Failed to build with VS2015.

[Gauravkohli1796]

I tried to build this project with VS2015.By passing -G "Visual Studio 14 2015 Win64" -DCMAKE_GENERATOR_TOOLSET=v140 -DCMAKE_SYSTEM_VERSION=8.1 flag and curl and boost paths along with -DBUILD_STATIC_LIB=ON in cmake command.After this i was successfully able to generate solution files.But when i tried to build them i am getting below errors.

On the other hand i am successfully able to build the project with VS2019.
Using cmake command with curl and boost path without _G flag to get solution files.
and cmake --build . command to build project.
