Can't Load Plugin in FL {SOLVED}

My problem is extremely similar to the one in this post: Problem loading plugin on FLStudio

i.e. my plugin works standalone and in AudioPluginHost, but not in FL — error on scan, “make sure it’s installed correctly” etc.

The differences are that it doesn’t work even on my dev machine, and that setting my builds to be statically linked doesn’t fix the issue. Additionally, I don’t have any additional third party libraries beyond JUCE.

Any ideas as to what could be happening?

Nevermind, I got it figured out. But for posterity:

I had my plugin configured as “midi output” in Projucer. Unchecking that (along with static linking) made it work.
