Need mechanism to pass defines to library cpp files

the simplest solution I can think of is to provide two libraries but that is a burden for the developer.

Another way is to use a templates. A very short intro see

Thanks for the references! My c++ experience predates the inclusion of templates in the language, and I have never had a need for that feature before. I will look at the references provided and see about incorporating that solution into the library.
