As it happens, recent CUDA releases ship with `bin/__nvcc_device_query` which prints out the list of SM capabilities of the GPUs it sees. Even that may not be the right value. E.g. only some of the GPUs on the machine may be intended for compute. It's not that uncommon to have a puny card to drive the display and one or more compute cards we actually want to compile for. There's no point compiling for a GPU variant which will never do any compute.
