CMake for the Impatient
summary
Shows a working minimal CMakeLists.txt that builds main.cpp into world.exe using real commands cmake -B bin then cmake --build bin, and demonstrates generator switching between Visual Studio, GNU make and Ninja (Ninja is notably faster). Shows dependency inference: changing a header triggers incremental rebuild without rerunning configuration. Pulls third‑party code with fetch_content (GoogleTest, Catch2) and finds packages like SFML with find_package, including debug vs release link choices. Continuous integration and cross‑toolchain builds are proven feasible.
