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. 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. what version of the C++ extension do you have installed starball 2 days ago yes I used Visual Studio Code. drescherjm 2 days ago 2 sounds like this issue: /microsoft/vscode-cpptools/issues/. Because I have different versions of my static libraries that is used on Debug and Release versions. I am working on a CMake project that need to set specific paths for each configuration type (e.g., RELEASE, DEBUG, MINSIZEREL and RELWITHDEBINFO) for a static library in linking process. This file provides command-line arguments and environment variables that are passed to CMake when you build the projects. CMake should not be involved in the execution of your program or the debugger arguments. CMake conditional for Release,Debug and Etc. 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. If -DCMAKE_BUILD_TYPE=Debug is not passed, CMAKE_BUILD_TYPE is empty, and none of the extra CMAKE_CXX_FLAGS_XXX values are added, so we end with a build without -g.Visual Studio uses a CMake configuration file to drive CMake generation and build. Flags used by the CXX compiler during RELWITHDEBINFO builds.ĬMAKE_CXX_FLAGS_RELWITHDEBINFO:STRING=-O2 -g -DNDEBUG Flags used by the CXX compiler during RELEASE builds.ĬMAKE_CXX_FLAGS_RELEASE:STRING=-O3 -DNDEBUG Flags used by the CXX compiler during MINSIZEREL builds.ĬMAKE_CXX_FLAGS_MINSIZEREL:STRING=-Os -DNDEBUG Flags used by the CXX compiler during DEBUG builds. That command also shows other values of interest which clarify the default behavior across built types: // Flags used by the CXX compiler during all build types. Flags used by the C compiler during DEBUG builds. Which gives: // Flags used by the CXX compiler during DEBUG builds. The default values of CMAKE_C_FLAGS_DEBUG and CMAKE_CXX_FLAGS_DEBUG can be found as mentioned at: with: cmake -LAH. If you would really like to explicitly control the build flags for the debug you can also set them with cmake -DCMAKE_BUILD_TYPE=Debug O0 is not added by default to the Debug build, but -O0 is the default -O value as mentioned at: and on man gcc, so it normally doesn't matter. When CMake execution fails on your project, press Explain with AI in the CMake tool window to get a better understanding what has gone wrong and how to fix it: GIF For Python code in CLion, you can also benefit from the Generate documentation action and name suggestions from the AI Assistant when renaming symbols. Which shows the GCC build commands as explained at: ĭoing that adds the -g flag as can be confirmed with: make VERBOSE=1 At invocation time, normally all that you need to make a debug build with CMake is: cmake -DCMAKE_BUILD_TYPE=Debug.
