I believe QT should be invoking MASM (ml64.exe) on x64masm.asm
(http://github.com/weidai11/cryptopp/blob/master/x64masm.asm).
According to the cryptlib.proj, it should be invoked with the following
defines
(https://github.com/weidai11/cryptopp/blob/master/cryptlib.vcproj#L8658):
/D_M_X64 /Zi
Another option is to have Qt set CRYPTOPP_DISABLE_ASM to disable all the
assembly language routines.
