Hi,
Hopefully this will help:
1) "Program "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64\cl" not found in PATH"
This indicates that the development environment is probably not setup. If you are going to use Visual Studio you may wish to look at this thread:

If you are just starting out with C++, I would recommend starting with the setup instructions described here:

My guess is that the rest of the errors you are seeing are related to include paths that need to be set for the WPILIB include directories.
I'm at my day job right now, but I can add more detail when I get home this evening. Hopefully the information I gave you above can help get you started.
