using “-D PKG_KOKKOS=yes” (which is where my new styles need to be unit tested) adds “-Xcudafe;–diag_suppress=unrecognized_pragma” but also using “-D ENABLE_TESTING=on” switches compiler from nvc++ to g++ so i get “unrecognized command-line option ‘-Xcudafe’” and “unrecognized command-line option ‘–diag_suppress=unrecognized_pragma’” errors

i dont see a ctest executable in build dir yet. how are kokkos pair and dihedral styles unit tested with gpu on ? am i doing something wrong with cmake ??
