Different commands, such as building and debugging the code, are also available from the context menu for the CMakeLists.txt files. The main menu contains an additional item called CMake with different commands, such as building the scripts, managing the CMake cache, changing the CMake settings and others. When you open a folder, you can see the contents of that folder, including the CMakeLists.txt file(s) in the solution explorer. To open the code from such a directory, go to File > Open > Folder. If your code is split across multiple projects and sub-directories, you need to have one in each project directory. For that, you need to have a CMake script, always called CMakeLists.txt, in the same location with your sources. In Visual Studio 2017, you can open C++ code by using the open folder feature. For an in-depth discussion of the support, see CMake support in Visual Studio. Overview of Support in Visual Studio 2017Īlthough this article is an introduction to CMake, it makes sense to start with a brief walk-through of the support for it in Visual Studio. This article provides an introduction to CMake through a series of examples to help you, as VC++ developers, to create and maintain CMake projects. This means it is possible to create, edit, build, run and debug C++ code in Visual Studio 2017 without the need to explicitly generate VC++ projects, as that is taken care behind the scenes by the system. Although CMake has had support for all versions of Visual Studio, starting with version 6, Visual Studio 2017 is the first version to support CMake. CMake uses scripts (called CMakeLists.txt) to generate environment specific build files, such as Visual Studio projects, XCode projects, make scripts and others. CMake is a cross-platform open-source tool for defining the build process for native applications independently of compilers and environments. JSON IntelliSense helps you edit the CMakeSettings.json file:įor more information about each of the properties in the file, see CMakeSettings.json schema reference.One of the important changes in Visual Studio 2017 for native development is support for CMake. This name appears in the C++ configuration dropdown. The following settings are available under the General heading: Configuration nameĬorresponds to the name setting. Visual Studio never modifies CMakeLists.txt automatically by using CMakeSettings.json you can customize the build through Visual Studio while leaving the CMake project files untouched so that others on your team can consume them with whatever tools they're using. This file provides command-line arguments and environment variables that are passed to CMake when you build the projects. The options that you choose in the editor are written to a file called CMakeSettings.json. The settings that you see in the editor might vary depending on which configuration is selected. You can add more configurations by choosing the green plus sign. Visual Studio provides one 圆4-Debug configuration by default. Now you see the Settings Editor with the installed configurations on the left. To open the CMake settings editor, select the Configuration drop-down in the main toolbar and choose Manage Configurations. However, if you prefer to edit the file directly, you can select the Edit JSON link in the upper right of the editor. It's intended to be a simpler alternative to manually editing the CMakeSettings.json file. The editor lets you add CMake configurations and customize their settings easily. If you maintain projects that use a CMakeSettings.json file for CMake build configuration, Visual Studio 2019 and later versions provide a CMake settings editor. For more information on CMakePresets.json, see Configure and build with CMake Presets. CMakePresets.json is supported directly by CMake and can be used to drive CMake generation and build from Visual Studio, from VS Code, in a Continuous Integration pipeline, and from the command line on Windows, Linux, and Mac. CMakePresets.json is supported by Visual Studio 2019 version 16.10 or later and is the recommended CMake configuration file. Visual Studio uses a CMake configuration file to drive CMake generation and build.
