A subsequent build is likely to overwrite object files produced by the earlier configuration. release libs for the release target and debug libs for the debug target of course. What I want to do is define libraries and library directories for the Debug and Release target independently, i.e. Then add the additional debug and optimizations for the libraries that you want. Its project files are generated by CMake. How to configure for a debug build or a release build. Dont set CMAKEBUILDTYPE keep it blank or make a custom one where you set exactly what you want the base flags to be. 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. How to see compile flags and definitions and how to control them. Generators that do only support a single configuration (like Unix Makefiles) work differently. Performs Bazel Target Diffing between two revisions in Git. 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. CLI tool to build, test, debug, and deploy Serverless applications using AWS SAM. 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. The possible alternative in addition to CMake generator expression is performing this not via CMake, but directly from the MSVC compiler: First, you may want to detect that youre using the MSVC toolchain. How configurations are handled depends on the generator that is being used. I personally do not use a lot CMake generator expressions. MinSizeRel: A special Release build optimized for size.RelWithDebInfo:: Same as Release, but with debugging information.Each target corresponds to an executable or library, or is a custom target.
