  # NOTE: we use LCMS_ROOT as WEBP root since there is not other setting for webp.
  # NOTE: The Pillow install script will, by default, add paths like /usr/lib
  # and /usr/include to the search paths. This can break things when building
  # on a non-NixOS system that has some libraries installed that are not
  # installed in Nix (for example, Arch Linux has jpeg2000 but Nix doesn't
  # build Pillow with this support). We patch the `disable_platform_guessing`
  # setting here, instead of passing the `--disable-platform-guessing`
  # command-line option, since the command-line option doesn't work when we run
  # tests.
