Just ran into the same problem in https://trac.sagemath.org/ticket/25374#comment:115. The homebrew folks seem to have a workaround: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/cryptominisat.rb#L39

Do you also plan to add implementations of the tableau access functions (https://github.com/coin-or/Osi/blob/master/src/Osi/OsiSolverInterface.hpp#L1985)?

Do you have a pointer where I find these? My actual goal is to get a pivot-level interface in Python, preferably going through the Cython interface to HiGHS in scipy,...

Quick comment on highspy: Consider adding a `pyproject.toml` file to declare the build-time dependencies on pybind11 and pyomo

> A direct interface to HiGHS from Pyomo is in the pipeline Will a future Pyomo version include a vendored copy of HiGHS then (in source distribution and/or wheels)?

> The only reason to leverage the scipy-HiGHs interface (or really, that HiGHs is distributed as part of scipy) is that it could be the most straightforward way for Pyomo...

It's explained pretty well in the cited issue Homebrew/homebrew-core#68528 - care to look?

> the root cause is that CPython's global CFLAGS/LDFLAGS cannot be overridden by the ones provided by the package. Well, that's exactly why the `-I` and `-L` flags that you...

> Second, the fix proposed [...] deletes them from extension build flags altogether rather than lower their priority as intended `distutils`/`setuptools` have no mechanism for "lowering priority". The flags from...
