Hey all,

I’m trying to build a ParaView with the _LagrangianParticleTracker_ filter but I am unsure on the build parameters. Currently I am building following the [repository guide](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md) with this code below:

```auto
cmake -GNinja -DPython3_EXECUTABLE=/usr/bin/python3.6 -DPARAVIEW_USE_PYTHON=ON -DPARAVIEW_BUILD_TESTING=ON -DPARAVIEW_USE_MPI=ON -DVTK_SMP_IMPLEMENTATION_TYPE=TBB -DCMAKE_BUILD_TYPE=Release ../paraviewD
ninja

```

I have (I believe) sucessfully built 5.9.0 and 5.8.0 with additional filters compared to the pre-complied downloads available from [ParaView downloads](https://www.paraview.org/download/). I used the `-DPARAVIEW_BUILD_TESTING=ON` parameter based on a [LagrangianParticleTracker Example in this forum](https://discourse.paraview.org/t/lagrangianparticletracker-example-file/571/2).

I presume I require additional [build parameters](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md#build-options) but I unsure what. Does anyone have any ideas or suggestions?

Operating System: ElementaryOS/Linux (Similar structure to Ubuntu)

Well, you need to make sure the plugin is activated in cmake, `PARAVIEW_PLUGIN_ENABLE_LagrangianParticleTracker`

It should be enabled by default though.

Hey Mathieu,

Thank you very much for answering and your reply helped solve my issue.

I made two mistakes; firstly not reading the documentation carefully and secondly not understanding the Lagrangian Particle Tracker is a plugin which presents as a filter.

Firstly, knowing filters are plugins, it would have directed me to the docs for the cmake build parameter code you supplied - [docs for reference](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md#plugin-settings).

Secondly, adding to my initial mistake not understanding plugins presenting as filters, I had to enter the `Tools > Manage Plugins...` to specifically enable the `LagrangianParticleTracker` which was present in my cmake version and the pre-complied ParaView versions available from [ParaView downloads](https://www.paraview.org/download/).

Apologies for my lack of understanding, my problem is now resolved. Thank you!
