# Get required prerequisites from the manual and remove ones that will be replaced by
# custom versions in Docker images. In particular:
#
# - libx11-dev is not needed
# - petsc-dev uses OpenMPI (it is easier to use MPICH for development)
# - petsc-dev uses OpenMPI-based parallel HDF5 (we build our own HDF5)
# - libnetcdf-dev is replaced by a parallel version built from sources
