I'm not sure exactly how it works but from the modularisation discussion 
it's evident that Boost's library structure supports "sub-libraries" 
(aka submodules) that exist in the same repository but are built separately.

I suspect what you'll probably want to do would be to create a "core" 
submodule that each of the separate backend submodules depend on (each 
of those also depending on a single external library as needed), and 
then finally a "front-end" top level that doesn't directly depend on 
anything but the core, but allows any of the DB-specific backends to be 
used with it.

Boost.Numeric seems to be an existing example of a library divided into 
submodules.

Boost.Math seems to be an example of a library without submodules that 
nevertheless builds multiple output libraries.

I'm not sure which style is "preferred".
