SolarisStudio: Use alternative standard library to build CMake.
SolarisStudio ships a very old RogueWave standard library
implementation (libCstd) and uses it by default for backward compatibility.
The macros defined when building the system libCstd need to be the same as
the macros defined when using it for binary compatibility reasons etc. The
SolarisStudio compiler driver adds macros such as _RWSTD_NO_MEMBER_TEMPLATES and
_RWSTD_NO_CLASS_PARTIAL_SPEC etc. These macros disable certain APIs in the
standard library headers.
Although the compiler supports the features 'member templates' and 'partial
template specialization', the standard library does not provide APIs which
rely on those features. This means that std::vector::insert in libCStd does
not accept a pair of iterators from a different type of container, because
that requires member templates, and reverse_iterator<const T> can not
be constructed from a reverse_iterator<T> because that requires partial
specialization (or at least the _RWSTD_NO_CLASS_PARTIAL_SPEC define) and
member templates.
This causes many problems while building CMake using SolarisStudio, which
have not been well understood until now. The problems are usually
attributed to compiler limitations, while actually the problem is in
the standard library, as in commit v3.0.0-rc1~99^2~1 (Help: Document non-use
of std::set::insert., 2014-01-24) and commit 107dcac3 (Fix compilation with
the Oracle / Sun compiler (#15318), 2014-12-12).
SolarisStudio 12.3 and earlier also ships a version of stlport which may be
used instead of libCstd by specifying -library=stlport4
https://docs.oracle.com/cd/E18659_01/html/821-1383/bkakg.html
SolarisStudio 12.4 ships a version of libstdc++ from GCC 4.8.2 which may be
used by specifying -std=c++03 or -std=c++11 etc
http://docs.oracle.com/cd/E37069_01/html/E37075/bkamw.html#OSSCPgnaof
Use these more-capable standard library implementations when building cmake.
This will allow more use of 'normal' C++ (such as std::vector::insert), and cause
fewer surprises resulting from dashboards using SolarisStudio.
Because cmake is not a library linked against by 3rd parties and does not have
external dependencies, issues related to mixing code using libCStd and libstdc++
do not apply.
