How to successfully compile Plugin

I copied the BlankPlugin example and added it to the proper directory so that the engine can compile my Plugin and “use it”. Currently it does nothing, it’s just a copy and paste but for some reason, I keep seeing this:

I’m not sure why? This only happens when I add my plugin to my project, and at the engine level. Same error. Note, the plugin isn’t trying to do anything. It’s blank.

Alright found out that this just doesn’t work on 4.3, or 4.2. I downgraded to 4.1 and works flawlessly I can install and use custom plugins on that version.
