An Introduction to CMakePresets.json
summary
CMakePresets.json arrives in CMake 3.19/3.20 and provides repository-checkin cmakepresets.json plus per-user cmakeuserpresets.json to replace ad hoc shell/batch scripts for configure build and test. Configure presets (3.19) and build/test presets (3.20) set generator (Ninja, VS, Xcode), cache variables, inheritance, targets and parallelism; CLI, CMake GUI, VS Code (CMake Tools v1.7) and Visual Studio (16.10 preview) integrations demo successfully, with vendor map entries for IDE-only options and a noted Visual Studio caveat around multi-config generators.
