The approach in commit v3.1.0-rc1~1^2 (Xcode: Fix compiler id detection
when code signing is required, 2014-10-22) still requires a code signing
key when targeting a real device. Instead set CODE_SIGNING_REQUIRED to
"NO" to tell Xcode not to sign at all. Drop the corresponding setting
of the code signing identity.
The "." in the extension was dropped by commit v3.1.0-rc1~556^2~2
(cmSourceFile: Cache the isUiFile check, 2014-02-08) by mistake. This
caused the options to not be set.
Since commit v2.8.8~173^2 (FindRuby: clean up querying variables from
Ruby, 2012-02-17) we query RbConfig::CONFIG first and, if the command
fails or its output equates to a false constant, then fall back to
querying Config::CONFIG.
Due to the above, an error condition exists with Ruby 2.2.0; when
querying RbConfig::CONFIG['TEENY'], the output of '0' will be discarded
since it matches the false constant '0'.
In previous versions this wasn't a problem, but Ruby 2.2 has completely
removed Config::CONFIG. This causes RUBY_VERSION_PATCH to be set to an
empty string and the Ruby version to be detected as '2.2.' (instead of
'2.2.0').
Fix the output check to explicitly look for an empty string before using
the fallback query method. (Someone more familiar with Ruby might be
able to deem the fallback as unnecessary and fully remove it.)

f73718c9 Features: Enable writing of MSVC compiler feature header.
64c30bdc Features: Record for MSVC C++ 2015 and MSVC C 2010-2015.

3e34e833 Features: Test feature propagation with more-common features.
b3e86f4e Features: Test an expectation of whether OVERRIDE_CONTROL is expected
Notes:
VS2015 and above are the only MSVC versions to support cxx_final, so remove
usages from the tests, and instead only test for cxx_override.
VS2012 and above to conform to cxx_decltype_incomplete_return_types
proposal, but without support for auto return types the dcl.type.simple
example in the proposal doesn't compile.
VS2013 and above to conform to the updated cxx_contextual_conversions proposal,
but VS2010 and above pass the test.
Compilers such as MSVC have no explicit flags to enable C++11 mode,
it just is always on. So only run the link tests with compilers that require
a flag to specify the language version.
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.
Initializer lists are only properly supported in 2015 and above.
Previous Visual Studio releases said they supported initializer lists
but silently produced bad code.
Previously we expanded HAVE_FINAL to determine what the copied_file number
would be, but when we don't have cxx_final than HAVE_FINAL is not defined.
What we really want is to use expected_result.
