error LNK2019 when call text_extent_size in vs2017

[yinkaisheng]

The solution complies without any errors. However, if I add the following code std::string hw = "Hello, world!"; auto hw_size = graph.text_extent_size(hw); to a_group_impl.cpp dw.draw, it can't compile successfully. because nana.vcxproj has the option /std:c++latest, but other projects don't have /std:c++latest. _nana_std_has_string_view is not defined without /std:c++latest.

Yes, sorry. I was updating... I will fix it today. You have to select all the projects and set the same option for all.
