I wish somebody would write a book. Even an online book. An all-encompassing book just about how to link/build C++ projects and all the different solutions people use and how they work in practice. Common ways to organize and configure C++ project builds. How Linux distros each differ in where libraries are stored and how to find and link them. Common issues and how to fix them. But it also needs to convey how all these things work and help you create a mental model that allows you to also find your own solutions.
