## What it is
CPM.cmake is a small CMake script that adds setup-free, cross-platform dependency management to CMake projects. It wraps CMake's FetchContent module with version pinning, caching, and a simple CPMAddPackage API.

## Use cases
- manage c++ dependencies without installing a package manager
- pin dependency versions reproducibly in cmake
- fetch github projects directly into a cmake build
- avoid vcpkg or conan setup for small projects
- cache dependencies across builds to speed up ci

## When to choose
- your project uses modern cmake and you want zero-setup dependency management
- you want reproducible builds with version-controlled dependencies
- you want to consume any git repo or downloadable source as a dependency without packaging it

## When to avoid
- you need prebuilt binaries or a large curated package ecosystem
- your team already standardizes on vcpkg, conan, or system packages
- you need dependency resolution with complex version constraint solving

## Facets
- artifact type: library
- maturity: active
- function: package-manager, build-tool, developer-tools
- domain: developer-tools, cross-platform, version-control
- platform: windows, cpp, cross-platform
- tags: cmake, dependency-management, fetchcontent, reproducible-builds, c-plus-plus, linux, macos
