Yes... that's what it does. To link with a library you'd need to use
<library-file>feature. Here's an example:

exe a : a.cpp : <library-file>b.a ;

The problem, is that you have to specify *exact* name to the library. That
is, you can't use different variants (debug/release) of it.

I'm afraid that never worked. In fact, smooth project interaction is one of
my personal motivations for V2 and the good news is that using targets across
different projects already works there :-)
