Yes, I agree, you mean what pedro said, linking directly with the library...

lib project2
: $(cppFiles:BS)
: <source>/project1//project1
;

But when doing that how to specify the project1 to also stage its 
headers and the generated lib in another location ?

That is why I link with the library alias that build the lib, copy 
headers, and the generated lib in another location....

alias library : project1 export_lib export_headers ;

If you know something to do what I want, I will be happy :)

Thx again
