This issue was reported in the Qt project bug tracker https://bugreports.qt-project.org/browse/QTBUG-32417 .
The library paths for the QtWebKit libraries are always set to the QtWebKit build directory instead of the installation directory for prefix builds of Qt even if we are not making a developer build. This is due to a scope change of the force_independent flag.
