Builds libscip (SCIP 10.0.2 + SoPlex 8.0.2 + Ipopt 3.14.19 + MUMPS 5.8.2) from source with scipoptsuite-deploy v0.12.0's linux.bash recipe in place of the prebuilt libscip-linux*.zip upstream downloads, which has no riscv64 build.

All four interpreter builds failed while cythonizing scip.pyx: src/pyscipopt/matrix.pxi:236:4: 'axis' redeclared PySCIPOpt 6.2.1 requires an unpinned "cython >=0.21", so the isolated build pulls Cython 3.3.0, which rejects the annotated re-assignment of the `axis` parameter. Backport upstream's fix (scipopt/PySCIPOpt#1248, ca6631b) as a patch applied before cibuildwheel. The same log also shows setup.py picking /project/scip/lib64: the before-all moves the libraries into lib/ but left an empty lib64/ behind, and setup.py prefers lib64 when it exists, so the link would fail next. Move only lib/, include/ and bin/ into the project, matching what upstream's libscip-linux.zip contains.

License: Wheel bundles libscip with SCIP, SoPlex, Ipopt (EPL-2.0), MUMPS (CeCILL-C), METIS, LAPACK, nauty, dejavu, CppAD (EPL-1.0), AMPL/MP and tinycthread, plus libgfortran (GPL-3.0 with runtime exception); upstream ships no licence text for them, so the build adds it.
