Pybind11 (global install marker)

Pybind11 is a C++ header-only library that provides seamless interoperability between C++ and Python, enabling the creation of Python bindings for C++ code and vice versa. The `pybind11-global` PyPI package, version 3.0.3, typically serves as a marker or a convenient way to ensure the necessary pybind11 C++ headers are discoverable for projects building Python extensions. Pybind11 maintains an active release cadence, with major versions introducing significant features and ABI bumps, followed by patch releases for bug fixes and compatibility updates.
