When the command must be executed always the target is built. When is a good idea to run a command in add_custom_target? If the custom command contains also a command, it will be executed always and after running the custom command.Įach time we need to run a command to do something in our build system different to build a library or an executable. Important: if a custom target depends on a custom command, the custom target will run the custom command. why do you need to regenerate all that code.
Why is this useful? Imagine that you have to call a program to generate code. Each time the source_file file placed in the source directory is modified.In this case, the custom command will be run: 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.Enter fullscreen mode Exit fullscreen mode 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.
