#     SPRAL_PROG_NVCC([compiler-search-list])
#
# DESCRIPTION
#
#  This macro looks for the CUDA C compiler to use. On success, the following
#  variables are defined:
#     $NVCC          The CUDA compiler command
#     $NVCCFLAGS     The flags pased to the CUDA compiler
#     $NVCC_ARCH_SM  The CUDA architectures to compile for
#
