Configuring the visibility of pybind11 objects without global effect

[charlie0389]

I note that in the documentation here, it is recommended to use the -fvisibility=hidden option when compiling code that uses pybind to eliminate the 'declared with greater visibility than the type of its field' warning.

However, that approach affects compilation project wide, and I'd prefer that the '-fvisibility=hidden` option only have an affect on Pybind objects. How can this be achieved?

Please note that an approach like this does not compile:

#pragma gcc push visibility(hidden)
#include <pybind11/embed.h>
#pragma gcc pop

And an approach like this does not work either:

#pragma GCC visibility push(hidden)
    pybind11::module_ py_mod; // Offending declaration
#pragma GCC visibility pop

Note that a more illustrative explanation/example of the underlying issue can be found at stackoverflow.
