not sure why cmake didn't install with install-deps.sh, I didn't notice until I went to build openCV and it couldn't find command cmake.
I installed cmake via the command line and continued with the instructions.
I started with a fresh install and tried to pay more attention to any errors that occurred during install-deps.sh... turns out there weren't any this time. ¯_(ツ)_/¯
