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.
For builds from Git repositories, add "-g<commit>" to the end of the
version number. If the source tree is modified, append "-dirty".
For builds from CVS checkouts, add "-cvs-<branch>".
Prepare to switch to the workflow described by "git help workflows". In
this workflow, the "master" branch is always used to integrate topics
ready for release. Brand new work merges into a "next" branch instead.
We need a new versioning scheme to work this way because the version on
"master" must always increase.
We no longer use an even/odd minor number to distinguish releases from
development versions. Since we still support cvs checkout of our source
tree we cannot depend on "git describe" to compute a version number
based on the history graph. We can use the CCYYMMDD nightly date stamp
to get a monotonically increasing version component.
The new version format is "major.minor.patch.(tweak|date)". Releases
use a tweak level in the half-open range [0,20000000), which is smaller
than any current or future date. For tweak=0 we do not show the tweak
component, leaving the format "major.minor.patch" for most releases.
Development versions use date=CCYYMMDD for the tweak level. The
major.minor.patch part of development versions on "master" always
matches the most recent release.
For example, a first-parent traversal of "master" might see
v2.8.1 2.8.1.20100422 v2.8.2
| | |
----o----o----o----o----o----o----o----o----
Since the date appears in the tweak component, the next release can
increment the patch level (or any more significant component) to be
greater than any version leading to it. Topic branches not ready for
release are published only on "next" so we know that all versions on
master lead between two releases.
If defined and non-empty, the value of CMAKE_TESTS_CDASH_SERVER should point
to a CDash server willing to accept submissions for a project named
PublicDashboard. On machines that also run a CDash dashboard, set this
variable to "http://localhost/CDash-trunk-Testing" so that the CMake tests
that submit dashboards do not have to send those submissions over the wire.
The CTestSubmitLargeOutput test runs a dashboard that has a test that produces
very large amount of output on stdout/stderr. Since we do not even want to
attempt to send such large output over the wire, this test is off by default
unless the CMAKE_TESTS_CDASH_SERVER server is localhost. This test is expected
to cause a submission failure when sent to CDash. It passes if the submit
results contain error output. It fails if the submit succeeds.
CMAKE_TESTS_CDASH_SERVER: CDash server used by CMake/Tests.
If not defined or "", this variable defaults to the server at
http://www.cdash.org/CDash.
If set explicitly to "NOTFOUND", curl tests and ctest tests that use the
network are skipped.
If set to something starting with "http://localhost/", the CDash is expected
to be an instance of CDash used for CDash testing, pointing to a
cdash4simpletest database. In these cases, the CDash dashboards should be
run first.
We disallow try_run() when CMAKE_TRY_COMPILE_OSX_ARCHITECTURES is set
because the binary might not be able to run on the host architecture.
This prevents us from creating ppc test binaries on i386 Mac machines
that cause Rosetta install dialogs to appear.
We create option CMake_TEST_INSTALL to enable a new CMake.Install test.
It tests running the "make install" target to install CMake itself into
a test directory. We enable the option by default for dashboard builds.
We configure an EnforceConfig.cmake script to load at CTest time.
Previously we loaded it from Tests/CTestTestfile.cmake, but now we load
it from the top level so it applies to all tests.
CMake 2.8.0 and below use the EXECUTABLE_OUTPUT_PATH setting from the
top-level CMakeLists.txt file to compute the location of the "cmake"
target for the special case of installing cmake over itself.
The commit "Clean up CMake build tree 'bin' directory" moved the setting
of EXECUTABLE_OUTPUT_PATH that affects the "cmake" target into the
Source subdirectory. This broke the special-case lookup in the top
level. We fix it by setting EXECUTABLE_OUTPUT_PATH at the end of the
top-level CMakeLists.txt file. Now that we use add_subdirectory to
process the subdirectories in order, this setting does not affect the
subdirectories. Thus we fix installation while preserving the clean
build tree 'bin' directory intended by the above-mentioned commit.
We switch CMake's own top-level CMakeLists.txt file to use the modern
add_subdirectory() command instead of the old subdirs() command. This
enables in-order processing.
We re-arrange EXECUTABLE_OUTPUT_PATH settings to avoid putting utility
and test executables in the 'bin' directory of the build tree. This
makes the directory look like that in the installation tree, except that
on multi-configuration generators we still use a per-config
subdirectory.
The commit "Cleanup regular expressions" removed real include filter
expressions and replaced them with lines like
INCLUDE_REGULAR_EXPRESSION("^.*$")
that do no filtering. We simplify the change by removing the lines
altogether.
