Where can I set path to make.exe on Windows?

The path is in the registry but usually you edit through this interface:

1. Go to Control Panel -> System -> System settings -> Environment Variables.
2. Scroll down in system variables until you find PATH.
3. Click edit and change accordingly.
4. BE SURE to include a semicolon at the end of the previous as that is the delimiter, i.e. c:\path;c:\path2
5. Launch a new console for the settings to take effect.
