Given that you have a clean installation of CentOS 7 which was already updated,
by you, then you still have some dependencies to install make and install the
external Zsh from the source. You must be root to get the stuff done.
For a Oh-My-Zsh Shell custommized theme, called Spaceship Prompt
it's reecommended to install the Powerline Fonts. In a CentOS 7 machine it can be a little more work, than doing it
via a package manager.
This is a slightly modified update to Daniel Kornev's excellent post which goes into more detail about why building from source is necessary on 18.04. His post was missing a few dependencies that I didn't have installed namely cmake, opencv and pkg-config. The following steps should get you a working build of openalpr on a fresh install of Ubuntu 18.04.
If you're not working with a fresh install, this might be a good time to clean and update your system before proceeding. (Optional)
$ sudo apt update #fetch list of available updates
$ sudo apt upgrade #install updates – does not remove packages
