What's the native handle for CUDA memory? Could you use a static_cast instead? Also you can use auto instead of float* since you already specify the exact type with the cast.

CUdeviceptr is the native type but is not used in CUDA Runtime API, just using the pointer is enough. Cannot static cast because it converts a number into a pointer

Why is CMake 3.17 such a strong requirement?

The
find_package(CUDAToolkit)used below simplifies the setting up of the project, but is only available on latest cmake.
