- Only reference the FOAM_EXT_LIBBIN locations when linking.
  The respective SCOTCH_ARCH_PATH/lib, METIS_ARCH_PATH/lib locations
  either do not exist, or are possibly inconsistent and won't be
  seen at run-time anyhow.

- Incorporate decompose/metisDecomp/Allwmake into the top-level
  decompose/Allwmake

On 64-bit systems, the system installations of boost, cgal are under
lib64/. The behaviour for a ThirdParty build is mostly lib/ but this
can also be changing.

    Boost 1_62_0 and older build into 'lib/'.
    CGAL-4.9 builds into 'lib64/', older versions into 'lib/'.

Future-proof things by using lib$WM_COMPILER_LIB_ARCH for boost and
cgal build rules, and forcing these as build targets in the ThirdParty
makeCGAL as well.

STYLE: check for boost/version.hpp, CGAL/version.h instead their directories

- was incorrectly writing it as "startFace", which would be
  immediately overwritten anyhow

STYLE: avoid noisy output when adding the boundary 'type' in mesh conversion.

Reworking of the ensight infrastructue and new ensightWrite function object

Provide common face area/normal support in PrimitivePatch

For polyPatch, both the faceAreas() and faceCentres() are masked by their subField equivalents.
Since there is no polyPatch method for magFaceAreas(), the PrimitivePatch method will be seen.

See merge request !74

- still needs to be applied and tested

- Write the individual contents, without a surrounding 'boundaryField'
  block. Similar to what dictionary::writeEntries() offers.
