[Paraview] Debugging ParaView while trying to add a reader

[Kent Eschenberg]

Tom,

I've attached 2 xml files that I use to add a reader (edited slightly). 
Maybe you'll see something that suggests a fix to your problem.

CMake seems to ignore the debug option when entered as "Debug" even though 
that is how it is shown in that item's help.  Using "DEBUG" seems to work
