Mastering C++20 Modules with CMake

Explore the fundamentals and advanced implementation of C++20 modules in this comprehensive conference talk from CppCon 2024. Learn practical techniques for building both shared and static libraries using CMake's newly released non-experimental support for C++20 modules. Discover how to set up build files, organize source code with modules, and examine real-world open-source module projects. Master the "import std" model and understand how to create module interfaces for large existing libraries, facilitating a transition to modular codebases. Gain insights into the current state of module support across major compilers including Visual Studio, Clang, and GCC, while learning essential strategies for integrating C++20 modules into development workflows. Benefit from the expertise of Bill Hoffman, CMake's original author and lead architect, as he shares over 20 years of experience in large software systems development and provides hands-on techniques for leveraging this cutting-edge feature to enhance modern C++ codebases.
