A user of HiGHS has observed that he is using "HiGHS v1.2.0 through SciPy in CVXPY".
The latest version of HiGHS is 1.7.2
For CVXPY to call HiGHS via SciPy was sensible in the past, since inter…

HiGHS uses the basis condition estimate in Hager84 . All that's required is five solves with each of B and B^T for a full RHS
The value is extracted using `Highs::getKappa` (see #1869)

## Summary
I'm unable to get the SCIP tests to pass when compiling SCIP with HiGHS set as the solver. Specifically I tested this with SCIP 9.1.0 and HiGHS 1.7.2 (and 1.7.1). It finished compiling w…
