Error! This tutorial requires a deal.II library that was configured with

options
DEAL_II_WITH_MPI = OFF
DEAL_II_WITH_PETSC = OFF

This is while I use the
'cmake -DDEAL_II_DIR=/path/to/the/source .'
command to address the right configurations. Also when I check the cmake
configurations in installed folder they look OK and with correct configurations.
Could you please advise me on this issue as well?
Behrooz -- the error message says what the problem is. step-18 requires
"DEAL_II_WITH_MPI=ON", but your installation has "DEAL_II_WITH_MPI=OFF", and
similarly for PETSc. In order to run step-18, you need to install deal.II with
a PETSc installation and with MPI installed, but you didn't. The steps
necessary to do that are listed in the doc/readme.html file.
