GitHub/git+Cmake+Clion
This document discusses Git, GitHub, CMake, and CLion. It provides an overview of each tool: - Git is a version control system created by Linus Torvalds for Linux kernel development. It supports non-linear development and distributed development histories. - GitHub provides hosting for Git repositories and additional features like issue tracking. It has become central to the Git ecosystem. - CMake is a build system that generates native makefiles and workspaces for developers. It supports dependency management, testing, and packaging. - CLion is an IDE with features for CMake projects like navigation, refactoring, debugging, and Git integration. It helps manage development workflows.
