cpp cppcon import CMake Mastering C Modules - Bill Hoffman - CppCon 2024 Slides: --- C20 modules represent a significant advancement in the language promising to improve compile times enhance code organization and streamline dependency management. This talk is tailored for developers eager to harness the power of C20 modules in their projects. We will explore the fundamentals of building both shared and static libraries using CMake the de facto build system for C. Attendees will gain practical insights into setting up build files and organizing source code with modules. We will dissect real-world open-source module projects offering a concrete understanding of how modules are being used in the wild. A key focus will be on the import std model demonstrating how to create a module interface for large existing libraries facilitating a smoother transition to modular codebases. Significantly CMake released non-experimental support for C20 modules in October 2023 marking a pivotal moment for developers. Visual Studio Clang and GCC all have some level of support for modules. However the adoption of this feature is still in its early stages with relatively few projects currently leveraging it. This session will bridge that gap providing the essential knowledge and hands-on techniques to confidently integrate C20 modules into your development workflow. By the end of this session participants will be equipped with the knowledge to effectively use CMake for building projects with C20 modules making the most of this cutting-edge feature to enhance their codebases. Whether youre maintaining legacy code or starting a new project this talk will provide the essential tools and techniques to master C20 modules. --- Mr. Hoffman is a founder of Kitware and currently serves as Chairman of the Board Vice President and Chief Technical Officer CTO. He is the original author and lead architect of CMake an open source cross-platform build and configuration tool that is used by hundreds of projects around the world and he is the co-author of the accompanying text Mastering CMake. Using his 20 years of experience with large software systems development Mr. Hoffman is also a major technical contributor to Kitwares Visualization Toolkit Insight Toolkit and ParaView projects. ,
