Trilinos: Kokkos: Configure fails on C++11 standard for Nvidia/CUDA using nvcc_wrapper

I am trying to build Trilinos for GPUs using the nvcc_wrapper, but get a configure error

-- Using -std=c++11 for C++11 standard as feature

This used to work two or so weeks ago. Clark Dohrmann is also seeing this error.

@rrdrake how are you setting your environment or configure to use nvcc_wrapper (I couldn't find anything in the posted logs)? If it is not using the same version as the copy in Trilinos/packages/kokkos/bin/nvcc_wrapper then the nvcc_wrapper will need to be updated to be compatible with changes in the kokkos 2.9.99 release.

Edit: Fixed typo in Trilinos' path to nvcc_wrapper

[rrdrake]

Good question, we are using OpenMPI and set OMPI_CXX to the nvcc_wrapper path. So mpicxx ends up using the wrapper.

We are using a copy of nvcc_wrapper - I will try pulling a new one from Trilinos/packages/kokkos/bin.

Using the new nvcc_wrapper solved the configure problems. Thank you.
