When I start to use a programming language I always have the following questions:
- How do I build/run my program?
- How do I run tests?
- How do I install dependencies?
- How do I integrate all of this in my text editor?
Some languages such as Go come with simple answers to these questions:
go build ./...,
go test ./...,
go get <my module>, install the official Go extension for your editor. Done. But of course in the case of C++, things are ... different 🙃.
The C++ world is way more fragmented, there is a lot of choices of build and meta build tools, various test frameworks (each with its own test runner), lot of way to manage dependencies, etc. Because so much choices can be daunting for people who just want to start with the language, and because I know I will forget how things work, in this article I will document what I've done to get to a fully working environment that answers all my questions in a simple and coherent way. At the end of this guide we will be able to build and run tests in just one click (or command line if that's your thing).
Tools popularity can vary quite a lot from years to years, for example solutions to manage dependencies are still competing against each other and new ones are popping all the time, so I want to be clear that this document is my setup in 2020, hopefully it will stay evergreen in the future, but I wouldn't bet too much on it.
