To properly build, debug and test the project, search for the following extensions and install them. Open VSCodium and navigate to the Extensions tab. These are the operations that you are likely to perform and the examples above can act as templates. First, go to their website and download the latest installation package for your system. The examples above provide a short and practical introduction to CMake and how it can be used to build: a simple project, a separately compiled project, and a shared library. If you haven't already experience with VSCodium or VS Code, this example project is a good starting point. With the information available in the CMakeLists.txt, IDEs like VSCodium can configure the build system accordingly. We also specify the scope of this property to be of type INTERFACE: This means that the property will only affect build targets that link against this library, not the library itself. First, run the cmake executable or the cmake-gui to configure the project and then build it with your chosen build tool. With the statement target_include_directories(.), we add the current subdirectory to the search path for header files for other build targets. With add_library(.) we define a new build target: The static Generator library. Examples CMake The following example demonstrates some key ideas of CMake. Producer.cpp int main(int argc, char** argv)) Compile examples Examples are on GitHub here and their links are mentioned in each section as well. In the main() function of our executable, we just process the input parameter and exit the program if no one value (or a value that can't be processed) is provided. you have CMake v3.23 on your machine, you have a compiler like GCC, Clang, Intel, or MS Visual C++ installed on your operating system. Use the linker (link.exe) to link compiled. Our sample program is a simple command-line tool: It takes an integer as an argument and outputs numbers randomly shuffled in the range from one to the provided input value. Use the compiler (cl.exe) to compile and link source code files. In addition, the configuration described in the CMakeLists.txt can be read by many editors like QtCreator, VSCodium/VSCode, or Visual Studio. When CMake processes this file, it automatically detects the installed compilers on your systems and creates a working Makefile. This information gets made available to CMake in the file CMakeLists.txt using a special description language. At a high altitude, you define the individual parts of your project (executables, libraries), compiling options (C/C++ standard, optimizations, architecture), the dependencies (header, libraries), and the project structure on file level. What sounds simple at first glance can be pretty complex at second glance. Why CMake?ĬMake is a build system generator that creates the Makefile for your project. I've tested the steps described in this article. As usual, the related example code is available on GitHub. In this article, I will prepare a C/C++ build system based on CMake and VSCodium. Aside from that, it will be easier for you to get others involved in your project. If you build up your project from the beginning on a powerful toolchain, you will benefit from a faster and safer development. This article is part of a series about open source DevOps tools for C/C++ development.
