I am working on updating paraview-feedstock from conda-forge for OpenMPI and MPICH support. I followed patterns from mpi4py and hdf5/h5py to see how to incorporate the correct MPI libraries. Following that, I added -DPARAVIEW\_USE\_MPI=ON option to cmake command.
See [https://github.com/bhermanmit/paraview-feedstock/commit/a278d7fef1ff6a820e4120e7f02e93f23efabb92](https://github.com/bhermanmit/paraview-feedstock/commit/a278d7fef1ff6a820e4120e7f02e93f23efabb92).
Each of my parallel builds failed with an error when building vtkIceTCore. The error is:
```

The entire build can be found at: [https://dev.azure.com/conda-forge/84710dde-1620-425b-80d0-4cf5baca359d/\_apis/build/builds/126672/logs/145](https://dev.azure.com/conda-forge/84710dde-1620-425b-80d0-4cf5baca359d/_apis/build/builds/126672/logs/145)
Any ideas how I can fix this?

It looks like something is doing `#define inline` to something invalid. Could you please provide the preprocessed output for the file in question?
