- adios: 2.9.2 -> 2.10.1
- paraview: 5.11.2 -> 5.12.1

Ancillary libs:

- hdf5:  1.14.4.3
- hypre: 2.23.0 -> 2.31.0
- petsc: 3.19.2 -> 3.21.2

- ADIOS2-2.7.1      latest
- CGAL-4.14.3       latest without c++14 requirement
- ParaView-v5.10.0  final (or RC2)
- boost_1_74_0      newest is 1_77_0 but had problems with gcc-4.8.5

- when installed in-source, use PETSC_ARCH to find additional include
  directory and the correct library directory

CONFIG: bump to new hypre version

- add -hint option for have_adios2, have_hypre, have_petsc

- no stderr redirect needed:
    * 'command -v'

- no stdout/stderr redirect needed:
    * 'rm -f'

STYLE: consistent spacing after redirects

- foamCleanPath now only splits the environment variable on ':', which
  allows other directories with spaces or '(..)' etc to pass through
  without major issue.

- The filter arguments are split on whitespace, colons or semi-colons.

- ADIOS 1.13.0
- fftw 3.3.7
- paraview 5.4.1

ENH: include ThirdParty QT libraries in LD_LIBRARY_PATH for paraview

- handling of dead links (find -L -delete unsupported)

- remove ignore case flag on 's/../../i' used in have_scotch script.
  It is unneeded and not tolerated by Darwin's sed.

- avoid embedded comments in EXE_INC (Make/options files), which do
  not work well with the OSX LLVM cpp.
  It strips out the comments but also removes the continuation char.

STYLE: adjust notes about paraview library locations

- export library path for gmp/mpfr from CGAL config files.
  This is required when non-system gmp/mpfr libraries are being
  used, but not using a ThirdParty compiler installation.

- automatically handle lib/ vs lib64/ (eg, for central installations)
  for packages such as boost, CGAL, etc. While the ThirdParty
  compilation of these will normally land in lib64/, this may not be
  the case when they are supplied by another means.

- reworked the handling of foamEtcFile and foamCleanPath for less
  clutter in the configuration files.
  Added the bin/tools/lib-dir script to handle logic that is
  too complex to easily manage in csh.

- suppress error messages that appear with zsh.
  According to unset(1p), 'unset -f' unsets a function.
  If the function was not previously defined, this is a no-op.
  This is similar for zsh, but there it emits a warning if the
  function was not previously defined.

- avoid 'local' in functions sources from etc/bashrc.
  ksh does not support this.

- use 'command' shell builtin instead of 'type'.
  Seems to be more consistent between shell flavours.

- as per bashrc,cshrc delimit with
      "# USER EDITABLE PART"
      "# END OF (NORMAL) USER EDITABLE PART"

  this can help simplify any patching for system-building scripts etc.

* boost 1_62_0 (Sept 2016)

* CGAL 4.9 (Sept 2016)
  - now has headers-only mode that could be interesting

* FFTW 3.3.5 (Jul 2016)

* openmpi 1.10.4 (Sept 2016)
  - the first openmpi 2.x release is also available, but too early to switch

* paraview 5.2.0 (Nov 2016)
  - builds without additional patching

STYLE: removed unneeded CMake environment variables

- many systems may not have boost or FFTW installed, or in an older
  version. Using ThirdParty for them should lead to a more robust
  build process.

- replace with an alternative workaround.

  Unset the _foamAddLib function prior to sourcing config.sh/CGAL:

  - LD_LIBRARY_PATH will not be adjusted.
  - cgal_version/boost_version variables will be retained.

Note: for ThirdParty builds, it is important that the boost and CGAL
paths are added into LD_LIBRARY_PATH even if before they are created.
This ensures that the OpenFOAM environment is functional after the
build.

The '*-none' and '*-system' specifications can still be used to avoid
setting them at all.

- also update settings to include newer compiler versions

Patch contributed by Bruno Santos:
 - "etc/config.sh/CGAL":
   - Indented the contents of the recently added if block.
   - Added comment about using system versions.
   - Library paths are now only added if the respective version is not "boost-system" and "cgal-system".

 - "src/renumber/Allwmake":
   It now relies on the previous file to get the version for
   Boost (the same way as in "makeCGAL"). This is so that it will also
   build "SloanRenumber" if "boost_version" is set to "boost-system".

