From: "Guillaume W. Bres" <redacted> 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. Signed-off-by: Guillaume W. Bres <redacted> --- Warning!!: this new package and its internal BR2_PACKAGE_PYBIND11_WITH_PYTHON option intends to replace package/python-pybind which is totally broken since upgrade to v2.6.1 in ->next. The python build now requires a previous cmake build: + python-pybind only is not possible and will not build by itself + python setup.py requires cmake to install within $(@D) a couple files (in $(@D)/pybind11 exactly) to properly work. See my message in BR digest 17/02: [ref] cc to Thomas, Gwen & Peter, entitled: "Python-pybind we need to discuss this package" => If this package is merged, package/python-pybind is deprecated => package/python-pybind v2.6.1+ in ->next must be removed, python-build by itself cannot work anymore Pybind11 is a host only package Signed-off-by: Guillaume W.
