For general information on variables, see the Variables section in the cmake-language manual. When run in -P script mode, CMake sets this variable to the first command line argument. The asolute path of the active folder (e.g. cmake-variables - CMake Variables Reference This page documents variables that are provided by CMake or have mean- ing to CMake when set by project code. The CMake command used to build your project based on the currently selected Kit + Variant + Target. The full path to the directory where CMake cache files are located. You can change the value of these variables in your CMakeLists.txt to modify the behavior of CMake for your project. A list of common variables used internally by CMake can be seen here. Supports substitution for workspaceRoot, workspaceFolder, workspaceRootFolderName, userHome, $. To list all the variables that are defined and their current values, try this in a directory that has a CMakeLists.txt file: cmake -LAH. Specify location of the cmake executable.Ĭmake (causes CMake Tools to search the PATH environment variable, as well as some hard-coded locations.) (empty array-no cache initializer files) Passed to CMake via the -C command-line argument. Path, or list of paths, to cache-initialization files. Null (no environment variables specified)Īn array of additional arguments to pass to the underlying build tool. See Build Configurations for discussion of this and other related topics. Depending on the situation, the values in this variable may be treated case-sensitively or case-insensitively. Otherwise, the default value is generator-specific. Below you can find a sample CMake file with this functionality. Then, weâll use CMakeâs adddefinitions () function to set the corresponding preprocessor flag in our C++ program: Thatâs all there is to it. To build a single target, switch to CMake Targets View in Solution Explorer. If the CMAKECONFIGURATIONTYPES environment variable is set, its value is used. First, we will use CMakeâs option () function to add a command-line option when running the cmake command: cmake -DUSEDEBUGON. Its the same as running cmake -build -preset from the command line, where is the name of the active Build Preset.the root directory where CMakeCache.txt will be generated.)Īn object containing key:value pairs of environment variables, which will be passed only to the compiler. To build the entire project, select Build > Build All from the main menu. If true, build the launch/debug target before running the target. yes, but it comes with environment variables set up such that meson can. If 'false', your active folder only changes if you manually run the CMake: Select Active Folder command.Īn array of additional arguments to pass to cmake -build. Community edition and cmake installed build: ERROR: gnome Adjusting Build. ARCHIVEOUTPUTDIRECTORY property specifies the directory into which archive target files should be built. The CMAKEARCHIVEOUTPUTDIRECTORY variable is used to initialize the ARCHIVEOUTPUTDIRECTORY property on all the targets. See variable substitution, below, for more information about variable expansion. Please note that we are setting the same properties using different variables. In addition the cmakelists.txt is inside a subdirectory and referencing other sub scripts from there. Options that support substitution, in the table below, allow variable references to appear in their strings. Within the original cmake we have to edit quite a few own variables and reconfigure everytime after changing these kind of settings. This topic covers the available options and how they are used. In addition to the C++ compiler, we need Qt utilities like qmake, moc and rcc to build a Qt application. Starting with CMake 2.8.0, we extended the setproperty command to enable adding properties to CMake CACHE variables. We must set an environment variable SYSROOTS to /opt/imå/sdk/sysroots such that CMake knows where to find the host and target sysroot. With CMake 2.8 and later, it is now possible to present this elegantly with a drop-down combo box appearing for each such cache entry in cmake-gui. CMake Tools supports a variety of settings that can be set at the user, or workspace, level via VSCode's settings.json file. Similar to a list of enum values for you C++-heads.
