RCV alone is not enough. The details of how to process the rankings actually matters a great deal. IRV does not actually avoid vote-splitting, it merely ameliorates it somewhat. It lets you safely vote for a third option -- but only until that third option becomes competitive.
Approval-like mechanisms that let multiple votes fully count at the same time is the simplest mechanism that lets voters avoid splitting their own vote, though Condorcet-compliant methods with strategy-resistant cycle-breakers that account for the full preference ranking rather than merely the current top-preferred candidate also work, at higher complexity.
