import CMake, CMake and C++20 Modules - Bill Hoffman - CppCon 2022

Learn how CMake is evolving to support C++20 modules, improving build and installation of projects, and enhancing configurability with its testing and installer systems.

Key takeaways

CMake’s goal is to give compile-time portability, and it has been successful in achieving this.
CMake has been used in many projects, including ITK, a C++ library.
CMake is now working on supporting C++20 modules, which will allow for easier build and installation of projects.
CMake’s experimental CXX module API allows for the creation of C++ modules, which can be used to create libraries and executables.
The CXX module API uses a JSON file to store the module’s metadata and dependencies.
CMake has improved its file-based API to support C++ modules, including the ability to install and uninstall modules.
CMake has also improved its support for system include directories and has added support for Ninja, a build system.
CMake’s C++ module support is still experimental, but it is expected to be fully supported in the future.
CMake’s build system is designed to be highly configurable and can be used to build a wide range of projects.
CMake’s installer is also highly configurable and can be used to create installers for a wide range of platforms.
CMake’s testing system, ctest, is also highly configurable and can be used to run tests on a wide range of platforms.
CMake’s support for C++20 modules is still experimental, but it is expected to be fully supported in the future.
CMake’s support for C++ modules is not limited to C++20, but it will also support C++17 and C++14 modules.
CMake’s support for C++ modules is not limited to the C++ standard library, but it will also support third-party libraries and frameworks.
CMake’s support for C++ modules is not limited to the build system, but it will also support the testing system and the installer.
