I think that the FindCUDA-arm-5.5 topic just merged to stage could also make
use of CMAKE_<LANG>_COMPILER_TARGET. I don't know anything about CUDA or
about NVCC, but --target-cpu-architecture looks to me like it solves the
same problem as the clang and qcc case.
I didn't find any pre-existing *TARGET_CPU* or *CPU_ARCH* in the CMake code.
Thanks,
Steve.
