I have qt-win-free-msvc-3.3.3, which contains everything, including 
qmake.exe.  That's how I was building the ex_alpha_shapes_2.exe.
I actually was able to compile all of the examples and demos in the past by 
using qt-win-free-msvc-3.3.3.

Then my drive crashed (and I hadn't made a drive image prior to that from 
which to restore anything done in the past 8 mos.).

Now, in trying to replicate the setup, I'm on to the demo for 
ex_alpha_shapes_2.  This 'CGAL_Qt3-vc90-mt.lib' issue is infuriating.  I had 
encountered the exact same problem in October 2009, but I somehow solved it 
without noting what I did, either online in the mailing list or off.

If the QT_QMAKE_EXECUTABLE line item is Qt4 specific, that's cool--I'm not 
using Qt4 anyway to try to compile this demo.  I just wanted to cover all of 
the bases in my questions in case that's what was causing my 
CGAL_Qt3-vc90-mt.lib failure.

The Environment Variables seem in order, as does the CMakeCache.
