Summary:  Development headers for pybind11

# This package does not have namespaced file locations, so if we build the
# pybind11-devel subpackage in any other stack as well, the files from these
# packages will conflict. The package name is namespaced so that customers can
# decide which to install, but the packages will conflict with each other.
