Error while building from source

[g7i]

I'm getting the following error while building from source on Mac M2

../../download/src/rtc_base/async_resolver.cc:60:3: error: 'dispatch_queue_global_t' is only available on macOS 10.14 or newer [-Werror,-Wunguarded-availability-new]

It seems like libwebrtc is being built with the wrong MacOS SDK. I haven't found a great way to configure it, so I just make my SDKs directory look like this:

> ls -la /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
lrwxr-xr-x - root 12 Jun 14:14 MacOSX11.3.sdk -> /Users/jackduvall/macos-sdk/MacOSX11.3.sdk
drwxr-xr-x - root 12 Jun 14:13 MacOSX14.5.sdk
lrwxr-xr-x - root 12 Jun 14:13 MacOSX14.sdk -> MacOSX14.5.sdk

Might interfere if you have other XCode projects tho, sorry about the weird build process...
