Please allow to use the externally installed kokkos package when available

[yurivict]

Currently parthenon uses the git submodule.

Parthenon installs the bundled kokkos library which would cause conflicts with many other packages.

Welcome @yurivict

this is already possible if you set PARTHENON_IMPORT_KOKKOS=ON, which results in a standard find_package(Kokkos 4) call (instead of using the submodule).

Cheers,

Philipp

PS: Please close the issue if that solves your problem.

PPS: I'd nice if you briefly introduce yourself (see #862) to the community as we're interested in our user base (and their needs/requirements) and how they came across Parthenon.

This works.

Thank you for your advise.
