Description
Version 2.2.0 of Qt VS Addin MSVC 2017 invalidates any Qt library other than Qt5.
To confirm, simply attempt to add a non-Qt5 library. You'll get a message saying "Qt5Core.dll" not found - invalid directory.
Hence, the 2.2.0 build made all of my Qt4 libraries invalid and projects dependent on them without the ability to build.
Attempts to compile any non-Qt5 projects results in moc errors stating library Qt5 was used and is invalid.
The FIX is to uninstall 2.2.0 and install the (beta) version 2.1.2
Be sure to disable the auto-update VS feature for the Qt plugin, else you're back to the problem above.
Apparently 2.2.0 is designed not to work with anything other than Qt5.
It would have been helpful for the update to make mention of that in VS. I would have immediately reverted back to 2.1.2.
