Hi,
Trilinos can be build with an external Kokkos package if the version
matches.
The current required version for Kokkos to be compatible with Trilinos
in Debian would be 4.1.0
(https://salsa.debian.org/science-team/trilinos/-/blob/master/packages/tpetra/CMakeLists.txt?ref_type=heads#L27).
In the latest Trilinos version Kokkos would requires the latest release
4.6.0.
Searching a bit in the Trilinos documentation I found -D
TPL_ENABLE_KOKKOS=ON as a CMake configuration flag to build with an
external Kokkos package.
I am not yet sure how to point Trilinos to the external Kokkos install.
Usually Kokkos_ROOT or Kokkos_DIR should be set in the cmake configuration.
If Kokkos can be found in the default paths maybe cmake is capable to
find the install without specifying the path.
This might solve the issue.
Best regards,
Nils
