[vtkusers] Can't generate executable file from Cone.cxx example

[Paolo Grossi]

Thanks Cory for your quick answer.
I didn't receive an error during the configuration with ccmake.
I tried to build the example outside the main directory and to correct the
CMakeLists.txt, but the result is always the same.

Regards,
Paolo Grossi.
