- use "-pvMAJ.MIN" suffix for similarity with the paraview convention
- use sentinel file to ensure clean change of intermediate targets
- ensure all library files are being properly removed
- support gperftools-none, gperftools-system configurations
as per other third-party packages.
STYLE: clean up more environment variables
CONFIG: testing adios rule
- these directories are sometimes used for a central, non-thirdparty, non-system
installation
- leave gmp and mpfr as is, since it is not clear how these would interact with system
versions
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
- CGAL itself includes its library dependencies, we only need to
provide the -L... option to the proper ThirdParty locations.
Should help improve general build robustness.
The change from C++0x to C++11 allows all of C++11 functionality to be
used in OpenFOAM, in particular constructor delegation which avoids code
duplication or constructor helper functions. However, this also means a
change to the minimum gcc version supported which is now 4.7 rather than
4.5.
Note that gcc-4.7 does not support the entire C++11 standard but does
support all of the functionality currently needed for further OpenFOAM
development. The minimum gcc-version which supports the entire C++11
standard is 4.8 which is now the recommended minimum gcc version.
The pre-processor macro 'OPENFOAM_PLUS' is defined with a numerical
value equal to the currently compatible version number.
This can be used judiciously within user coding to help with minor
differences between OpenFOAM versions. For example,
#ifdef OPENFOAM_PLUS
#if (OPENFOAM_PLUS >= 1612)
...
#endif
#endif
or simply
#if (OPENFOAM_PLUS >= 1612)
...
#endif
which may be optionally overridden by version-specific rules.
For example the default rules for gcc on GNU/Linux x86_64 are in the
wmake/rules/linux64Gcc directory. If there is a need to change any of
the rules for a specific version of gcc, e.g. gcc-4.8.4 the directory
wmake/rules/linux64Gcc48 may be created into which any of the language
files may be provided containing the rules to override the defaults.
This resolves a whole range of issues and work-arounds with earlier
releases. This version of icpc is more or less compatible with the
latest gcc and clang compilers and only required one hack to avoid
warnings from PackedBoolList.H.
