The cmLinkImplItem class used to contain some additional members to support the CMP0027 policy. Since the CMP0027 policy and those associated members were removed, the cmLinkImplItem class has been a plain wrapper around cmLinkItem with no additional members. It is no longer needed and cmLinkItem can be used directly wherever cmLinkImplItem was used previously.
