I just need to do some filesystem operation using #include <filesystem>, however, I get the below link error ... I guess I am missing a library in the xlink command. Below is the error message.
Please let me know your valuable comments.
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)

Edit
Below you can see the compile and link commands. (thx)

I raised the problem with Intel C++ Community here and it turns out to be a reproducible issue, and they suggested to update my VS 2019 Community Edition. I updated to 16.8.5 and it worked. So may be it is probably the right solution. (at least worked for me.)
