Dear all,

Please help build ParaView with VTK-m plugins with CUDA support enabled

On [Release Notes](https://www.paraview.org/Wiki/ParaView_Release_Notes#VTK-m_Plugin) for _VTK-m_ plugin it is stated

> If desired, you can enable GPU support via CUDA by building ParaView from source with a VTK-m that has CUDA support enabled.

I’ve built VTK-m with CUDA enabled flag as mentioned in official VTK manual or on [this](https://gitlab.kitware.com/vtk/vtk-m/blob/master/README.md#building) link. And installed it via `make install`. It installed header files into `/usr/local/lib|share` folders

I also picked up ParaView from sources and following official [build](https://github.com/Kitware/ParaView/blob/master/Documentation/dev/build.md) guide for ParaView itself compiled it from source.

But I didn’t see anywhere how to tell _ninja_ builder which compiles ParaView where to pick-up my compiled VTK-m with CUDA support?

By default ParaView repository has VTK-m git submodule and I suspect it still uses it and not recompiled one.

I’m on Ubuntu 18.04.

AFAIK, VTK does not allow to build with an external VTK-m and ParaView does not allow to build with an external VTK.

If I’m not mistaken, building ParaView with CUDA and VTK-m enabled should give what you are looking for.

Thank you for the clarifications. Official docs kind of not clear on this.  
If no other confirmation replies will be given will assume that I did everything correct
