Prior to reconfiguration, make sure you remove any leftovers from the previous build.In fact, even if I installed python2, I still failed to build QtWebEngine with the same above ERROR messages.
It looks it's recommended to build QtWebEngine separately, for instance: https://www.linuxfromscratch.org/blfs/view/svn/x/qtwebengine.html

To compile QtWebEngine you have to install some dependencies: https://wiki.qt.io/Building_Qt_5_from_Git
