Cmake error in Webengine with Qt5.15.14

[sercxjo]

Cmake of my project fails with error:
Could not find a configuration file for package "Qt5Quick" that is
compatible with requested version "5.15.17"
Because in the lib\cmake\Qt5WebEngine\Qt5WebEngineConfig.cmake it is "5.15.17" in find_package and in other files of WebEngine and PDF packages

It should be because we are using QtWebEngine from Git tag instead of the one bundled in the release tarball.
A global replace may be needed after 'make install'
