I think he's suggesting to just add the .cpp files as sources from 
this library that you need to your BBv2 exe target just as you do 
your main.cpp file.  e.g.

<BBv2>
exe my_exec : main.cpp ../library/a.cpp ../library/b.cpp ;

This is a very simple way to do it.  If you need everything in that 
library then you might just use [ glob ], otherwise create a 
variable to hold these files.  Better yet, just make a jamfile for 
building a library binary.  I suggest you look at the following:

ms
