CUDADIR and CUDA on Ubuntu 18.04

Not sure if anyone else is having issues as well, but in Ubuntu 18.04 currently there is no NVIDIA build, however you can install a 'native' package. The difference being that native packages can no longer package all the pieces of CUDA in one directory e.g. /usr/local/cuda-9.0.
So my old OpenMM configuration of just specifying a CUDADIR is not working. Does anyone have a workaround or have any more insight into how OpenMM can recognize my CUDA installation?

How did you install CUDA?

The package you're installing does not come from NVIDIA, and it isn't a supported method of installing CUDA. See
https://devtalk.nvidia.com/default/topi ... a-toolkit/. Instead you need to download it from NVIDIA and install it by following the instructions they provide:

Right which is why I'm asking on the forum to see if anyone had any ideas on making it work. There is no NVIDIA package for Ubuntu 18.04 yet, and I read elsewhere that there are conflicts and thus can't be made to work.
