[Paraview] Undefined symbols when building an example reader plugin

[Cory Quammen]

Takuya,

I have a similar problem with a simple VTK filter plugin and a
representation plugin. Unfortunately, I don't have a better solution
than what you propose, but I just wanted to confirm that this is a new
problem, at least on Mac OS X.
