How to install CUDA 9.2 on Linux Mint 19

I would like to install CUDA 9.2. on Linux Mint 19. It was possible to [install CUDA on Linux Mint 18.3](https://unix.stackexchange.com/questions/433743/how-to-install-cuda-9-1-on-mint-18-3/435095) even though Linux Mint is not an [officially supported distribution](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/#system-requirements) . However, Linux Mint 18 was based on Ubuntu 16.04, while the newer Linux Mint 19 is based on Ubuntu 18.04 ([wikipedia](https://en.wikipedia.org/wiki/Linux_Mint_version_history)) . Ubuntu 18.04 seems to have a [super easy solution](https://askubuntu.com/questions/1028830/how-do-i-install-cuda-on-ubuntu-18-04?rq=1) (most popular answer) which is also tempting but I would prefer to avoid switching distros if I can avoid it.
