RPATH and LD_LIBRARY_PATH when using ParaView; conflicts with libraries from other application

From my limited understanding of RPATH, I thought that RPATH takes precedence over LD_LIBRARY_PATH, but that does not seem to be happening here.

DT_RPATH does, but DT_RUNPATH does not (and is why DT_RPATH was deprecated). You can see what is being used with readelf -d $library and looking for the DT_ key in use for the paths.

But if there is a simpler way to convince the loader to first use RPATH that would be great.

Nope. LD_LIBRARY_PATH is a blunt tool and affects an entire process tree. I would recommend setting the RPATH in the simulation code to stick to the ParaView it was built against (at least by default).
