When lib 'a' <use> lib 'b', it does not cause library 'a' to link with library 'b', it only makes 'b' a dependency for 'a' and integrates 'b' library's usage requirements into build properties of 'a'. Listing a library in another's sources, or using the <library> feature, is another matter though. So if we have
lib b : b.cpp ;
lib a : a.cpp b ; # or, lib a : a.cpp : <library>b ;
exe e : a ; # no need to list 'b' in sources of 'e'
It should just work so that 'e' will be properly linked to 'b'.
This has been my experience at least, please come back if yours happens to be different :-)
