D:\tmp\CMake-VisualStudio-Example> cd _build Make the build directory the current working directory. D:\tmp\CMake-VisualStudio-Example> mkdir _build Source StructureĪs recommended earlier, for an out of source build, create a directory where CMake will produce the required Visual Studio Project files and a lot of CMake specific files. For those not familiar with Git, GitHub has an option to download it as a zip file. The example code can be accessed via GitHub at. Here, it has been enhanced to show specific aspects commonly used on Windows. Please refer to it if you are not familiar with the basics. The tutorial from CMake is a very simple example. Properties->Linker->Input->Additional Dependencies Properties->Linker->General->Additional Library Directories Properties->C/C ->General->Additional Include Directories Properties->C/C ->Preprocessor->Preprocessor Definitions Set_target_properties(PROPERTIES RUNTIME_OUTPUT_DIRECTORY) Target name in the command add_executable or add_library Some common Visual Studio project operations and settings and its mapping to CMake is listed below as an overview. In a CMake build system, the build “rules” or “project settings” are defined in text files called CMakeLists.txt. To clean or reset your build environment, you would simply delete the out of source build directory. However, with CMake you can consider this to be an intermediate file too, as CMake will generate it and is recommended for it to be outside the source directory. sln) as a “source” since it involves adding/removing source files, modifying library dependencies, setting build dependencies etc. These need not (and should not) be checked into the source repository as sometimes they are large and user specific.Ī Visual Studio developer might consider the project file (. obj, Visual Studio produces many more transient files like. Other than the typical intermediate files like. A build will always generate a lot of temporary/intermediate files and to avoid polluting the actual source, it is recommended to have out of source builds. Anything that is or can be consistently generated from the source files should be considered as output of the build process. Typically source should be considered as any files that are explicitly modified by the developer. Continuing from the preface CMake for Visual Studio Developers. Most references here is based on Visual Studio 2010 but will apply equally well to other versions. It is primarily intended for a C developer using Visual Studio. This post will map CMake commands to the Visual Studio IDE with an example which makes learning much easier. With the built-in support you have a direct view onto your directory structure, have to bother less about IDE-specific things and can leverage many nice features like presets or faster builds with Ninja.CMake produces Visual Studio solutions seamlessly. But since Visual Studio has built-in support for CMake since 2015 (IMHO pretty decent one since 2019), I would recommend using that instead of generating solution and project files. for plugins) then once you intend to package/install your artifacts you need to use the $ and $ generator expressions as documented for the target_include_directories() command.įor managing the folder structure of the generated Visual Studio project have a look at the source_group() command. If your building a library instead or your executable provides any INTERFACE/ PUBLIC headers (e.g. Then setting the include paths should be as easy as: target_include_directories(Engine PRIVATE "$") I assume you are building an executable (because of main.cpp) and that your CMakeLists.txt resides in the Engine/ directory.
