Qt, either 6.2.0 or newer, or 5.15.0 or newer, with the following modules:
QtCore / qtbase
QtQuick (part of qtbase or qtdeclarative in some distributions)
QtSQL (part of qtbase in some distributions)
QtDBus (part of qtbase in some distributions; note that a connection to DBus at runtime is optional)
QtOpenGL
QtWebEngine (if using Qt 5, 5.15.2 or newer), or
alternatively QtWebKit (5.212) - This is not recommended due to known security issues in QtWebKit, you most likely want to use qutebrowser with the default QtWebEngine backend (based on Chromium) instead.
