Ivy buildlist transitivity

[pe...@devinlec.com]

Hi everyone,

Here is my problem :

I have a big project "A" depending on 3 modules "B", "C", "D". Each of 
these 3 modules depend on the same other module "E".

I want to be able to build independently either "B", "C", "D" or "A", so 
in each of the 3 modules' build files I have put a buildlist containing 
"E". And in the build of "A" I have put a buildlist containing "B", "C" 
and "D".

But when I build "A", I can see that "E" is built 3 times, from each of 
its parents... How can I avoid this? I looked at the "leaf" and "root" 
concepts but I don't think this will be useful to me...

Any help appreciated.

Thanks a lot.
