OS X build and warning fix
Review Request #125800 - Created Oct. 26, 2015 and submitted
The cmake find file was missing, but CoreFoundation being a system framework, no need to search for it. OS X: Update code to not use deprecated functions/data structure CSSM_DATA and SecCertificateGetData have been deprecated since 10.7. This patch uses SecCertificateCopyData which is the official replacement.
Build on OS X 10.8
