[solved] Problems building Qt for WinRT using Visual Studio 2013

[intrepidsoldier]

I downloaded the Qt for Windows Runtime Technology Preview from this location:
http://download.qt-project.org/development_releases/qt/winrt-tp/

When I try to build it using the instructions mentioned here:
http://blog.qt.digia.com/blog/2013/12/12/qt-for-windows-runtime-technology-preview-released/

I eventually run into the following error:

@ win_flex --noline --nounistd --outfile=Tokenizer.cpp ........\3rdparty\angle\src\compiler\preprocessor\Tokenizer.l
'win_flex' is not recognized as an internal or external command, operable program or batch file.
NMAKE : fatal error U1077: 'win_flex' : return code '0x1'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\BIN\nmake.exe"' : return code '0x2'

I tried installing sourceforge.net/projects/winflexbison and adding it to the path but that didn't help.

I also tried the suggestion mentioned here:

But that didn't help either.

How do I fix this?
