This is a non-trivial problem, two approaches doing this are implemented in open_karto and cartographer. For the latter, you can read about the clever branch-and-bound approach used in this paper.

In gmapping, there is no explicit detection of loop closures, but map hypotheses with "badly" matched parts get a low weight and get sampled out.
