Building mongo-driver-cxx on Windows

Question

I'm trying to download externally the mongo-cxx-driver on Windows from the given github repositories, but unfortunately my knowledge of cmake is less to none. I found the next given script in one of the stackoverflow questions: Building mongo-cxx-driver using CMake ExternalProject_Add, but even when it seems to work, it doesn't work. It does make the given project but without the libraries. May someone help with creating those libraries through cmake, externally or internally after downloading the mongo-c-driver and the mongo-cxx-driver from the github repositories. If someone could go through the needed steps I'd be delighted. Also if boost could be removed from this equation, it would be good.

The CMakeLists.txt file:

cmake_minimum_required(VERSION 3.12)

set(CMAKE_CXX_STANDARD 11) 

project(Test)

option(${PROJECT_NAME}_SUPERBUILD "Build ${PROJECT_NAME} and the projects it depends on." ON)

if(${PROJECT_NAME}_SUPERBUILD)

    include(ExternalProject)

    set(common_cmake_cache_args
        -DCMAKE_CXX_COMPILER:PATH=${CMAKE_CXX_COMPILER}
    )
    if(NOT DEFINED CMAKE_CONFIGURATION_TYPES)
        list(APPEND common_cmake_cache_args
            -DCMAKE_BUILD_TYPE:STRING=${CMAKE_BUILD_TYPE}
        )
    endif()
