[Interest] Roadmap for Qt Widget Styles. WindowsVista? Fusion? Other?

I may have misunderstood.  I thought that I could use the webkit and 
webkitwidgets components which had built with Qt 5.5.1 (actually move 
them into ...) a build of Qt 5.6.2.

But I'm getting the following error when I run the Qt 5.6.2 qmake.exe on 
our application *.pro files:

  * Project ERROR: Unknown module(s) in QT: webkit webkitwidgets

Can those modules be added to "qmake.exe" after the Qt 5.6.2 configure 
and build?  (Like, are such modules enumerated in an associated text file?).

OR do I have to redo the Qt 5.6.2 configure and build with (somehow) 
adding in the webkit and webkitwidgets modules from Qt 5.6.2.  If so, 
how do I get those modules into that configure and build?

(Note that we are still using VS 2010 SP1, on Windows 8.1, so I can't 
use anything from Qt 5.7).
