A CLOSER LOOK

What is CMake?

CMake is a cross-platform build-system generator that describes targets and dependencies, produces native build files, and integrates testing and packaging tools, helping C and C++ projects support different compilers and environments.

How to use it well

CMake is a useful option for C and C++ projects supporting multiple platforms. Start with target-based configuration and keep generated files in a separate build directory from the source tree. Start with a small, representative task so you can check the results before extending the setup.

Use presets to record common configurations and test clean builds with the same compiler settings used in CI. Consider the practical trade-off: cMake language has a learning curve.

A few things you might be wondering.
