 CMake Deprecation Warning at cmake/Tests.cmake:33 (CMAKE_POLICY):
  The OLD behavior for policy CMP0037 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

 #                                                                             #
 # Origin:
 #     This fish package was called with the attribute
 #     "useOperatingSystemEtc = true;".
 #
 # Purpose:
 #     Fish ordinarily sources /etc/fish/config.fish as
 #        $__fish_sysconfdir/config.fish,
 #     and $__fish_sysconfdir is defined at compile-time, baked into the C++
 #     component of fish. By default, it is set to "/etc/fish". When building
 #     through Nix, $__fish_sysconfdir gets set to $out/etc/fish. Here we may
 #     have included a custom $out/etc/config.fish in the fish package,
 #     as specified, but according to the value of useOperatingSystemEtc, we
 #     may want to further source the real "/etc/fish/config.fish" file.
 #
 #     When this option is enabled, this segment should appear the very end of
 #     "$out/etc/config.fish". This is to emulate the behavior of fish itself
 #     with respect to /etc/fish/config.fish and ~/.config/fish/config.fish:
 #     source both, but source the more global configuration files earlier
 #     than the more local ones, so that more local configurations inherit
 #     from but override the more global locations.

 if test -f /etc/fish/config.fish

  # We ensure that __extra_* variables are read in $__fish_datadir/config.fish
  # with a preference for user-configured data by making sure the package-specific
  # data comes last. Files are loaded/sourced in encounter order, duplicate
  # basenames get skipped, so we assure this by prepending Nix profile paths
  # (ordered in reverse of the $NIX_PROFILE variable)
  #
  # Note that at this point in evaluation, there is nothing whatsoever on the
  # fish_function_path. That means we don't have most fish builtins, e.g., `eval`.


  # additional profiles are expected in order of precedence, which means the reverse of the
