Where:
  -l selects the Linux (l) host environment.
  -m selects the macOS (m) host environment.
  -c selects the Windows host and Cygwin (c) environment.
  -u selects the Windows host and Ubuntu under Windows 10 (u) environment.

  Default: Use host setup in the defconfig file
  Default Windows: Cygwin
