Setting up a project

Although CMake can work with almost any file structure for a project, there are some good practices regarding how to organize files. The examples in this book use the following common pattern:

├── CMakeLists.txt
├── build
├── include/project_name
└── src

There are three folders and one file present in a minimal project structure. They are as follows:

• build: The folder where the build files and binaries are placed.
• include/project_name: This folder contains all the header files that are publicly accessible from outside the project. Adding a subfolder that contains the project's name is helpful since includes are done with <project_name/somefile.h>, making it easier to figure out which library a header file is coming from.
• src: This folder contains all the source and header files that are private.
• CMakeLists.txt: This is the root CMake file.
