HA!  Yes I was confused, too.  apr_dbd_odbc must be added as a project.
It does not become a -dependency- of any particular target.

We'll always build it; we could leave it out of the _try_dbd default list.
But since we can't imagine many users ever inspecting or changing that
code and recompiling it with local changes, the _try_dbd solution is likely
the simplest.

At some point, it would be nice to add some decision making so that the
others, beyond odbc, can be detected if they just reside somewhere in the
LIB and INCLUDE paths :)
