Describe the bug
When there are multiple Xcode.app installed on the local machine and the Xcode SDK path is changed using xcode-select, for example:

xcode-select -s /Applications/Xcode16.app/Contents/Developer
# Xcode SDK path
/Applications/Xcode16.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk

If the SYSROOT environment variable is not specified locally, it will cause compilation errors.

fatal error: 'TargetConditionals.h' file not found

To ensure compatibility with these scenarios, it is recommended to specify the -isysroot flag for clang. Chromium has also made similar adjustments in build/config/mac/BUILD.gn.
