I use to build UE4.19, found there are two compiling errors:
NvClothIncludes.h(14) error C2059: syntax error: ‘)’
NvClothIncludes.h(50) error C2059: syntax error: ‘)’

the code is:
PUSH_macro(check)

I do not know how to fix it, do you know about it EricFriedman

This is actually a bug of visual studio. See pragma push_macro error on visual studio 2015 · Issue #256 · fastbuild/fastbuild · GitHub
