You are right. That can be found out having a look at the CMakeLists.txt of 
each demo.

In CGAL-3.4, the demo that use Qt4 are:
  demo/Alpha_shapes_3
  demo/Circular_kernel_2
  demo/GraphicsView
  demo/Polygon
  demo/Polyhedron
  demo/Surface_mesher
  demo/Triangulation_2

What is the output of CMake? Probably you miss the QGLViewer library. There 
should be a message in the CMake output that says the Alpha_shape_3 demo has 
not been configured.

No. We have decided that the Qt4 documentation contains better tutorials and 
reference pages that what we could ship in the CGAL manual.

There exists only some pages about the CGAL classes that have been created to 
interact with the Graphics View Framework of Qt4:
