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

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

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.

CMAKE_SYSTEM_PROCESSOR is not guaranteed to be defined (per
http://www.cmake.org/Wiki/CMake_Cross_Compiling), and when cross
compiling where it happens to be undefined, this module was broken.

Case where CPACK_CMAKE_GENERATOR value is non existent or
or contains multiple words that were not quoted was not
handled and produced a segmentation fault.
AppleClang does not support the cxx_thread_local feature, even
though it is based on a Clang version which does support the
feature.
http://stackoverflow.com/a/23850891/2428389
A possible reason for that is that thread_local might be used as
a variable in existing Apple SDK headers.
Extend the WriteCompilerDetectionHeader module to generate a define
for that feature with portability fallbacks. For the avoidance of
making it easy to write code which looks correct but which has odd
runtime behavior, don't set the define symbol at all if no
equivalent keyword is known.
Expect tests to specify stderr content if it is present.
Fix the CMP0019 test, which has only been testing the WARN status
until now. Specify in the CommandLine and FPHSA tests that content
is at least one character.
Set policies in the Language and CheckModules tests, which have empty
test output, modulo unrelated policies on some platforms.
