Reproduce the GPU build from the `build` directory with `make`, then inspect `src/kern/gpu/kernel_gpu.cu` and the reported compiler failure involving `/usr/lib/gcc/x86_64-linux-gnu/11/include/serializeintrin.h`. Also review `src/kern/naive/quantize.h` for the warning. Done means the GPU target configures and compiles without the reported NVCC error.
