remove netcdfcpp
The netcdf community has moved away from netcdfcpp, which VTK picked years ago, in favor of netcdf_cxx. Not being able to rely on a system netcdfcpp makes packaging and deployment of VTK and ParaView harder than it could be.
VTK and ParaView should drop netcdfcpp and either update to netcdf_cxx or (preferentially) use only the C interface. MPAS, netcdfCAM, UnstructuredPOPReader, and the CDI plugin will need to be updated accordingly.
