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 399e9c46d8 Drop builtin property documentation
Drop all DefineProperty calls for non-chained properties.  Drop the
documentation from the chained ones.  The documentation for all
properties is now in Help/prop_*/*.rst files.

Brad King 80a3273b5e Drop all documentation formatters except Usage
We now need only the Usage formatter to support command-line options
that print basic usage, and the supporting indented=>preformatted markup
processor to support CMake message formatting.  Drop all other
documentation formatters and move the remaining code up into the top
cmDocumentationFormatter class.

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.

Brad King df62f64db7 Clean up install rules of CMake itself (#14371)
Ensure CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR are always
relative paths in CMake code, and set defaults accordingly.  Use the
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.

Brad King bf5a5bc8b4 bootstrap: Do not suppress CMAKE_OSX_SYSROOT if CFLAGS have -isysroot (#14324)
Revert commit a1c032b9 (bootstrap: Suppress CMAKE_OSX_SYSROOT if CFLAGS
have -isysroot, 2012-09-21).  If MACOSX_DEPLOYMENT_TARGET is set then
CMAKE_OSX_DEPLOYMENT_TARGET will be set and Darwin.cmake will complain
if no CMAKE_OSX_SYSROOT is set.  Just allow both -isysroot flags to
appear.  The one generated by CMAKE_OSX_SYSROOT appears after and
overrides the one from CFLAGS/CXXFLAGS.

Brad King a1c032b994 bootstrap: Suppress CMAKE_OSX_SYSROOT if CFLAGS have -isysroot
In order to bootstrap on OS X with Xcode without the command line tools
one must add -isysroot to CFLAGS and CXXFLAGS.  In this case the flags
will make it into the configured CMake.  Set CMAKE_OSX_SYSROOT to empty
in the initial cache to prevent CMake from adding -isysroot again.

Stephen Kelly f1eacf0e07 cmGeneratorExpression: Re-write for multi-stage evaluation
The expressions may be parsed and then cached and evaluated multiple
times.  They are evaluated lazily so that literals such as ',' can be
treated as universal parameter separators, and can be processed from
results without appearing literally, and without interfering with the
parsing/evaluation of the entire expression.

Brad King 7195aca54f Make platform information files specific to the CMake version
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use.  The
method of detection and the exact results store varies across CMake
versions as things improve.  This leads to problems when loading files
configured by a different version of CMake.  Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files.  This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).

Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version.  Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake.  Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.

Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose.  The new variable points
at the version-specific directory while the old variable did not.

Brad King e5dc76894a bootstrap: Port back to old shells (#13199)
Since commit f39e82c9 (bootstrap: Re-implement command line option
processing, 2011-12-16) bootstrap uses POSIX shell expressions of the
form "${x#y}" to remove prefix pattern 'y' from the vaule of 'x'.
Although this is allowed by POSIX old shells on some platforms do not
support it.  Revert to using 'sed' to work with old shells.

Brad King e48796b26b KWSys: Fix SystemTools environment memory handling (#13156)
The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory.  However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv.  If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.

Replace use of putenv with setenv/unsetenv when available.  The latter
manage internal copies of the values passed instead of referencing the
original memory.  When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory.  This requires an "unputenv" implementation.  On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms.  On other platforms fall back to direct
manipulation of "environ".

Also add UnPutEnv to the API and add a test for the behavior of both.

script to extract the version components from their new location.

Brad King 11d9b21126 Add cmGeneratorTarget to represent a target during generation
Some per-target information and logic is common to all generators.
Some of that information is currently stored in cmTarget but that
should be reserved for the configure step.  Create a class to hold
per-target information for generators.  On construction classify
sources from the target and store them in separate members.  This
classification is already implemented separately in each generator.

Brad King 5cd879c4e7 bootstrap: Convert MSYS paths to Windows format (#13001)
We set CMAKE_PREFIX_PATH from the --prefix= option.  The calling shell
might not translate "/c/..." to "c:/..." paths but we need to store
Windows paths in CMake cache variables.  Pass the specified path through
the MSYS shell in a form it will convert to a Windows path using the
MSYS fstab.

Some MSYS bash implementations leave trailing space on the command line
to 'cmd /c echo ...' after quoting the message.  The Windows echo tool
preserves both the quotes and the trailing space.  Use a sed expression
that strips quotes and trailing spaces after the end quote.
