Duplication of version info is a pain, the is awkward to avoid if you
want the version info embedded in the Version file for #ifdef purposes
in user code.  One possibility might be to write a script that seeds
the version values in the header from the CMake file, I haven't
investigated this yet - it'd take more time that it does to simply
open to two files in an editor... and adjust a single number in each
one.
