pybind11 is a lightweight header-only library that exposes C++ types \
in Python and vice versa, mainly to create Python bindings of existing \
C++ code.

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.
# Whenever python3.X-pybind11-devel is introduced, it needs to explicitly
# conflict with all the previous python3.X-pybind11-devel packages as well as
# the non-namespaced pybind11-devel package from the main Python stack.
Conflicts:  pybind11-devel < %{version}-%{release}
