APIBind provides a formal dependencies implementation system at the 
C++ namespace level.

git submodules are an effective, if brutal, dependency fetching 
implementation. They work.

APIBind provides a formal API versioning implementation. So library A 
can depend on library X v1 and library B can depend on library X v2 
and both can coexist in the same translation unit.

APIBind also allows dependency injection so users of libraries can 
inject the implementations they choose. API and ABI separation and 
coexistence also works as expected, including in the same translation 
unit.