 - "applications/utilities/mesh/generation/Allwmake":
   It now also relies on the script "config.sh/CGAL" to get the
   version for CGAL. If "cgal_version" is set to "cgal-system", it
   will now also build "foamy*Mesh" utilities and respective
   libraries.

Resolves report http://www.openfoam.org/mantisbt/view.php?id=1232

 1. "foamCompiler" was changed to a more permanent "WM_COMPILER_TYPE"
    environment variable, so that it can be used by 3rd party
    installation scripts, such as "makeGcc", "makeLLVM" and so on. More
    on this will be provided in issue #1215.

 2. The script functions such as "_foamSource()" and "_foamAddPath()"
    were moved to a new file "etc/config.sh/functions". It has the
    ability to set or unset, depending on whether "WM_BASH_FUNCTIONS" is
    defined or not. This allows for these functions to be reused by
    other scripts, such as "makeGcc".

 3. The script "etc/config.sh/CGAL" relies on whether a local
    environment variable "SOURCE_CGAL_VERSIONS_ONLY" is defined or not,
    so that it will load only the version settings if it's defined. This
    is to make it easier to call this script from "makeCGAL". Although
    it still feels a bit of a clunky hack, but I didn't manage to deduce
    any other way we could do this :( I didn't add indentation within
    the if-block, to make it easier to read the changes. In addition,
    the local variable "common_path" is used to shorten the length of
    the lines and use slightly less repeated code.

 4. Added another new script "etc/config.sh/compiler", which has only
    the version numbers for the compilers taken out from the "settings"
    file. It currently depends on "WM_COMPILER_TYPE" for setting the
    variables, the same way it did with "foamCompiler". This script is
    now always sourced from the "settings" file, for the following
    reasons:

   - "makeGCC" and "makeLLVM" can now take advantage of this script file.

   - The example "compiler" script (detailed next) can rely on this
     script file and then override parameters on-demand, as well as
     allowing for system compilers to have dedicated settings, such as
     setting "WM_CC". This is similar to how the example environment
     script for "paraview" works.

 5. To the script "etc/config.sh/example/compiler" were added a few more examples:

   - It now starts with a block where it first loads the default "compiler" script.

   - Has a "WM_COMPILER=Gcc48u" case example for when we try to use GCC
     4.8 in Ubuntu 15.10. This is just to give the idea that in a
     particular system, we might have several system-wide compiler
     versions. For example, in Ubuntu 15.10, there is GCC 4.7, 4.8 and
     5.2, which could be used for testing performances or compatibility
     with some other 3rd party library.

   - Has the "WM_COMPILER=Icc" case example, related to the original bug
     report, where "WM_CC=icc" and "WM_CXX=icpc", so that the user then
     simply copies this file to their own local preferences folder.

 6. Small bug fix in "etc/config.sh/mpi", where unsetting "minBufferSize" was missing at the end of the script.

 7. Small change in "etc/config.sh/paraview", where "CMAKE_ROOT" is set
    along with "CMAKE_HOME". This is due to a rare issue that occurs on
    people's systems where they have a custom system-wide CMake version
    installed and which is used by having "CMAKE_ROOT" set on that
    environment. This can mess up OpenFOAM's custom ParaView builds,
    given that conflicting CMake versions can lead to not building
    ParaView at all.

   - For more details about "CMAKE_ROOT":
     https://cmake.org/Wiki/CMake_Useful_Variables [^]

 8. The scripts "_foamAddPath _foamAddLib _foamAddMan" were not being
    unset at the end of "settings". They are now unset at the end of
    "bashrc", through a call to the new double-use "functions" script.

Additionally all references to "foamCompiler" have been changed to
"WM_COMPILER_TYPE".

etc/config.sh and etc/config.csh

This structure is more convenient to add support for other shells, e.g. zsh, fish etc.

To compile with 64bit labels set

WM_LABEL_SIZE=64

in ~/OpenFOAM/dev/prefs.sh

source ~/.bashrc

then Allwmake in OpenFOAM-dev.

This will build into for example OpenFOAM-dev/platforms/linux64ClangDPInt64Opt

If WM_LABEL_SIZE is unset or set to 32:

WM_LABEL_SIZE=32

the build would be placed into OpenFOAM-dev/platforms/linux64ClangDPInt32Opt

Thus both 32bit and 64bit label builds can coexist without problem.

- use standard *.sh, *.csh endings
