Hello,

I need to add a dependency to a library dependency.  I have a GUI
library that can support multiple underlying window managers, and in
some cases, it is the task of the user of the GUI library to specify
how to link/include the window manager files.

For example, I might have a scenario like this:

B: a window manager library
G: a GUI library (can work with B, but knows nothing about the
location of "B" include files on the system)
Gplus: a library that is based on G
E: an executable that wants to use Gplus with the B window manager

The goal is to allow E to specify that G/Gplus should use B:

exe E : ... : <library>Gplus<use_window_manager>B ;

The desired effect is that B would get added to the requirements /
usage-requirements of G.

I've tried a bunch of things to get this or similar to work but keep
getting nowhere.  Can someone tell me how to do this?

I can provide more information if it's not clear what I'm trying to
do, or if you're interested in what I tried unsuccessfully.

Thanks,

Stjepan
