Methods to fix "unresolved external symbol" errors (in ofxMIDI)?

Hello. I’m trying to run ofxMIDI in oF 0.07 using Visual Studio 2010. I’ve got this running in Code::Blocks in oF 0.62, but need to upgrade. I get the following error. In addition, I see very similar errors when trying to install other addons not included in the fat download. Is there a strategy or information source someone can recommend to get past these roadblocks?

Thanks.
