    target_os="ios"
    target_cpu="arm64"
    skia_use_metal=true
    skia_use_expat=false
    skia_enable_pdf=false
    EOM

    tools/git-sync-deps
    bin/gn gen out/ios_arm64_mtl

    target_os="ios"
    skia_enable_gpu=false
    skia_enable_pdf=false
    skia_use_expat=false
    EOM

    tools/git-sync-deps
    bin/gn gen out/ios_arm64_cpu
    ninja -C out/ios_arm64_cpu skottie_example

Then install the `out/ios_arm64_cpu/skottie_example.app` bundle.

## OpenGL
