Chu is still having a problem:
Dear Robert,

I find that when I type make config under the SuiteSparse folder, I got

CUDA library: CUDART_LIB= /usr/local/cuda/lib64/libcudart.so
CUBLAS library: CUBLAS_LIB= /usr/local/cuda/lib64/libcublas.so

but if I type sudo make config, I got

CUDA library: CUDART_LIB= 
CUBLAS library: CUBLAS_LIB= 

It seems that the SuiteSparse can't find the correct PATH of CUDA. I think it can be the reason. 
But when I modify the SuiteSparse_config.mk with

    ifneq ($(CUDA),no)
        CUDA_PATH = $(/usr/local/cuda)
    endif

and run sudo make config, I also got null CUDA&CUBLAS libary.

I'll appreciate if you could give some suggestions.
