It would go in user-config.jam (or site-config.jam).
If the library has a standard installation
location it should be found without any
help from the user. There's nothing we
can do on Windows, but on other platforms
we can use the compiler's default search path.

What I mean is that your code should look like:

using zlib ;

if [ zlib.configured ] { ... }

I don't know whether the existing zlib.jam
supports usage like this, but I'll make sure
that something like this works if you need it.
