c++ – Webrtc link issue under macOS

My compilation parameters

is_debug = true
target_os = "mac"
target_cpu = "arm64"
is_clang = true
treat_warnings_as_errors = false
rtc_include_tests = false
rtc_use_h264 = true
is_component_build = false
use_custom_libcxx = false
rtc_enable_protobuf = false
use_rtti = true
proprietary_codecs = true
ffmpeg_branding = "Chrome"
use_custom_libcxx_for_host = false

In my project:/Applications/Xcode. app/Content/Developer/Platforms/MacOSX. platform/Developer/SDK/MacOSX14.0. sdk/usr/lib/libc++. tbd. I should have linked to libc++, why is it still wrong.

There are also static libraries available

I have been troubled for several days and have been experiencing link errors. My version branch is m119
