The CMake_TEST_EXTERNAL_CMAKE option added by commit 9608ef6f (Tests:
Optionally configure tests exclusively, 2014-03-03) is intended to allow
one to run the CMake test suite with a compiler that may not be
supported for hosting the build of CMake itself. However, we currently
use the CMake test infrastructure to test KWIML everywhere that CMake
supports. In order to continue testing KWIML even in places that CMake
itself does not build, include it even when testing an external CMake.
Add an undocumented CMake_TEST_EXTERNAL_CMAKE option to name an external
CMake 'bin' directory. Skip all main CMake binary builds and instead
configure the Tests directory to run using the external CMake provided.
This will provide a means to exercise the CMake test suite generating
for target platforms and compilers with which the CMake source does not
build. That will allow us to raise the level of C++ features required
of a compiler to build our source while retaining tests for generating
projects with older compiler tools.
Drop the option to test with a different generator and make program than
was used to build. This was used only to test support for the Open
Watcom compiler which at one time could not build CMake. Instead we
will allow CMake to be configured to skip building binaries and just run
the test suite using an external CMake (in a future change).
For now leave the two option variables hard-coded to the old option
defaults until code can be updated to stop using them.
Always name the application bundle "CMake.app". Users can rename it
after installation if they wish. This is the typical approach used by
OS X applications, including Xcode. It allows CMake to be upgraded
without manually re-running CMake in every build tree to update the path
to CMake. It also makes the executable location in the CMake build tree
more predicatable.
Install the Help directory next to Modules to make it available in CMake
distributions. Use cmRST to read Help .rst documents and print them as
help output.
Add options
--help-manual-list
--help-manual
to list available manuals or print one of them. Implement the options
--help-commands
--help-modules
--help-policies
--help-properties
--help-variables
by mapping to the corresponding manual page. Implement the options
--help-command-list
--help-module-list
--help-policy-list
--help-property-list
--help-variable-list
by globbing the available Help .rst documents of the corresponding type
and reading their titles. Implement the options
--help-command
--help-module
--help-policy
--help-property
--help-variable
by globbing the matching Help .rst document(s) and printing them.
With our modern development workflow it is less likely a property will
be added to C++ code without documentation. This mode only existed to
support the DocTest which had very limited coverage of the properties
anyway.
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.
Move logic to compute CMake_VERSION out of the top-level CMakeLists.txt
file to a dedicated Source/CMakeVersionCompute.cmake module and include
it from the original location. This will allow it to be re-used.
This allows the use of the $<TARGET_FILE:...> generator expression as a
replacement for the use of the LOCATION target property. The use of the
LOCATION target property is now deprecated for in-build targets.
Also drop other checks for older CMake versions:
* Simplify cmake_set_target_folder macro.
* Use find_package(LibArchive) unconditionally.
* Simplify condition for running testVisualStudioSlnParser test.
* Convert two macros to functions.
* Unconditionally run the CTestTestRerunFailed test.
CMake is aware of the policy's NEW behavior and the AppleClang compiler
id. Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.
Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.
Ensure CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR are always
relative paths in CMake code, and set defaults accordingly. Use the
install() command instead of install_files() and install_targets().
This is more modern and also avoids stripping of the first character
from user-specified destinations.
While at it, fix the default destinations reported in the bootstrap
help.
The KWSys "EncodeExecutable" and "ProcessFwd9x" executables were dropped
from KWSys along with Win9x Process support. Drop references from the
rest of the CMake build rules.
The warnings are enabled for now only when using GCC 4.2 or later.
It may be possible later to also enable them when building CMake
with clang. Don't duplicate the compiler flags if already set.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
Update the requirement specified in the top-level CMakeLists.txt file.
Drop the special-case minimum required version of 2.8.0 because the new
minimum subsumes it.
Revert commit 6c611c6b (libarchive: Restore CMake 2.6.3 as minimum
version, 2012-01-05) since our requirement now subsumes libarchive's.
Move the CMake version number components out of "CMakeLists.txt" into
dedicated file "Source/CMakeVersion.cmake". Set the TWEAK level to the
date explicitly. Add a "Source/CMakeVersion.bash" script to update the
date, thus replacing KWSys DateStamp for CMake. Teach the bootstrap
script to extract the version components from their new location.

You cannot set a property on a target that's not there, and
these targets are not there when BUILD_TESTING is OFF.
Thanks to Sankhesh Jhaveri for the bug report.
This adds the ability for packagers to specify that some libraries
should use system versions and others should use the CMake versions.
This allows a bit of flexibility and means Homebrew (an OSX package
manager) no longer has to continue to patch the CMake build process.

