Idea: do not rely on nvcc_wrapper for the cuda-vs-host compiler magic, but use native

E.g., do something like this: <div class="snippet-clipboard-content notranslate po

E.g., do something like this:

...
if (Kokkos_ENABLE_CUDA)
  set(Kokkos_LANG CUDA)
else ()
  set (Kokkos_LANG CXX)
endif()
project (ekat C Fortran ${Kokkos_LANG})
...

add_library(ekat ${EKAT_SOURCES})
set_source_files_properties (${EKAT_SOURCES} PROPERTIES LANGUAGE ${Kokkos_LANG})

This should a) be made flexible so to only set the language for cxx sources (do a foreach over src files, check file language, if cxx, then override with ${Kokkos_LANG}), and b) provide macros for downstream apps to create libs/execs, and do this language setting magic inside these macros. Something like

macro(ekat_add_library libName ...)
  add_library(${libName} ...)
  # set LANGUAGE=${Kokkos_LANG} for all CXX sources
endmacro()

from ekat.
