Unsolved Webengine example fail with "Unknown module(s) in QT: webengine"

Hello @Konstantin-Tokarev ,

I tried with 5.8.0 and 5.9.2 and your corresponding release of QtWebKit, seems still the same symptom, the memory will keep increasing if I refresh the page repeatedly.

BTW, the html pages I used are generated via vuejs, is that OK?

Thanks a lot.

Best regards, Jason
