Converting an old project into the CMake world, I chose not to engage the CMake Tools extension for this project because it keeps more configuration under the hood than I’m comfortable with. I’d rather see everything explicitly, so I wrote my own tasks.json and launch.json. (Which will probably become more important when I get to cross compiling, which is in my list of ambitions for this project.) And it builds, and runs.

Started beginning steps with C++ on VS Code using guide on VS website.
First 3 videos went well but can’t follow steps in 4th video. Only difference is that my CPP file is in a subdirectory as it continues from 3rd video.
