Download http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt and place
it as Licenses/LGPLv2.1.txt in our source tree. When building cmake-gui,
use option CMake_GUI_DISTRIBUTE_WITH_Qt_LGPL to enable notification
in the "About" dialog of how the distribution of Qt is licensed.
Install the license file as ${CMAKE_ROOT}/Licenses/LGPLv2.1.txt so that
the dialog can display a path to it.
Since commit 7d47c693 (Drop compatibility with CMake < 2.4, 2013-10-08)
we no longer need to use the configure_file IMMEDIATE option to support
compatibility modes less than 2.0.
Configure our Sphinx conf.py with a copyright line extracted from
Copyright.txt instead of using the year in which the documentation is
built. This will future-proof the reported copyright year range when
building documentation for old versions.
Add the man page description line as explicit markup at the top of each
Help/manual/*.rst file and scan it from conf.py to automatically
generate the man_pages Sphinx configuration value. This reduces the
number of places that need to be changed when a new manual is added.
Include the CTestUseLaunchers module in the standalone build of
Utilities/Sphinx so that it can be built under CTest with the
CTEST_USE_LAUNCHERS option.
When scanning CMake module files for .rst comments, recognize
bracket comments starting in ".rst:" too. For example:
#[[.rst:
Include the bracket comment content terminated by the closing bracket.
Exclude the line containing the bracket if it starts in "#".
Teach the CMakeLib.testRST test to cover multiple bracket lengths
and ending brackets on lines with and without "#".
Update the cmake-developer.7 manual to document the bracket-comment
syntax for .rst documentation.
Generator expressions are supported in many places and are a distinct
concept worthy of their own manual page. The old builtin documentation
was previously represented by preprocessor macros to generate it into
each place that supports them. Factor out the duplicate content into a
dedicated cmake-generator-expressions manual page and reference it from
each original location.
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.
Drop the 'documentation' build target. We will no longer use the
executables to generate their own documentation. New infrastructure
will be introduced later to generate documentation.
The final location and name of a build-target is not determined
until generate-time. However, reading the LOCATION property from
a target is currently allowed at configure time. Apart from creating
possibly-erroneous results, this has an impact on the implementation
of cmake itself, and prevents some major cleanups from being made.
Disallow reading LOCATION from build-targets with a policy. Port some
existing uses of it in CMake itself to use the TARGET_FILE generator
expression.

CMake is aware of the policy's NEW behavior and the AppleClang compiler
id. Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.
Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.
Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang. Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.
Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.
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.
Avoid requiring CMake 2.8.6 for CMakePushCheckState or CMake 2.8.8 for
CMakeExpandImportedTargets. Drop the custom versions of CMake modules
CheckCSource(Compiles|Runs) because we do not use the SAFESEH option
anyway.
Follow up change from commit ffa6faa4 (libarchive: Include cm_zlib.h to
get zlib used by CMake, 2011-12-20) for new includes of zlib.h in
updated libarchive.
The archive_string_conv type sc variable already freed via free(sc) on
the other hand in second line we are tyring to free its subset via
free(sc->from_charset) this will cause a problem because we couldn't
reach sc after first release.

LLVM headers define strlcat as a macro rather than as a function.
See upstream Curl issue:
http://curl.haxx.se/bug/view.cgi?id=1192
It was addressed by removing use of strlcat altogether. Port the
upstream fix to CMake's curl.
caught by clang's -fsanitize=shift. A small unsigned int was
promoted, according to C's regular promotion rules, to a signed
int, it was then left shifted. This sometimes pushed a 1 into
the sign bit, which is undefined behaviour. Fixed by using
unsigned temporaries.
