Downloading and Building Qt 5.2.1 (Qt Source Package) from Digia / 2-12-2014
(1) Log on to Digia Qt Customer Support Portal ... http://qt.digia.com/Log-in-Customer-Portal/
... my login name is Philip.Weinstein@colorado.edu.
(2) "My Downloads" tab
Download: qt-everywhere-enterprise-src-5.2.1.zip -- Qt Source Package, Full Framework with Windows style line endings.
(Provisional): Download: qt-vs-addin-1.2.2.exe -- Qt Visual Studio Addin for Qt5/
(3) Extract and move the top-level directory to C:\Riverware\tools\Qt-521\
SUSPENDED ... it turns out that I don't need to use Qt5 for my current purposes (QML / Qt Quick Training).
