I don't think that's a problem - I see the same pthread problem  in
CMakeError.log of a successful build.

How old is your pybind11 build? In February I updated the SLackBuilkd
for pybind11, the main change being to use CMake instead of Python as
the build instrument; also to use python3 exclusively instead of
python2. I suggest you rebuild/install this latest pybind11, then try
openimageio again.
