## What it is
Cotire is a CMake module that speeds up C/C++ builds by automatically setting up precompiled headers and single compilation unit (unity) builds for CMake targets. It requires no source code changes and works with Clang, GCC, Intel, and Visual Studio compilers.

## Use cases
- speed up cmake builds with precompiled headers
- set up unity builds for a cmake project
- reduce compile times for large c++ codebases
- automatically generate prefix headers from includes
- accelerate builds without modifying source code

## When to choose
- maintaining a legacy project on CMake older than 3.16 that needs faster builds
- you want automated precompiled header and unity build setup with minimal CMake changes

## When to avoid
- using CMake 3.16 or newer, which has built-in precompiled header and unity build support
- you need active maintenance or support for new compilers/generators

## Facets
- artifact type: library
- maturity: abandoned
- function: build-tool, developer-tools
- domain: developer-tools, performance, compilers
- platform: windows, cpp, c
- tags: cmake, precompiled-headers, unity-builds, build-acceleration, linux, macos
