Setting up on arm Macs for the first time

I am setting up the SDK environment on vscode on Mac (arm architecture) and clang 15.0.0 and getting the error(s);
CMake:

• I am unsure why clang c++11 standard compiling(linking) in the aws headers appear to throw so many errors
• what should I correct to fix this setup?

Can you try turning off the warnings are errors cmake flag? You can do that by adding -DAWS_SDK_WARNINGS_ARE_ERRORS

[AbeOwlu]

thank you for the suggestion, @jmklix .
I turned off the AWS_SDK_WARNINGS_ARE_ERRORS parameter. The same errors thrown;

Can you try installing in the terminal and see if that works for you? Here Are the commands I use to build in the terminal:
cmake .. -DBUILD_ONLY="s3" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX="" -DENABLE_TESTING=OFF
cmake --build . --config=Debug
cmake --install . --config=Debug

cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_PREFIX_PATH=""
cmake --build ./ --config Debug
