- not fully tested

- additional cgal-headers-only rules (future use)

COMP: add -lgmp for CGAL with mpfr linkage

- adds into the include-quoted search list instead the general (-Idir)
  search list.

  * makes it less subject to ordering (since it will now generally be
    searched first) and makes it less subject to how duplicate removal
    is implemented. In some compilers (#1627), the last instance of
    a duplicate directory would be used and not the first instance.

  * removes clutter in some Make/options files

COMP: add missing linkage libraries

- improves build robustness, even with a reduced environment (#517)

ENH: improve cmake/ParaView config handling

See merge request !358

- improve handling of changes in ParaView/VTK or cmake parameters (#1693)

  * adjust internals to support recording of an unlimited number of
    configuration parameters and use file `cmp` instead of trying
    to check strings ourselves.

ENH: new wmake/scripts/wmake.cmake-args handler

- additional handling of -prefix=... as CMAKE_INSTALL_PREFIX export.

- in some contexts, can use instead of AllwmakeParseArguments

- faster and fewer issues with high aspect ratio cells.

- `blockMesh -merge-geometric` for old behaviour

- see commit 7da0b5be

- this specifically arises in the case we have used the `#eval` syntax
  to generate a value.
  However, since the expressions produce scalar/vector/tensor etc, the
  tokenized value will *not* be introduced into the dictionary as a
  label, even if it appears to be an integer value.

  Eg, eval "2*5", eval "sqrt(100)" both yield `scalar(100)`, which
  will not be suitable for any consumer expecting a label value.

  With the `#calc` version, this problem is glossed over since it uses a
  string buffer for the output (which can suppress the decimal)
  and re-parses the string into tokens, which causes a label to be
  recognized.

- Since we obviously already support implicit handling of ints as
  floats (when reading), now also allow conversion of float
  representations of integral values.

  Uses the ad hoc value of 1e-4 for deciding if the value deviates too
  far from being integral.

- As a side-effect, can now also support scientific notation when
  specifying integers.  Eg, (10 100 1e+3) for cell counts.

- were deprecated via comments (2018-10).
  Now mark with compilation warning

Update primitive patch templating and storage

See merge request Development/openfoam!357

- simplified templating, which cleans up code and does not appear to
  break any normal user coding.

ENH: unique_ptr instead of homegrown demand-driven handling.

- allows easier identification for future changes

WIP-ENH: add directionalMeshWave functionality

See merge request Development/openfoam!356

  For a given point within a given mesh, the existing `meshWave` method gives
  the orthogonal distance to a patch. In meshes with very steep terrain (e.g.
  a hill of 90 [deg], this might be problematic for the fields that require
  the distance to the patch associated with the terrain surface.

  `directionalMeshWave` is a variant of `meshWave` distance-to-patch method,
  which ignores the component in the specified direction. Can be used e.g. to
  calculate the distance in the z-direction only.

  TUT: add example of directionalMeshWave to mesh/moveDynamicMesh/SnakeCanyon

  Requirement by CENER
  Implementation by Mattijs Janssens

- preliminary to further changes (#1675)

- takes a search string and a replacement character.
  The replacement character can also be a nul char ('\0'), which
  simply removes the characters.

  Possible uses:

  * Replace reserved characters
      str.replaceAny("<>:", '_');

  * Remove shell meta-characters or reserved filesystem characters
      str.replaceAny("*?<>{}[]:", '\0');

- construct from dimensioned/value, defaulting name from value.
  Can be convenient for these type of operations:

      max(.., dimensionedScalar(somedims, 0.5))

- construct from dimensioned/one, forwarding to pTraits::one.
  Can be convenient for constructors:

    volScalarField( ..., dimensionedScalar(somedims, one{}))

ENH: minor updates to zero/one classes.

- add global 'One' constant for symmetry with 'Zero'.

- use dictionary::get<..> instead of lookup in a few more places

- an otherwise confusing amount of output that may not be expected

- clearer than passing a reference to a dummy variable,
  or relying on move occuring within the copy constructor
  (historical, but should be deprecated)

STYLE: consistent autoPtr syntax for uncollated file operations

- can help in circumstances when an zero-sized entry is written on
  some processors, but the compound-type may be useful for determining
  a particular code path when re-reading the files. Ensures that the
  information is consistent on all processors.

STYLE: adjust separation of includes between List.H and UList.H

Also adds pointTopoDistance, edgeTopoDistance.

- various changes

- bin/tools/create-mpi-config to query/write values for system openmpi.
  In some cases this can be used to avoid an mpicc requirement at runtime.

- adjust openfoam session to include -test-tutorial forwarding to the
  tutorials/AutoTest. This helps with writing installation tests.

- adjust foamConfigurePaths to latest version

- removal of gperftools default config, as per develop