One of Cygwin's goals is to build projects using the POSIX API with no
Windows awareness. Many CMake-built projects have been written to test
for UNIX and WIN32 but not CYGWIN. The preferred behavior under Cygwin
in such projects is to take the UNIX path but not the WIN32 path.
Unfortunately this change is BACKWARDS INCOMPATIBLE for Cygwin-aware
CMake projects! Some projects that previously built under Cygwin and
are Cygwin-aware when they test for WIN32 may now behave differently.
Eventually these projects will need to be updated, but to help users
build them in the meantime we print a warning about the change in
behavior. Furthermore, one may set CMAKE_LEGACY_CYGWIN_WIN32 to request
old behavior during the transition.
Normally we avoid backwards incompatible changes, but we make an
exception in this case for a few reasons:
(1) This behavior is preferred by Cygwin's design goals.
(2) A warning provides a clear path forward for everyone who may see
incompatible behavior, and CMAKE_LEGACY_CYGWIN_WIN32 provides a
compatibility option. The warning and compatibility option both
disappear when the minimum required version of CMake in a project is
sufficiently new, so this issue will simply go away over time as
projects are updated to account for the change.
(3) The fixes required to update projects are fairly insignificant.
Furthermore, the Cygwin distribution has no releases itself so project
versions that predate said fixes tend to be difficult to build anyway.
(4) This change enables many CMake-built projects that did not
previously build under Cygwin to work out-of-the-box. From bug #10122:
"I have built over 120 different source packages with (my patched)
CMake, including most of KDE4, and have found that NOT defining
WIN32 on Cygwin is much more accurate." -- Yaakov Selkowitz
A fully compatible change would require patches on top of these project
releases for Cygwin even though they otherwise need not be aware of it.
(5) Yaakov has been maintaining a fork of CMake with this change for the
Cygwin Ports distribution. It works well in practice. By accepting the
change in upstream CMake we avoid confusion between the versions.
CMake itself builds without WIN32 defined on Cygwin. Simply disable
CMAKE_LEGACY_CYGWIN_WIN32 explicitly in our own CMakeLists.txt file.
Visual Studio Express editions do not support solution folders,
so default behavior should be as if USE_FOLDERS global property
is OFF.
Also, allow folder names to be the same as target names: internally,
use a prefix to distinguish folder GUIDs from target GUIDs. Add
a target and folder with the same name in the ExternalProject
test to exercise this code.
For CMake itself, provide a new option CMAKE_USE_FOLDERS that
defaults to ON so that Visual Studio users get a nicely organized
CMake project. Express edition users will have to turn off the
CMAKE_USE_FOLDERS option in order to build CMake in the VS Express
IDE.
This work was started from a patch by Thomas Schiffer.
Thanks, Thomas!
See the newly added documentation of the FOLDER target
property for details.
Also added global properties, USE_FOLDERS and
PREDEFINED_TARGETS_FOLDER. See new docs here, too.
By default, the FOLDER target property is used to organize
targets into folders in IDEs that have support for such
organization.
This commit adds "solution folder" support to the Visual
Studio generators. Currently works with versions 7 through
10.
Also, use the new FOLDER property in the ExternalProject
test and in the CMake project itself.
Add option CMAKE_USE_SYSTEM_BZIP2 and enable it automatically when
CMAKE_USE_SYSTEM_LIBRARIES is on. While we're at it, remove XMLRPC from
the list of system library options because we no longer provide it in
source.
Move lines from commit 696a0af (Disable gcc 33 on OpenBSD because it
crashes CPack by default, 2010-06-25) further down in CMakeLists.txt so
that CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS applies. This fixes the code for
building with CMake 2.4.
Make sure no one tries to use gcc 33 based tools to build CMake.
This is because a cpack test failed with a crash. The crash
seems to be caused by the stack checking code on by default in
OpenBSD. The crash is in some stl code. The problem is fixed
with newer gcc compilers on OpenBSD.
Override CMAKE_DOC_DIR and CMAKE_DATA_DIR cache entries on Cygwin early
enough so the new values are used everywhere. Previously only some of
the uses were overridden. Also set CPACK_PACKAGE_VERSION to the whole
CMake_VERSION so that the Cygwin MANIFEST file goes in the proper path.
Merge the release branch into master to get its version number, tags,
and ChangeLog. Revert the version on master from 2.9 back to 2.8.
Future releases will be prepared directly in master.
This is the starting point for a branchy workflow based on one described
by the "git help workflows" man page. New development will be done on
local topic branches. Topics will be published by merging them into one
of the integration branches:
maint = Maintenance of previous release
master = Preparation of future release
next = Development of features ("next" to be merged into master)
In order to bootstrap the topic-based workflow from here, all changes in
master since the 2.8 release branch started will either be included in
the next release or reverted and recreated on a topic branch.
