| Any help on how to get the setup working is really appreciated and thanks in advanced. | |
| ### vvbandeira | |
| Please install a newer version of `nvcc` and try again. As per NVIDIA docs, you will require at least v11; see more [here](https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#c-17-language-features). | |
| ### maliberty | |
| If we bump to cmake 3.10 then https://cmake.org/cmake/help/latest/module/FindCUDA.html suggests we can use the usual VERSION keyword. | |
| FYI - the use of CUDA is quite minimal and probably not worth the bother at this point. | |
