Teach set_property and get_property an "INSTALL" property type to be
associated with install-tree file paths. Make the properties available
to CPack for use during packaging. Add a "prop_inst" Sphinx domain
object type for documentation of such properties.
Use the CPack DragNDrop generator instead of the deprecated PackageMaker
tool to package CMake itself. This provides an installation experience
that is more consistent with other products on OS X and allows users to
select the destination directory easily. It also avoids installing
"/private/var/db/receipts/com.Kitware.CMake.*" receipts that must be
removed by "pkgutil --forget com.Kitware.CMake" before another version
of CMake can be installed.
The DragNDrop installer does not support a post-flight script, so drop
our configuration of it. The cmake-gui has an option for installing
symbolic links to enable command-line use. In practice users may simply
add "/Applications/CMake.app/Contents/bin" to their PATH instead.
In the domain clear_doc method, avoid removing entries from a dictionary
while iterating over it. Instead accumulate a set of entries to remove
at the end.

However, the return type from archive_entry_mode may be a signed integer
so the shift may overflow. Since the second argument of archive_le32enc
expects uint32_t anyway, simply cast to that prior to shifting.

Assistant in Qt 4.8 does not handle css import paths relative to
the includer. This is fixed in Qt 4.8 commit b95750a275 (Assistant: Set
the url on created QNetworkReply objects., 2014-03-31). It is unknown
whether there will be a further Qt 4.8 release containing that commit.
Use a CMake script to pre-replace the content prior to generating the
qch file. An alternative workaround of moving the files or adding
"_static" to the import path did not seem to work for existing Qt 4.8
versions.
The bug was fixed in the Qt 5 branch before Qt 5.0. The Qt 5 assistant
renders this workaround'ed version correctly too.
In some cases, it was possible for the include directory of the system-wide
libcurl to be added to the include path before cmcurl's, which would result
in them being picked up and causing the build to fail if the curl versions
differ too much.
One way to trigger this is to have OpenSSL installed into a non-default
location together with libcurl (/usr/local, for example). If cmcurl is built
with CMAKE_USE_OPENSSL on, -I/usr/local/include would end up being added
before -I${PATH_TO_CMCURL}.
Since commit 71b14dcb (Utilities/Release: Do not upload doc staging
tarball, 2014-02-26) the prefix upload_release.cmake computes does not
match any files when used with -DVERSION=master as has been done for the
nightly binary builds. Since the version is not actually 'master'
anyway, change the nightly binary upload logic to explicitly pass the
destination directory. Do not pass any VERSION so the default is taken
and matches the binaries.
Name the pre-built docs tarball on the remote machine according to the
release script name so that multiple tarballs going to a single remote
machine do not clobber one another.
Add SPHINX_TEXT to enable the Sphinx 'text' builder. Mark it as
advanced and do not add install rules. This is intended for use
by the release manager to build the release notes in text format
suitable for email.
Avoid requiring all build machines for the upstream packaging process to
have Python and Sphinx installed. Instead create a way to build the
documentation once on the host machine and copy it to each build machine
as a tarball with content to include in the installation tree for
packaging.

Download http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt and place

Install the license file as ${CMAKE_ROOT}/Licenses/LGPLv2.1.txt so that

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

Only temporarily until we can setup a new cygwin build machine

We can be sure that at least cmake 2.6.3 is used when building cmcurl.
This means we always get in the first branch of the if().
I think it is not a good idea to pull a cmake module from the cmake
which is being built in, since this may use features which are not
supported in the cmake which is used to build cmake (e.g. CMAKE_CURRENT_LIST_DIR
which does not exist in cmake 2.6.3 which is the minimum for cmcurl).
A bit further below there is anyway code to handle the case that cmake is
older than 2.8.0, so it should be ok.

Upstream libarchive now requires CMake 2.8 to get the newer add_test
functionality. Since we do not build libarchive's tests we do not
need the requirement.
We cannot suppress PGI compiler warnings completely because even with
the "-w" flag the compiler still writes a message containing "compilation
completed with warnings" to stderr.
A warning is triggered by expressions like
test ? NULL : ptr_to_const_char
test ? ".." : ptr_to_const_char
that the PGI compiler handles incorrectly. It chooses the pointer type
of the first option (either void* or char*) and warns about conversion
of the second without a cast. Flip the expression logic to
!test ? ptr_to_const_char : NULL
!test ? ptr_to_const_char : ".."
to help the compiler choose the proper result type.
The HP-UX <wchar.h> header provides 'mbstate_t' in C89/C90 mode only if
_XOPEN_SOURCE is defined to exactly 500. Type 'mbstate_t' was
introduced in C89/C90 Normative Amendment 1, aka C94/C95, adding support
international character sets. It is part of C99 but not C89/C90.
The parent commit only added DART_TESTING_TIMEOUT to the cache.
Also add CTEST_TEST_TIMEOUT because the logic in
CMake/Tests/CMakeLists.txt uses that variable in its "long test
timeout" computation. Now the cygwin build really does have 7200
seconds before it calls timeout death on a test.
Configure the result as definition HAVE_STRUCT_STATVFS_F_IOSIZE and use
the member only if it exists. At least one platform (IRIX) provides
struct statvfs without this member.
VS 6 warns verbosely when WINVER >= 0x0500. Avoid defining WINVER and
_WIN32_WINNT to higher than 0x0400 on VS 6. Provide missing API

<windows.h>. Provide GetVolumePathNameW because VS 6 does not declare
it regardless of the API version.
At least one compiler (Borland) defines mode_t as just "short" which is
signed. This breaks code like
switch(archive_entry_filetype(e)) {
case AE_IFREG:
...
}
if AE_IFREG and other constants have a longer signed type (int) because
sign extension of the mode_t return type from archive_entry_filetype
changes its value. Avoid the problem by ensuring the type of the
constants matches mode_t.
This change was originally made in commit a73acfbe (Fix for mode_t with
signed types, 2009-11-07). Port it to the new libarchive snapshot.
Mangle the open_FILE symbols to avoid conflict with open_file:
Warning: public '_archive_read_open_file'

This workaround should not go upstream because it will break when
mixing compilers.

Re-arrange the logic to look for KWStyle in the typical install
locations and under the Dashboards/Support directory for the

by default, thereby activating the KWStyle related custom targets
and the KWStyle test.
The older install_files command uses a leading slash in front
of the destination directory, whereas the modern signature does
not. Use the modern signature since that's what the CMake devs
are now used to.
