Describe the problem: I am trying to build a dylib of mediapipe for external use on MacOS platform. I am trying to build the framework and a cpu calculator from tensorflow, you can see my BUILD snippet below

load("@build_bazel_rules_apple//apple:macos.bzl", "macos_dylib")
macos_dylib (
  name = "mediapipe_framework.dylib",
    minimum_os_version = "10.3",
  deps = [
     ":mediapipe_framework",
     "@macos_opencv//:opencv",
  ],
)

cc_library(
    name = "mediapipe_framework",
    linkopts = select({
        "//conditions:default": [],
    }),
    visibility = ["//visibility:public"],
    deps = [
        "//mediapipe/framework:calculator_framework",
        "//mediapipe/framework/tool:calculator_graph_template_cc_proto",
        "//mediapipe/framework/port:logging",
        "//mediapipe/framework/formats:classification_cc_proto",
        "//mediapipe/framework/formats:landmark_cc_proto",
        "//mediapipe/framework/formats:detection_cc_proto",
        "//mediapipe/framework/formats:rect_cc_proto",

    ]  + select({
        "//conditions:default": [
            "//mediapipe/graphs/hand_tracking:mobile_calculators",
           "//mediapipe/graphs/object_detection:mobile_calculators",
        ],
    
        "//mediapipe/gpu:disable_gpu": [
            "//mediapipe/graphs/hand_tracking:desktop_tflite_calculators",
            "//mediapipe/graphs/object_detection:desktop_tflite_calculators",
        ],
    }),
    alwayslink = 1,
)

I am not sure why it doesnt work but then i get a message on top of tree master when building

I have also tried https://github.com/tensorflow/tensorflow/issues/41039 to change the darwin value. Sometimes if i modify the cpuinfo bazel file I get errors to XNNPack not having dependencies on line 4278.

/private/var/tmp/_bazel_me/b39a9c2497bafb052e53d56396554a9a/external/XNNPACK/BUILD.bazel:4278:26: Configurable attribute "deps" doesn't match this configuration (would a default condition help?).

I believe it has something to do with XNNPack. I dont think I need XNNPack (or is it even supported?) on MacOS. This might be an issue with TensorFlow trying to build MacOS with XNNPack.

I also tried to change the macos_dylib to cc_binary to build a “.dylib” and it builts but I cannot test it because I built with a newer version of MacOS and I get linking issues related to using this library built with the newest version of MacOS (not even sure it works anyways) because I cannot set the minimum macos version unless I use macos_dylib or even apple_binary.

Any reason why this doesn’t work?

**[Provide the exact sequence of commands / steps that you executed before running into the problem]

1. Clone mediapipe
2. Create an external folder in the root after mediapipe
3. Add the BUILD file with above build settings
4. Run command bazel build -c opt --define MEDIAPIPE_DISABLE_GPU=1 --copt -fvisibility=hidden --linkopt -s --strip always --cxxopt=-std=c++17 --apple_platform_type=macos mediapipe/external:mediapipe_framework.dylib
