    Description

      It's currently not possible to build Qt 6.3 modules against Qt 6.2.

      Attempting this results in errors like

      agent:2021/09/14 07:23:42 build.go:391: CMake Error at CMakeLists.txt:13 (find_package):
agent:2021/09/14 07:23:42 build.go:391:   Could not find a configuration file for package "Qt6" that is compatible
agent:2021/09/14 07:23:42 build.go:391:   with requested version "6.3.0".
agent:2021/09/14 07:23:42 build.go:391:   The following configuration files were considered but not accepted:
agent:2021/09/14 07:23:42 build.go:391:     /Users/qt/work/install/lib/cmake/Qt6/Qt6Config.cmake, version: 6.2.0

      This version restriction makes bumping the version numbers of Qt repositories needlessly cumbersome: the repositories have to be updated in topologically sorted order.

      Also, at some point we certainly want to support building a newer QtWebEngine (and potentially other modules) against an older Qt.
