[Boost-build] Referring to use-project ids from outside project directory

Subject: [Boost-build] Referring to use-project ids from outside project directory

We have a bunch of libraries that we've given ids with use-project rules 
in the Jamroot.  We have other projects, not under the same Jamroot, 
that need to also refer to the same target.

In other words, with a layout like (with contents in parentheses):

proj1
   Jamroot   ( use-project /proj-libs/Math : lib/math ; )
   lib
     math
       Jamfile

How do I refer to "/proj-libs/Math" from a proj2 in a different directory?

The best solution I could come up with is to rearrange proj1 to have a 
proj-libs directory and in its Jamfile define Math as an alias to 
../lib/math.

Is there a better way?  Is there some convention for organizing the 
interface of targets that are available to use by other projects.
