For my plugin I need hdf5cpp. In hdf5.cmake are the lines

```auto
...
DEPENDS_OPTIONAL hdf5cpp
...
-DHDF5_BUILD_CPP_LIB:BOOL=${hdf5cpp_enabled}

```

How can I enable hdf5cpp?

Thanks

Hi!  
You can add `hdf5cpp` as a dependency to your plugin. This will cause hdf5 to be built with the CPP wrapper, and added as a dependency to your plugin.

If you look at `hdf5cpp.cmake` you will see it is a dummy target which sets the `hdf5cpp_enabled` variable and depends on `hdf5`.

HTH,

Thanks for the reply. Up to know (at least 5.4) I built the plugin externally, I’ll try to integrate it into PV.

I cannot get it to work. It seems, there is no ENABLE\_paraviewpluginsexternal any more?!  
I could not yet find a way to include building the plugin together with paraview.

When I try to build the plugin manually by providing ParaView\_DIR, there is the error

```auto
superbuild/paraview/build/lib/cmake/paraview-5.10/ParaViewPlugin.cmake:1064 (message):
  Failed to find the required module hdf5_cpp-static.

```

How can I tell paraview to build my plugin?  
Any help is very much appreciated!

I solved this issue by manually changing the cmake configuration of cmake. I could manually build the plugin and load it to my built paraview.
