Hi willcampo@hotmail.com,
You have to set APU_TOOLS and S32V234_SDK_ROOT as environment variables.
1. If you use Windows 10, open Start menu and type "Edit the system environment variables"

2. In the newly open "System Properties" window click on "Environment Variables" button.

3. Another window will open, named "Environment Variables". In this window you can add a new environment variable by pressing "New" button.

You can find the instructions for other versions of Windows operating system on https://www.computerhope.com/issues/ch000549.htm .
