Weird, it used to work (I even installed it and used the plugin!) but
now I get this too. I would debug it but I have no idea what the error
means or what to look for, the project seems to get built ok (I can see
the generated LV2/VST plugins in the build directory).

Reattaching it as a patch, hopefully someone with more experience can
take it from here.
