Doesn't build on Windows + MSVC

[quartzsaber]

Installing cysimdjson using pip on Windows with MSVC fails.

It is due to MSVC not understanding the compiler flag -Wno-deprecated when compiling cysimdjson.cpp.

Also, MSVC won't understand -std=c++17 and will ignore the flag (and use C++11). The syntax for MSVC is /std:c++17.

Here is the relevent error log:

I am facing the same issue, Is this repo active?

I can confirm that this issue still exists as of October.

#40 I came up with a possible solution for windows users that I think may help solve this problem. turns out the flag for windows is called /std:c++17 This flag allows for windows to compile the code correctly
