How can I make NVIDIA nvrtc available on my VM?

I have a repository which uses CUDA.

In the past, I only used the CUDA Runtime API, and was able to make it available to me using some copy-and-paste’ing from other projects’ .travis.yml (see below). Now, I also need to use CUDA’s nvrtc library. I know it’s supposed to be part of the CUDA distribution - but somehow it’s missing during the build on the VMs. What do I do?

More generally - is there a way to get a shell session on one of these VMs so as to “poke around” and check what’s available and what’s not using apt, find, and similar tools? If I could do that maybe I could figure things out on my own.
