CMake: fall back to OpenSSL on older OS X Starting at OS X 10.8, the Security framework offers some functions which are unified across OS X and iOS. These are the functions that we use. Older versions of OS X do not have these functions and we fail to compile. In these situations, fall back to using OpenSSL for our TLS stream instead.
