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.

Since commit v3.0.0-rc1~374^2 (Refactor internal resource location APIs

to refer to the "ctest" and "cpack" executables in the location where
they will be built after "make".

Brad King 7cbab17871 Change version scheme to use only two components for feature levels
Historically CMake used three version components for the feature level.
We released new features while incrementing only the third version
component.  Since commit v2.8.2~105^2~4 (New version scheme to support
branchy workflow, 2010-04-23) we used the fourth version component for
bug-fix releases and the development date:

 <major>.<minor>.<patch>[.<tweak>][-rc<n>] = Release
 <major>.<minor>.<patch>.<date>[-<id>]     = Development

This solidified use of three components for the feature level, and was
necessary to continue releasing 2.x versions because:

* Some existing projects performed floating-point comparisons of
  ${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION} to 2.x numbers
  so ``x`` could never be higher than 9.

* Version 2.9.<date> was used briefly in post-2.8.0 development in
  CVS prior to the transition to Git, so using it in releases may
  have caused confusion.

Now that we are moving to 3.x versions, these two restrictions go away.
Therefore we now change to use only two components for the feature
level and use the scheme:

 <major>.<minor>.<patch>[-rc<n>] = Release
 <major>.<minor>.<date>[-<id>]   = Development

Brad King 1093deebd0 Shorten CMake version used in install destinations
Since commit c9a5f34b (Cleanup use of CMake version in install
destinations, 2013-09-26) we use the full CMake version in default
install destinations.  For rapidly changing versions of the form

 <major>.<minor>.<patch>.<date>-g<commit>[-dirty]

used by developers this is too granular.  Instead use just

 <major>.<minor>.<patch>

as the version for default install destinations.  This will still
be granular enough for unique directories in releases.

On Cygwin continue to use the full ${CMake_VERSION} as was the case
prior to the above-mentioned commit.

Brad King bfe07aa97e Build Help documentation during CMake build using Sphinx
Add a Utilities/Sphinx directory to hold CMake build code to run the
Sphinx (sphinx-doc.org) documentation generation tool.  Create a
CMakeLists.txt file there capable of building either as a subdirectory
of the main CMake build, or as a standalone documentation build.

Add cache options SPHINX_MAN and SPHINX_HTML to select output formats
and SPHINX_EXECUTABLE to specify the sphinx-build executable.  Add
bootstrap options --sphix-man and --sphinx-html to select output formats
and --sphinx-build=<sb> to specify the sphinx-build executable.

Create a "conf.py.in" file to configure_file into "conf.py" to tell
sphinx-build how to build our documents.  Create a "cmake.py" Sphinx
extension module defining:

* The "cmake-module" directive used in Help/module/*.rst files to
  scan .rst markup from the corresponding Modules/*.cmake file.

* A Sphinx domain called "cmake" defining documentation object types
  for CMake Help/<type> directories: command, generator, manual,
  module, policy, prop_*, and variable.  Add a "role" for each type
  to perform cross-references.  Teach the roles to treat "<XYZ>"
  as placeholders instead of explicit targets if not preceded by
  a space.  Add cmake domain directives to define command and
  variable objects explicitly in .rst file content.  This will
  allow modules to define their own commands and variables and
  have them indexed and linkable.

* A Sphinx document transform that converts Help/<type>/*.rst documents
  into cmake domain objects of the corresponding <type> and adds index
  entries for them.  This will automatically index all CMake documentation
  objects and provide cross-reference targets for them with no special
  markup in the .rst files.

Brad King c9a5f34bd7 Cleanup use of CMake version in install destinations
Factor the CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR selection
out of CMakeLists.txt and into a Source/CMakeInstallDestinations.cmake
script.  Load the script from the original location of the code.

Cache the destination values as empty strings so we know if the user
sets them explicitly.  If not, then compute defaults based on the
platform and full CMake version string.  By not caching the versioned
defaults, we can change them in a single build tree as the version
changes.

Remove duplication of the install destination defaults from the
bootstrap script.  Cache empty defaults there too.  Parse from the CMake
code the default values to report in the help output.  Keep the CMake
code in a structured format to make this reliable.

Brad King c04995b46e cmake: Split -E command implementation into separate source file
Move the cmake::ExecuteCMakeCommand static method and all the static
methods it calls out of the 'cmake' class to a separate 'cmcmd' class.
Build the latter as part of the main cmake executable with cmakemain.cxx
and not in CMakeLib.  Drop unused header includes from "cmake.cxx".

By moving this implementation out of cmake.cxx we avoid carrying it
around in all the executables that use class 'cmake'.  It is needed only
for the main "cmake -E" functionality.

Rolf Eike Beer ca63bb1001 bootstrap: try better workaround for builds on Linux/HPPA
The workaround currently present works fine without -O or with -O1, but fails
with -Os or -O2 and higher. Using -O2 is common e.g. in Gentoo, as resulting in
bugs like this:

https://bugs.gentoo.org/473276

Prevent the workaround for higher optimization levels to make bootstrapping
more likely to succeed.

This is still a workaround as ld still keeps crashing in some situations.

Ensure CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR are always

install() command instead of install_files() and install_targets().
This is more modern and also avoids stripping of the first character
from user-specified destinations.

While at it, fix the default destinations reported in the bootstrap
help.
