Introducing the Qt Project CMake Skill for AI Agents

The Challenge: CMake and Qt - Powerful Together, Tricky in Practice

The gap between “CMake that compiles” and “CMake that is correct” can be sometimes significant. CMake has been Qt’s official build system since Qt 6.0, and the pairing is genuinely capable: a well-configured Qt CMake project supports cross-platform builds, incremental QML compilation, seamless C++/QML integration, and deployment-ready install targets. But getting there requires mastering a build API that has evolved rapidly across Qt 6 minor releases - and that evolution is precisely where things can become challenging for Large Language Models, especially older or smaller models.
