Thank you, I figured that out this morning (france), and I was quite 
reluctant to edit my system's variables :
1)how portable would be such a solution?
2)would I face this type of problem if I compile and install ITK without 
shared libs (ITK_SHARED_LIBS = OFF)?
3)howto compile my executable without shared libraries (if I want to put 
it all in the executable) if I installed itk on my system *with* shared 
libraries.

however, the solution is indeed to edit the .profile and export ITK's 
shared libs folder to DYLD_LIBRARY_PATH .

Thanks to your help, I could get it up and running, thank you very much 
for your attention !
Regards,

Antonin

PS : some details which are not in the tutorial :
1)you need to put your project within Eclipse's workspace, otherwise, 
even if you specify absolute paths, eclipse will struggle finding 
sources and binaries.
2)if you use shared libraries, you need to add that to eclipse's 
environment variables
this may be obvious for most users.
I was looking for this issue and found out that one also needs to 
manually edit the DYLD_LIBRARY_PATH for VTK.
