Hi Alex, thx for your answer.

Well, It's not what I'am thinking of.

We have a project tree like this:

project A: generate A.exe (link with sub project lib)
  project A1: generate somelib.a (link with sub project objects)
    project A1'  : generate toto.o titi.o
    project A1'' : generate tata.o tutu.o
  project A2: generate someotherlib.a
  etc...

Ok, this is silly, but this is legacy and we can't/don't want to change
that. We are using some crappy IDE now that uses project files that I'am
parsing and create a CMakeFile equivalent. The idea is then to have Eclipse
project files that emulates the exact project tree we have today.

That's why I have projects that produce .o only. So the idea is to separate
the definition of what a project is (a group of source files) and what it
produces (executable, library or nothing). The problem I have with
CMakeFile now is that I don't see how I can define a project without
defining what it produces.

Thanks.
