Summary:                    generator expression $<1:...> and $<0:...> fail with
white space in provided strings.
Description: 
the below example breaks when spaces are in the argument lists.

for the release configuration everything works as expected as the argument list
contains just a single entry. but for the debug configuration $<1:something
something dark side> is inserted into the argument list.

this is very urgend as CMake does offer no other way to set different arguments
to the custom commands depending on the configuration!

set(SCM_ARGS_A something)
set(SCM_ARGS_B something something dark side)

add_custom_command(OUTPUT   ${CUDA_NVCC_OUTPUT_FILE}
                               COMMAND  ${SCM_CUDA_NVCC_COMMAND}
                                   ARGS $<$<CONFIG:Release>:${SCM_ARGS_A}>
                                        $<$<CONFIG:Debug>:${SCM_ARGS_B }>
                                        ${SCM_CUDA_NVCC_OPTIONS} 
                                        ${SCM_CUDA_NVCC_INC_DIR_STRING}
                                        ${SCM_CUDA_NVCC_DEF_STRING}
                                        -o \"${CUDA_NVCC_OUTPUT_FILE}\"
                                        \"${input_file}\"
                               MAIN_DEPENDENCY ${input_file}
                               DEPENDS  ${input_file}
