[Paraview] Building a ParaView plugin

[Peter Schmitt]

Hi John,

You might be able to get past the "error while loading shared libraries:
libvtkCommon.so.pv3.8" problem by prepending to your LD_LIBRARY_PATH.  In
bash:

export
LD_LIBRARY_PATH=..../path/containing/libvtkCommon.so.pv3.8:$LD_LIBRARY_PATH


Cheers,
Pete
