Fix issues #9959 and #9898 - do not set CMAKE_OSX_DEPLOYMENT_TARGET if CMAKE_OSX_SYSROOT is set. 

Default to "" for CMAKE_OSX_DEPLOYMENT_TARGET if CMAKE_OSX_SYSROOT is set. Also, add new error message to detect the case where there is a deployment target, but no SDK has been set. Fix args to STRING REGEX call so that it works even if _sdk_path variable is empty inside sanity check function.
