Windows 10, ICL 19.1.2.254 Build 20200623: What is the library to use filesystem header ?

[mikeitexpert]

I need to use `include <filesystem>` in my code, however, I get the below link error as I build my application. My target platform is Windows 10 64bit. 

test_accuracy.obj : error LNK2019: unresolved external symbol wmemcmp referenced in function "public: class std::filesystem::path & __cdecl std::filesystem::path::operator/=(class std::filesystem::path const &)" (??_0path@filesystem@std@@QEAAAEAV012@AEBV012@@Z)
Debug\test_accuracy.exe : fatal error LNK1120: 1 unresolved externals

I just have no idea what library I need to pass to the xlink. 

Your comments are much appreciate it.

Hi,

Thank you for your patience. We worked with a reproducer code and the issue was reproduceable in Visual studio. But the same code worked fine in command line. The issue seems to be related to Visual studio. We urge you to try executing your code after upgrading your visual studio. If the issue persists, please raise your issue in Microsoft Visual Studio forum.

I updated my VS  2019 16.8.5 and it worked just fine.

Thanks for the clue.
