matlab mex compile error with Xcode 4.3 or higher

http://www.mathworks.co.kr/support/solutions/en/data/1-FR6LXJ/

This is happening because the SDKROOT directory for Xcode 4.2 and earlier are:
/Developer/SDKs/MacOSX10.7.sdk/
but Apple changed this directory to
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/


이래서 안된다고 한다.
