Configcmake

Configcmake is a lightweight open‑source utility designed to streamline the process of generating and managing CMake build scripts for C++ projects. Developed as a response to the growing complexity of large CMake configurations, the tool automates routine tasks such as setting up standard build targets, handling dependency discovery, and applying project‑wide conventions for compiler flags and testing frameworks. Unlike traditional CMake usage, Configcmake offers a higher‑level interface that can be invoked through simple command‑line arguments or invoked programmatically from Python or shell scripts. The core of Configcmake is a domain‑specific language that extends the CMake syntax, providing additional macros for automatic source discovery, conditional inclusion of modules, and configuration of cross‑platform toolchains.

Users of Configcmake generally integrate it into their repository’s root by placing a configcmake.yaml file that specifies project metadata, build variants, and dependency lists. Running the command `configcmake generate` will produce a complete CMakeLists.txt file that respects the provided settings, which can then be used directly by the standard `cmake` tool. The tool also supplies a validation step (`configcmake validate`) that checks that the generated build scripts satisfy common coding standards and that all declared dependencies are available on the target system.

The project is hosted on GitHub under an MIT license, and its community includes developers from both academic and commercial sectors. Regular releases are accompanied by comprehensive documentation and examples on how to convert existing projects to using Configcmake. Its modular architecture allows extensions via plugins, enabling users to tailor the generation logic to niche build environments or integrate with continuous‑integration pipelines.
