Hello,
I am trying to build and load the ElevationFilter from the Examples directory. Build completes successfully but loading the plugin from the GUI returns the following error:
```
ERROR: In /home/buildslave/dashboards/buildbot/paraview-pvbinsdash-linux-shared-release_superbuild/build/superbuild/paraview/src/Remoting/Core/vtkPVPluginLoader.cxx, line 519
vtkPVPluginLoader (0x62fb1e0): libElevationFilters.so: cannot open shared object file: No such file or directory
```
Steps followed:
1. Use [paraview-plugin-builder](https://gitlab.kitware.com/paraview/paraview-plugin-builder) to build a docker image for paraview 5.8.0
2. copy `Examples/Plugins/ElevationFilter` directory from master branch
3. run `./run_build_plugin.sh -d ElevationFilter v5.8.0`
4. the above command completes and generates `ElevationFilter.so libElevationFilters.so`
5. Open Paraview 5.8.0 (downloaded from [https://www.paraview.org/download/](https://www.paraview.org/download/) )
6. Attempt to load the plugin (`ElevationFilter.so`) through the GUI.
Note:
`ldd ElevationFilter.so` returns:
```auto
$ ldd ElevationFilter.so
...
libElevationFilters.so (0x00007f6e818de000)
...
```
System:
Ubuntu 16.04.06, 4.4.0-176-generic
Thank you.

this example produce two .so files that you have to recover and place together in a folder.
`ElevationFilter.so libElevationFilters.so`
It may be nice to improve paraview-plugin-builder to make that clearer.
You can modify this example quite easily to makes it link statically with the second lib so this is not needed.

Thank you for the quick reply.
When I tried to load `ElevationFilter.so` both of the `.so` files were in the same directory. I tried also to put them in `./bin/plugins` and `./lib/plugins/` but had no luck.
It looks however that adding
```auto
set(CMAKE_INSTALL_RPATH $ORIGIN)
set(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE)
```
in the top level `CMakeLists.txt` solves the issue (at least on my platform).

Looks a platform specific issue then. Thanks for sharing.
Tbh I tend to build my internal module lib statically to avoid needing to move around multiple files.
Done with :
```
vtk_module_add_module(module
FORCE_STATIC
...
```
