I used cudarc driver API to automatically detect compute capabilities at build time, which seems more practical than relying on the CUDA_COMPUTE_CAP environment variable:
If you prefer a different approach (e.g., nvidia-smi or env var only), I'm happy to adjust.
Currently, the generator's compute_cap method depends on the merging of Narsil/bindgen_cuda#18. And if Narsil/bindgen_cuda#16 is merged, it would be possible to extend CUBIN generation to multiple architectures to accelerate startup and optimization.
