Can't build VST3 or AAX on Windows

…a lot has happened since then, see e.g.

So check, if these changes help you, otherwise I reccomend to start a new thread where you state your problem with more additional data, like do you have the AAX and compiled it? where exactly start the problems, do you have the outdated post build script to copy the target (which works now differently), do you use the git latest tip /master or develop and so on…
