Ajouter le support de webp à libtiff pour MacOS

Par défaut, homebrew installe la libtiff sans le support de webp. Voilà comment y remédier:

brew install webp
brew install libtiff
brew edit libtiff

Ajoutez depends_on "webp" et remplacez --disable-webp par --enable-webp :

class Libtiff < Formula
  desc "TIFF library and utilities"
  homepage "https://libtiff.gitlab.io/libtiff/"
  url "https://download.osgeo.org/libtiff/tiff-4.7.0.tar.gz"

  livecheck do

  end

  depends_on "jpeg-turbo"
  depends_on "xz"
  depends_on "zstd"
  depends_on "webp"
  uses_from_macos "zlib"

  def install
    args = %W[
      --prefix=#{prefix}
      --disable-dependency-tracking
      --enable-webp
      --enable-zstd
      --enable-lzma
      --with-jpeg-include-dir=#{Formula["jpeg-turbo"].opt_include}

      --without-x
    ]
    system "./configure", *args
    system "make", "install"
  end

  test do
    (testpath/"test.c").write <<~C
      #include <tiffio.h>

      int main(int argc, char* argv[])
      {
        TIFF *out = TIFFOpen(argv[1], "w");
        TIFFSetField(out, TIFFTAG_IMAGEWIDTH, (uint32) 10);
        TIFFClose(out);
        return 0;
      }
    C
    system ENV.cc, "test.c", "-L#{lib}", "-ltiff", "-o", "test"
    system "./test", "test.tif"
    assert_match(/ImageWidth.*10/, shell_output("#{bin}/tiffdump test.tif"))
  end
end

Puis recompilez:

HOMEBREW_NO_INSTALL_FROM_API=1 brew reinstall --build-from-source libtiff
