+## CMake Presets
+
+The `CMakePresets.json`; see [cmake-presets(https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html)
+
+- Cross-platform and cross-IDE.
+
+- Standardized CMake feature (since CMake 3.19+, recommended after 3.21).
+
+- Works in Visual Studio, VS Code, CLI, CI systems, etc..
+
+## Visual Studio Settings
+
+There's also a Visual Studio specific file: `CMakeSettings.json`. This the file that supports the GUI CMake settings.
+
+See the Microsoft [CMakeSettings.json schema reference](https://learn.microsoft.com/en-us/cpp/build/cmakesettings-reference?view=msvc-170)
+
+## Visual Studio (2022 v17.1 and later):
+
+- Prefers `CMakePresets.json` if it exists.
+
+- Falls back to `CMakeSettings.json` if no presets are found.
+
+- Lets you override or extend presets via `CMakeSettings.json`.
+
+### Recommendations:
+
+- Use `CMakePresets.json` to define shared, cross-platform presets.
+
+- Use `CMakeSettings.json` to define Visual Studio-specific overrides, like:
+  * Custom output directories
+  * Specific environment variables
+  * *UI-related tweaks
