Reduce dependencies of M2

[mahrud]

Currently:

==> Dependencies
Build: autoconf ✔, automake ✔, bison ✔, cmake ✔, libtool ✔, ninja ✔, pkg-config ✔
Required: bdw-gc ✔, boost ✔, eigen ✔, factory@4.1.3 ✔, fflas-ffpack ✔, flint@2.6.3 ✔, frobby ✔, gdbm ✔, givaro ✔, glpk ✔, gmp ✔, libatomic_ops ✔, libxml2 ✔, mathic ✔, mathicgb ✔, memtailor ✔, mpfr ✔, mpsolve ✔, ntl ✔, openblas@0.3.13 ✔, readline ✔
Recommended: cddlib@0.94k ✔, cohomcalg ✔, csdp ✔, fourtitwo ✔, gfan ✔, lrs ✔, nauty ✔, normaliz ✔, topcom ✔
Optional: tbb ✘

Some can become build dependencies, like eigen and fflas-ffpack, some like cddlib can be entirely removed. It might be good to statically link larger dependencies (like boost, openblas) and make them build dependencies.

ps: tbb is optional because it introduced a dependency on gcc, which caused some issues. Would be good to make it a recommended build dependency for both M2 and mathicgb again.

[mahrud]

Based on the current dependency tree, the dependencies with the most number of dependencies are: openblas, libxml2, tbb, boost.

That's a cool graph!

Any chance to use some bits from a brew-installed Singular?

[slel]

The boost issue that lead to pinning boost to 1.76 is now closed:

• Boost@1.78.0 missing stacktrace (and fiber?) libraries Homebrew/homebrew-core#95520

Does this mean boost can be unpinned here now?

If you can figure out how to made dependencies conditional on what bottles are installed that would be nice. Otherwise, it's pretty safe to just ignore brew's warnings that some factory or singular files are getting replaced ..

Sure, though I'm not particularly in a rush.
