* Add Boost::locale explicetly to the CMake since nanoodbc requires it
* Don't let nanoodbc add all Boost libraries to the link line, since it
is used in common, and it was pulling the unit test framework into
common then.
nanodbc was overriding the C++ standard library being used, which would
break builds with clang. Additionally, adding Werror unconditionally in
production code is a bad idea because different compiler versions can
change/add warnings and then break the code.
Allows placing parts from an external database that reference symbols from another loaded library.
Includes:
- nanodbc wrapper
- database schematic library plugin
- basic tests
