I have tried set(CMAKE_CXX_STANDARD 17) set(CMAKE_CUDA_STANDARD 14) set(CMAKE_CUDA_STANDARD_REQUIRED TRUE) set(CMAKE_CXX_STANDARD_REQUIRED TRUE) but it does not work！

I saw this error several times now on linux, somehow the CUDA env is not set up well and it does not find its components, like nvcc; try https://stackoverflow.com/a/19981506/1622193 or/and setting export CUDACXX=/usr/local/cuda/bin/nvcc

thank you very much.I add export CUDACXX=/usr/local/cuda/bin/nvcc in the ~/.bashrc and it does work. lol
