can't install on macOs Monterey 12.1 (21C52) about py-webrtcvad

[Invisibility]

The reason is that clang doesn't allow -std=c++11 for C source file but -std=c++11 is needed for one C++ file in the extension.

I figured out one hack.

1. Comment out this line in setup.py: extra_compile_args.extend(['-std=libc++'])
2. Create the following shell script, chmod 755 the shell script and name it the same as your compiler (e.g. clang)

#!/bin/sh
echo wrapper called
if [[ "$@" == *"checks.cc"* ]]; then
   echo "c++ detected"
   /usr/bin/clang "$@" -std=c++11
else
   /usr/bin/clang "$@"
fi

3. change the $PATH (using export PATH=<path to shell script>:$PATH) so the shell script will be invoked first
4. run the install command
