As with all of the recipes in this chapter, ensure that all of the technical requirements have been met, including installing Ubuntu 18.04 or higher and running the following in a Terminal window:
> sudo apt-get install build-essential git cmake
This will ensure your operating system has the proper tools to compile and execute the examples in this recipe. Once you have done this, open a new Terminal. We will use this Terminal to download, compile, and run our examples.
