[new release] ortools (2 packages) (9.15.0)

[tbrk]

Build and export Google OR-Tools models

• Project page: https://github.com/inria/ocaml-ortools

CHANGES:

Include the v9.15 Google OR-tools source and build together with the OCaml
interface. Rewrite the interface in C++ to avoid an unnecessary copy and
allow feasible solution observers.

lint says conf packages should always use the 'conf-' name prefix, the 'conf' flag, and the 'depext' field all together, but this package only has a non-empty 'depext' field, but I'm not sure that applies to this package. While the package does have external dependencies and also builds some other dependencies internally, these are just the unfortunate details necessary to provide a convenient OCaml interface to CP-SAT (part of Google's OR-Tools).

The opensuse problems can be fixed by correcting the paths in /usr/lib64/cmake/ZLIB/ZLIB-relwithdebinfo.cmake. I've emailed a maintainer of the zlib-ng-compat-devel package.

Some of the other builds fail with C++ compilation errors. Since these are for older distributions, I prefer not to investigate them at this time.

I've just made 3 pull requests (update conf-zlib, add conf-bzip2, add conf-eigen3) to shift these three external dependencies out of the ortools_solvers package.

I don't think it's worth adding conf-* virtual packages for the other required depexts.
