorphol

Is there a way to not display the variable name? That would give us
twice as much space to work with. It is implied that the text at the
bottom is related to the currently selected variable, right? Also, the
"Request building [module name]" also seems unnecessary, and takes up
valuable space. Thoughts?
