Modify automatic configuration and cache notificationsīy default, Visual Studio automatically invokes configure each time the active Target System or Configure Preset changes. In the table, " Tools > Options enabled" means Use CMakePresets.json to drive CMake configure, build, and test is selected in Tools > Options > CMake > General. If no configuration file is present, default Configure Presets are used. The following table indicates when CMakePresets.json is used instead of CMakeSettings.json to drive CMake configuration and build in Visual Studio 2022 and Visual Studio 2019 version 16.10 and later. In some older versions of Visual Studio, Tools > Options > CMake > General only has a single option to enable CMakePresets.json integration: You can enable it in Tools > Options > CMake > General:Ĭlose and reopen the folder in Visual Studio to activate the integration. Enable CMakePresets.json integration in Visual StudioĬMakePresets.json integration isn't enabled by default in Visual Studio. We recommend using at least CMake version 3.14 or later. So, CMake version 3.20 or later isn't strictly required when you're building with CMakePresets.json inside Visual Studio. However, Visual Studio reads and evaluates CMakePresets.json and CMakeUserPresets.json itself and doesn't invoke CMake directly with the -preset option. For an example and more information, see CMakePresets.json format.ĬMake version 3.20 or later is required when you're invoking CMake with CMakePresets.json from the command line.

You can update the version by changing the "version" field in the root object.

Visual Studio 2022 version 17.4 preview 2 adds support for schema versions 4 and 5.

Visual Studio 2019 version 16.10 and later support schema versions 2 and 3.

The supported CMakePresets.json and CMakeUserPresets.json schema versions depend on your version of Visual Studio: Supported CMake and CMakePresets.json versions

To enable or disable CMakePresets.json integration in Visual Studio, see Enable CMakePresets.json in Visual Studio 2019. Visual Studio never reads from both CMakePresets.json and CMakeSettings.json at the same time. We recommend CMakePresets.json as an alternative to CMakeSettings.json.

For more information about how to use CMakePresets.json in Visual Studio Code, see Configure and build with CMake Presets.

For more information about the Microsoft vendor maps and macro expansion, see CMakePresets.json and CMakeUserPresets.json Microsoft vendor maps.

For more information about the format of CMakePresets.json, see the official CMake documentation.

This article contains information about CMakePresets.json integration with Visual Studio. Both files are supported in Visual Studio 2019 version 16.10 or later. CMakeUserPresets.json is for developers to save their own local builds. Use these files to drive CMake in Visual Studio and Visual Studio Code, in a continuous integration (CI) pipeline, and from the command line.ĬMakePresets.json is for saving project-wide builds. So, next build won't treat the file as updated and won't trigger the COMMAND re-run.CMake supports two files that allow users to specify common configure, build, and test options and share them with others: CMakePresets.json and CMakeUserPresets.json. That is, if the variable is set by a user to another value, then options_list_file will be updated, and this triggers re-running custom COMMAND on next build.īut if the variable's content is not changed, then configure_file wouldn't change the file options_list_file and its timestamp (this is important!). This is a main feature of configure_file. Upon that re-run the configure_file will be called unconditionally.īut the file options_list_file will be updated only when its content would be changed.
