- packages, but installs too many files
- face plugin is not built
- face plugin wants to download a file, see opencv_contrib-4.7.0/modules/face/CMakeLists.txt:

ocv_download(
    FILENAME face_landmark_model.dat
    HASH ${__file_hash}
    URL
      "${OPENCV_FACE_ALIGNMENT_URL}"
      "$ENV{OPENCV_FACE_ALIGNMENT_URL}"
      "https://raw.githubusercontent.com/opencv/opencv_3rdparty/${__commit_hash}/"
    DESTINATION_DIR "${CMAKE_BINARY_DIR}/${OPENCV_TEST_DATA_INSTALL_PATH}/cv/face/"
    ID "data"
    RELATIVE_URL
    STATUS res
)
