Apple renamed CGColorSpaceCopyICCProfile to CGColorSpaceCopyICCData in 10.13. If you compile code with a minimum OS required of 10.13 or newer, [-Werror,-Wdeprecated-declarations] will cause an error to occur on use of the function with the old name. Add a compile switch so that no error is emitted regardless of the deployment configuration.
