`-DBEMAN_BIG_INT_BUILD_BENCHMARKS=ON`, or use a `*-release-benchmarks` preset);
the `*.perf.cpp` and `*.limbs.cpp` programs are standalone and depend on
Boost.Multiprecision and GMP, so they are compiled by hand.

The GMP gap analysis (where `big_int` is slower or faster than GMP, per operation and size band, with flame graphs
and a ranked optimization list) is in [`gmp_gap_analysis.md`](gmp_gap_analysis.md).
