Unclear lines in CMakeLists

What is the purpose of adding -G when compiling for CUDA? CMAKE_CXX_FLAGS_DEBUG seems to include -g flag.

Trying to include -G, I get errors like

[  5%] Building CXX object _deps/heffte-build/CMakeFiles/Heffte.dir/src/heffte_c.cpp.o

Also, Kokkos_DEVICES is empty in the current approach of compiling IPPL with cmake.

-G is for generating shared objects. I would just remove this, we do not want to have shared object .
