Can't do a fresh pip install from source distribution: pybind11 issues. #278
Description
On macOS, 10.12.6 w/ a fresh Python 3.7 virtualenv with pip 19.0.3, pip install pyopencl must download the 2018.2.3 source package, given that none of the 2018.2.4 manylinux wheels match.'
The setup script ultimately fails due to pybind11 not being found. It looks like it's being included via setup_requires which uses easy_install if I recall. If I easy_install pybind11 beforehand, check_pybind11() passes, but the missing header error still happens in install. Only if I pip install pybind11 beforehand does the install succeed.
$ pip install pyopencl
