My idea was more like proposing a feature request + patch in order to make
the feature go in upstream CMake.

I cannot ensure it will but...

this may be discussed by people listening to the list :-]

My opinion is that it's sometimes annoying to have several ways to do
something  (-D OPT=ON vs --enable-opt) but it can ease the transition
and/or some common place way to handle option on the command line.

I see.
