It probably can be done via some more explicit jam code. OTOH, I'm really 
wondering if we should open to user a way to get searched library *without*
declaring a target.

The original idea was that you can write "your_cool_lib" and don't care if the 
lib if regularly built, searched or just lying here as a .lib file.

But for many cases, this flexibility is not necessary. I think that even now, 
you can use

exe a : a.cpp : <find-shared-library>a.lib ;

except that the feature is not documented. What do people think?

Such a rule can be easily written I guess. I just not sure it's very needed, 
especially if ... (see below)...

... as this should allow to do manual things. The feature is sheduled for M11, 
so this is not so distant future.
