hmm. i'm using pybind11 2.5.0 all on slackware 14.2 (64bit) the errors i 
get with openimageio are....

See also "/tmp/SBo/oiio-Release-2.0.13/build/CMakeFiles/CMakeError.log".

looking at the CMakeEerror.log the complaint is that pthread_create does 
not exist.
gcc is 5.5, the latest for 14.2 and in /usr/include/pthread is
extern int pthread_create (pthread_t *__restrict __newthread,
                            const pthread_attr_t *__restrict __attr,
                            void *(*__start_routine) (void *),
                            void *__restrict __arg) __THROWNL __nonnull 
((1, 3));

so there is at least a function declaration.

the only thing in my setup/config I can think of that might be different 
is i'm using ffmpeg4 rather than ffmpeg3
