Oh, nasty. I keep forgetting that static linking is the default here.

This seems like a real usability problem to me. My project used to
work just fine before auto_link capabilities were added. I specified
that I wanted to link to the dlls by putting them in my sources, and
everything worked. Now I have to add one or more <define>s to all my
targets, or I get confusing errors. Doesn't seem like an
improvement, at least for my usage model.
