Cannot build source

[Jsparham777]

Hi,

I am trying to build the solution but cannot get the AxoCover.Native.vcx project to build.
When I clone the repository, Visual Studio 2019 prompts me to re-target the Native project to the following:

• Windows SDK Version: 10.0 (latest installed version)
• Platform Toolset: Upgrade to v142

I accept this change and set the configuration to x64.
When I build the solution, the following errors are displayed:

What am I doing wrong?
