UnrealEngine-VXGI2-4.21 Compile Error


I’ve been trying to install Unreal Engine VXGI2.4.21 which i’ve downloaded from Github on VXGI branch. I am relatively new on compiling with Visual studio 2019. I followed the instructions as per the readme file, but everytime I try to compile, i’ve been getting this following errors as per attached screenshot.

Anyone has any idea? i’am lost of words after multiple try. Do I have to use Visual studio 2017 to install this build? If so where can I download them.
