[vtkusers] not all examples are being built on unix-out-of-source

[Peter J. Bismuti]

I'm trying to go through the VTK examples, but not all of them are built.  I'm 
building on Unix (out-of-source).  

Some of the executables for the examples have been built and are in:

~/VTK/vtk-5.0-linux/bin

Such as the Tutorial examples Cone6, .etc.  I'm trying to look at the GUI/Qt 
examples, for example, and they don't seem to be built anywhere.  Is this 
normal, or has something gone wrong with the build?  

Thanks in advance
