Package build2

https://build2.org/

build2 is an open source (MIT), cross-platform build toolchain for developing
and packaging C++ code. It is a hierarchy of tools that includes the build
system, package dependency manager (for package consumption), and project
dependency manager (for project development). Key features:

 * Next-generation, Cargo-like integrated build toolchain for C++.
 * Covers entire project life cycle: creation, development, testing, and
   delivery.
 * Uniform and consistent interface across all platforms and compilers.
 * Fast, multi-threaded build system with parallel building and testing.
 * Archive and version control-based package repositories.
 * Dependency-free, all you need is a C++ compiler.
