Look at the mpi-default-dev package. Most packages using MPI should 
depend on it (only depending on eg libopenmpi-dev if its specifically 
openmpi dependent).

Edit /usr/share/mpi-default-dev/debian_defaults locally, change openmpi 
-> mpich. Then

# apt install libmpich-dev mpich

# apt remove libopenmpi-dev openmpi-bin
