...and the link is http://www.dependencywalker.com/

As Burlen suggested, dependency walker can be useful for debugging dll
issues.  Try looking at your plugin with dependency walker, and it may
also be helpful to look at paraview.exe.

When you load  a dll on windows *all* of its dependencies must be found, either in the applications run directory (in this case that's the ParaView.exe location) or in the PATH. This all has to do with the way Windows resolves shared library dependencies. Your plugin won't work unless all of the dependencies are in the PATH or the same folder as ParaView.exe. In the 3.6 release we are adding the plugin's bin directory to the search space during/prior plugin load behind the scenes to get around these type of issues.
