cotire
A CMake module that automates precompiled headers and single compilation unit builds to speed up C/C++ compilation.
What is cotire?
Cotire is a CMake module that speeds up the build process of C and C++ projects by automating precompiled header generation and single compilation unit (unity) builds. It reduces compilation times by optimizing how headers are processed and enabling faster unity builds, though its functionality has been superseded by native features in CMake 3.16 and later.
C and C++ developers using CMake as their build system, particularly those working on large projects with heavy header usage or seeking to reduce build times without modifying source code.
Developers choose Cotire for its non-intrusive automation of build optimizations, cross-compiler support, and compatibility with existing CMake workflows, offering significant speed improvements with minimal configuration.
