Prefab is a tool for generating build system integrations for prebuilt C/C++ libraries. A Prefab package consists of a small amount of metadata and the prebuilt libraries it describes. Prefab is:
Build system agnostic. Build system support is provided via a plugin API, so it's simple to provide support for any build system not supported out of the box.
Cross-platform capable. Prefab currently handles only Android libraries, but is designed to handle any number of platforms.
Distribution agnostic. Prefab is only an archive format, and can be distributed with whatever package management infrastructure best fits your use case. Android packages will commonly be distributed within an AAR via Maven to be easily used in an Android Gradle project, but distribution as a tarball or a git submodule would work just as well.
