For example, this builds the build target X. A subsequent build is likely to overwrite object files produced by the earlier configuration. If your generator is a single-config generator like 'Unix Makefiles' or 'Ninja', then the build type is specified by the CMAKEBUILDTYPE variable, which can be set in the configure command by using -DCMAKEBUILDTYPE:STRINGRelease. CMake gives a features of building the generated project by using -build command argument. Here the currently active configuration is determined by the value of the CMake variable CMAKE_BUILD_TYPE.įor example, to pick a different build type one could issue the following command line commands: cmake -DCMAKE_BUILD_TYPE=Debug path/to/sourceĬmake -DCMAKE_BUILD_TYPE=Release path/to/sourceĪ CMake script should avoid setting the CMAKE_BUILD_TYPE itself, as it's generally considered the users responsibility to do so.įor single-config generators switching the configuration requires re-running CMake. Generators that do only support a single configuration (like Unix Makefiles) work differently. CMake will generate all configurations at once and you can select from the IDE or. For these generators CMake will try its best to generate a build directory structure such that files from different configurations do not step on each other. Learn cmake - Switching between build types, e.g. There are a few project configuration settings you can change by either editing the CMakeCache.txt file (or using some GUI to do this), or from the command line. CMake will generate all configurations at once and you can select from the IDE or using -config CONFIG (with cmake -build) which configuration you want to build. Some generators (like Visual Studio) support multiple configurations. How configurations are handled depends on the generator that is being used. make CMakeLists.txt SET (CMAKEBUILDTYPE 'Debug) or SET (CMAKEBUILDTYPE 'Release') 2018.05. make mkdir Debug cd Debug cmake -DCMAKEBUILDTYPEDebug.

Release: Your typical release build with no debugging information and full optimization.Debug: Usually a classic debug build including debugging information, no optimization etc. CMake knows several build types, which usually influence default compiler and linker parameters (such as debugging information being created) or alternative code paths.īy default, CMake is able to handle the following build types:
