You need *Qt3* (not Qt4), to compile the CGAL_Qt3 library. Unless you have 
paid to buy Qt3 from Nokia/Trolltech, I doubt you have Qt3 on your system. 
The 
qmake.exe you specify is probably a qmake.exe from Qt4. Am I wrong?

If you want to see the alpha_shape_2 demo, download the precompiled version 
from here:
http://www.cgal.org/Manual/last/doc_html/cgal_manual/packages.html#part_IX

You will need the DLLs of that file too:
