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

Pei@jiapei1000 1) QtWebEngine requires python2 because chromium requires it so you can't change it. 2) I have tried to compile QtWebEngine with ubuntu 20.04 but using ubuntu 18.04 with the same configuration I have been able to compile.
To compile QtWebEngine you have to install some dependencies: https://wiki.qt.io/Building_Qt_5_from_Git
