Under MSVC we were ignoring PYBIND11_CPP_STANDARD and simply not passing any standard (which makes MSVC default to its C++14 mode). MSVC 2015u3 added the `/std:c++14` and `/std:c++latest` flags; the latter, under MSVC 2017, enables some C++17 features (such as `std::optional` and `std::variant`), so it is something we need to start supporting under MSVC. This makes the PYBIND11_CPP_STANDARD cmake variable work under MSVC, defaulting it to /std:c++14 (matching the default -std=c++14 for non-MSVC). It also adds a new appveyor test running under MSVC 2017 with /std:c++latest, which runs (and passes) the `std::optional`/`std::variant` tests. Also updated the documentation to clarify the c++ flags and add show MSVC flag examples. |
