Comment (by mliradelc):

 I was studying this and I found that '''CC 3.5 is enough'''.

 > == Why happens: ==
 >
 >
 > This error happens because since the latest CUDA SDK (11.0) accepts
 compute capability '''3.5''' - 8.6
 >
 >
 > == How to fix (Workaround): ==
 >
 > The fix is to modify the compute version from 30 to '''35''' in the
 `configure` file:
 > {{{
 > if enabled cuda_nvcc; then
 >     nvcc_default="nvcc"
 >     nvccflags_default="-gencode arch=compute_35,code=sm_35 -O2"
 > else
 >     nvcc_default="clang"
 >     nvccflags_default="--cuda-gpu-arch=sm_35 -O2"
 >     NVCC_C=""
 > fi
 >
 > }}}
