Build fails due to invalid flags in the generated .vcxproj -- on first glance looks like LLVM tools' flags are passed to MSVC tools.

LINK : warning LNK4044: unrecognized option '/flto=thin'; ignored [D:\a\node-blake2\node-blake2\build\blake2.vcxproj]
LINK : fatal error LNK1117: syntax error in option 'opt:lldltojobs=2' [D:\a\node-blake2\node-blake2\build\blake2.vcxproj]

The flag was added in nodejs/node#63114 /cc @StefanStojanovic
