          newPath = pathToDll + ';' + currentWindowsPath
          os.putenv('PATH', newPath)
docs: When the path to the DLL is not in Windows search path, Windows will not be
      able to find other DLLs on the same directory, so we have to add it to the
      path. This function takes care of it.
