Hi all, I have a similar issue to earlier in this thread, when i drop my plugins into a 4.15 project, visual studio cannot find any of the headers. Adding bEnforceIWYU = false; should help, right? but it doesn’t. Do I need to rewrite every class to upgrade? Ug.
EDIT. Yes, yes i do. 
rebuilding the plugins without the PCH is the way forward.
