    If not already set, use the latest installed version of the Windows 10 SDK.
    The Windows 10 SDK is backwards compatible to Windows 7, as long as WINVER and _WIN32_WINNT are set before compiling.
    Note:
      - With VS2019, VS2022 using a value of "10.0" means that it will use the latest installed version.
      - With VS2017, we need to manually detect the latest SDK version from the registry.
      - With VS2015, use the Windows 8.1 SDK.
