# 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.
