thanks a lot mark, your solution is cleaner than what I had in mind so
that's what I tried. your code ran out of the box or so.

I still have a problem though, that is the working directory seems to
be taken into account by cmake. If I follow the Makefile dependancies
I get to:
====== subMakefile generated by cmake ====
                @$(CMAKE_COMMAND) -E cmake_echo_color
--switch=$(COLOR) --blue --bold "executing gengetopt"cd
/home/teto/dir1/dir2 && echo "pwd ${PWD}" &&  /usr/bin/gengetopt -i\
menudescriptor.ggo\

Now if I I launch "make gengetopt", I get this result:
===== result of "make gengetopt" ====
[100%] executing gengetopt
pwd /home/teto/dir1
Error opening input file:  menudescriptor.ggo

My menudescriptor.ggo is in "/home/teto/dir1/dir2". How can I solve
that (well I could eventually give the fullpath to menudescriptor.ggo)
? It feels like the WORKING_DIRECTORY is supplanted by make.

NB: As a sidenote is it possible to declare constants in cmake ?
