Brad King 86578eccf2 Simplify CMake per-source license notices
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing".  The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.

Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically.  Manually fix up shebang lines and trailing
newlines in a few files.  Manually update the notices in a few files that the
script does not handle.

Stephen Kelly 4c69ec6f12 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.

Chuck Atkins 04f442f755 Workaround for short jump tables on PA-RISC.
The PA-RISC architecture requires special options for GCC to prevent
linker errors when libraries reach a certain size and / or complexity.
See http://mraw.org/blog/2007/10/10/Linking_on_hppa and gcc
documentation on -mlong-calls.

Ben Boeckel 29c3edb87a Avoid if() quoted auto-dereference
When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly
dereference or quote the variable. We want if() to auto-dereference the
variable and not its value. Also replace MATCHES with STREQUAL where
equivalent.

Guy Martin 8f2c2ccb0b Improve ld flags for CMake itself on Linux/HPPA
Workaround binutils bug by only marking unique section starting by
".text._".

This adds the HPPA workaround improved in commit b22a0f15 (bootstrap:
improve ld flag for Linux/HPPA builds, 2014-01-14) not only to the
bootstrap, but also to the normal build.

Until someone finds out what needs to be fixed in binutils this allows anyone
to compile a working CMake even in debug mode.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
