building version 5.8.0 fails

Foss 2019a:

ml Qt5/5.12.3-GCCcore-8.2.0
ml Python/3.6.6-foss-2019a
ml CMake/3.13.3-GCCcore-8.2.0

Fails the same way:

-- Could NOT find MPI_C (missing: MPI_C_WORKS) 
-- Could NOT find MPI (missing: MPI_C_FOUND C) 
CMake Error at VTK/CMake/vtkModule.cmake:4111 (message):
  Could not find the MPI external dependency.
Call Stack (most recent call first):
  VTK/CMake/vtkModule.cmake:4634 (vtk_module_find_package)
  VTK/Utilities/MPI/CMakeLists.txt:1 (vtk_module_third_party_external)

This problem must be on ParaView’s CMake files side.
