- this solves some 'dangling' dependency problems that plagued earlier
  versions (when MS-MPI was not also installed).

COMP: update include for CGAL-5.5 (#2665)

  old:  Robust_circumcenter_filtered_traits_3
  new:  Robust_weighted_circumcenter_filtered_traits_3

COMP: adjust CGAL rule for OSX (#2664)

- since CGAL is now header-only, the previous OSX-specific rules have
  become redundant

- has a special purpose beginPiece() method, but was missing an update
  on the numberOfPoints, numberOfCells values required by the base class.

- old logic (v2206 and earlier) always disabled writing on non-master,
  but other parts of the code were more recently updated to use lazy
  evaluation of surface data (with parallel communication)

- now retain full write/no-write logic identically on all ranks. Take
  care of master/non-master at the final output stage.

- some regressions (especially with ptscotch) noted with scotch-7.0.1

- no guarantee that dpkg-architecture command is actually available,
  so revert to a reasonable guess from 'uname -m' and 'uname -s'

Misc. changes in finite-area methods

See merge request !585

Kutalmış Berçin authored Dec 02, 2022 and Mark OLESEN committed Dec 14, 2022

It has been observed that the finite-area framework is prone to numerical
issues when zero-valued edge lenghts, edge/face normals and face areas exist.

To improve exception handling at identified code sections to gracefully
overcome math errors, the problematic entities are lower-bounded by SMALL.
