Hi Alex,
I previously ran into a lot of issues when I tried to install dealii on our
institute's cluster. The OS was different though and I had problems with
PETSc.
I don't know if this helps but this is the relevant section in
dealii-9.2.0/cmake/modules/FindTRILINOS.cmake file which searches for
epetra.
# Look for Epetra_config.h - we'll query it to determine MPI and 64bit
# indices support:
#
DEAL_II_FIND_FILE(EPETRA_CONFIG_H Epetra_config.h
HINTS ${Trilinos_INCLUDE_DIRS}
NO_DEFAULT_PATH NO_CMAKE_ENVIRONMENT_PATH NO_CMAKE_PATH
NO_SYSTEM_ENVIRONMENT_PATH NO_CMAKE_SYSTEM_PATH NO_CMAKE_FIND_ROOT_PATH
)
Notice the hint: it is Trilinos_INCLUDE_DIRS and not TRILINOS_INCLUDE_DIRS.
If your dealii version also has Trilinos in smallcase, then maybe making
this change will do the job. You may even try manually adding the full path
in the cmake module file as a hint.
Hope this helps
