Error C4503 with boost

Hello.
I have the C4503 error in VS2015 including external libraries. I’m trying to include websocketpp that uses boost libs.
Furthermore, C4503 is a warning by default, but in UE 4.12, it causes a compile error.

The problem is the same of

but solutions have been given there.

[SOLVED] Solution of Steve Robb, STAFF:
You can disable particular cl.exe warnings by adding an entry to WindowsPlatformCompilerSetup.h

I simply removed C4503 as error from that file and ignored.
