[Trilinos-Users] about Tpetra + Kokkos app built against installed trilinos

[KESTENER Pierre]

Hello,

The following is a suggestion for a minor improvement in the installed TrilinosConfig.cmake.

On the trilinos tutorial wiki
https://github.com/trilinos/Trilinos_tutorial/wiki/TrilinosHandsOnTutorial
in the section "Learn how to create and use Kokkos with Tpetra."

the suggested CMakeLists.txt's are mostly OK, but if Trilinos has been built with Tpetra+Kokkos and CUDA enabled, i.e. the variable CUDA_NVCC_FLAGS was passed to the main trilinos configure script, activating some nvcc flags
passed to nvcc_wrapper (cuda architecture, uvm, lambda, ...), the precise flags used to build trilinos are not saved
in the installed TrilinosConfig.cmake

I think it would be useful to have those precise flags saved in a variable named something like
Trilinos_CUDA_NVCC_FLAGS
it would make easier afterwards to build a CUDA app against an installed trilinos.

Best regards,

Pierre Kestener.
