The usual way to do this is to master the CD with deliberate errors in the
data stream or disc structure and to use a loader that detects and igores
those errors. However, this is beyond the scope of your average CD burning
utility and in any event there is no shortage of disc copying utilities that
can cope with these discs and pretty well any other scheme in use.
Most software distributors have abandoned protecting the CD itself and
instead gone for a system where the user has to obtain a licence key that is
specific to that user, and often the machine on which he is running it. The
only downside of this latter scheme is the software can potentially become
useless if the supplier goes out of business.
