This is especially important for the Visual Studio 10
generator and its quirky current working directory
behavior.
Also, emit more information about exactly what files are
out of date when cmakeCheckStampFile returns false.
Commit 02f7cfbc (Need to remove the MAKEFLAGS when cmake starts,
2003-05-13) removed the MAKEFLAGS environment variable when CMake starts
to prevent try_compile() from inheriting "make -i". This is unnecessary
in script mode (cmake -P). Instead remove the variable only when
configuring a project.
The Eclipse and KDevelop generators set the VERBOSE environment variable to
TRUE in the project files, because they must be able to "see" the full
command lines and errors, otherwise they can't parse the errors. But the
VERBOSE env.var. also enables cmakes own verbose output, which can be quite
long. This commit introduces an environment variable CMAKE_NO_VERBOSE, which
when set disables cmake's verbose output also when VERBOSE is set. This
env.var is now set by both the Eclipse and the KDevelop generators.

The DumpDocumentation executable and some supporting code and tests were
completely unused by CMake. Generation of documentation is done by the
individual executables with --help* options. In this commit we simply
remove the unused code, executable, and test.
Versioned UNIX libraries and executables produce multiple names for a
single target using one of
cmake -E cmake_symlink_library
cmake -E cmake_symlink_executable
to create symlinks to the real file for the extra names. However, when
cross-compiling from Windows to Linux we cannot create symlinks. This
commit teaches CMake to make copies instead of symbolic links when
running on windows. While this approach does not produce exactly what
Linux wants to see, at least the build will complete and the binary will
run on the target system. See issue #9171.
We factor the implementation of
cmake -E cmake_symlink_library
cmake -E cmake_symlink_executable
out of cmake::ExecuteCMakeCommand into methods
cmake::SymlinkLibrary
cmake::SymlinkExecutable
plus a helper method cmake::SymlinkInternal.
The commit "Really fix color check for dependency scanning" disabled
color unless "make COLOR=ON" is specified. This restores the previous
default behavior when CMAKE_COLOR_MAKEFILE is ON while retaining the
previous commit's fix. See issue #9680.
The commit "Fix color check for dependency scanning" was meant to
disable color if CMAKE_COLOR_MAKEFILE was off. It did remove use of the
activation option '--color' but it failed to make the default false when
the option was missing. This commit corrects that. See issue #9680.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
The commit "Remove barely-used cmMakefile::AddCacheDefinition" removed
all but one use of the cmCacheManager method 'bool' overload. This
commit removes the other use and the entire method, thus reducing code
duplication.
When CMake is invoked by the VS IDE re-run rule we compute whether or
not CMake really needs to re-run based on some timestamp helper files.
Previously we assumed that if the main generate.stamp file exists then
VS has correctly detected that the file is out of date. However, this
assumption is too aggressive and re-runs CMake unnecessarily sometimes.
This commit removes the assumption and always checks timestamps itself.
The change breaks the explicit user re-run request (R-click -> Compile)
but only in cases when the build system is already up to date.
All global generator CreateLocalGenerator methods automatically
initialize the local generator instances with SetGlobalGenerator. In
several places we were calling SetGlobalGenerator again after receiving
the return value from CreateLocalGenerator. The double-initializations
leaked the resources allocated by the first call to SetGlobalGenerator.
This fix removes the unnecessary calls.
This extends the "-E" command line mode with a "rename old new"
signature. The new command atomically renames a file or directory
within a single disk volume.
This creates global property RULE_MESSAGES which can be set to disbale
per-rule progress and action reporting. On Windows, these reports may
cause a noticable delay due to the cost of starting extra processes.
This feature will allow scripted builds to avoid the cost since they do
not need detailed information anyway. This replaces the RULE_PROGRESS
property created earlier as it is more complete. See issue #8726.
This creates global property RULE_PROGRESS which can be set to disbale
per-rule progress reporting. On Windows, progress reports may cause a
noticable delay due to the cost of starting an extra process. This
feature will allow scripted builds to avoid the cost since they do not
need detailed progress anyway. See issue #8726.
This moves the version numbers into an isolated configured header so
that not all of CMake needs to rebuild when the version changes.
Previously we had spaces, dashes and/or the word 'patch' randomly chosen
before the patch number. Now we always report version numbers in the
traditional format "<major>.<minor>.<patch>[-rc<rc>]".
We still use odd minor numbers for development versions. Now we also
use the CCYYMMDD date as the patch number of development versions, thus
allowing tests for exact CMake versions.
This cleans up the 'cmake --build' command-line interface:
- Rename --clean to --clean-first to better describe it.
- Replace --extra-options with a -- separator to simplify passing of
multiple native build tool options.
- Document the options in the main CMake man page description of the
--build option, and shares this with the usage message.
- Require --build to be the first argument when present.
- Move implementation into cmakemain where it belongs.
This teaches the helper commands 'cmake -E cmake_symlink_executable' and
'cmake -E cmake_symlink_library' to remove broken symlinks before
creating a symlink and report an error when the symlink cannot be
created. See issue #8654.
This defines global, directory, and target properties
RULE_LAUNCH_COMPILE, RULE_LAUNCH_LINK, and RULE_LAUNCH_CUSTOM. Their
values specify 'launcher' command lines which are prefixed to compile,
link, and custom build rules by Makefile generators.
When testing whether to re-run CMake, a byproduct may be a symlink. If
so, the existence of the link is important rather than the link's
target. See issue #8465.
App Bundle and Framework directories, symlinks, and Info.plist files we
create during generation are byproducts, not outputs. We should re-run
CMake only when they are missing, not when they are old.
See issue #8465.
This teaches cmMakefile::GetProperty and cmake::GetProperty methods to
return NULL when the property name is NULL, making them more robust and
consistent with the behavior of cmTarget::GetProperty.
OpenBSD shared libraries use a ".so.<major>.<minor>" extension and do
not have a symlink with just a ".so" extension. Its "ld" is capable of
finding the library with the best version. This change adds support for
finding such libraries. See issue #3470.
The set_property command unsets a property if it is given no value. In
the case of GLOBAL properties, the cmake::SetProperty method would
replace a NULL value with "NOTFOUND". Instead it should be left as NULL
so that the property is unset as expected. Once it is unset the
get_cmake_property command will still report NOTFOUND while the
get_property command will return the empty string as documented.
- We used to always put LIBRARY_OUTPUT_PATH and EXECUTABLE_OUTPUT_PATH
in the cache if the project did not.
- In CMake 2.6 these variables should no longer be used.
- Now add them only if CMAKE_BACKWARDS_COMPATIBILITY is also cached.
- This happens only when CMP0001 is set to OLD or WARN or if
the user or project sets it. In any case compatibility is needed.
- Reported by Miguel A. Figueroa-Villanueva and Philip Lowman.
the argument after -Wno-dev was skipped, which happened to be the source
directory, and so the current working directory was assumed as source
directory, although it was the build directory (maybe this didn't have an
effect if there was already a CMakeCache.txt in the build dir)

- CMake 1.8 and below did not do the check but could get in
infinite loops due to the local generate step.
- CMake 2.0 added the check but failed to perform it in directories
with no targets (see bug #678).
- CMake 2.2 removed the local generate which fixed the problem but
did not remove the check.
- Between CMake 2.4 and 2.6.0rc6 the check was fixed to work even
when no targets appear in a directory (see bug #6923).
- Bottom line: the check is no longer needed.
- Add cmListFileBacktrace to record stack traces
- Move main IssueMessage method to the cmake class instance
(make the backtrace an explicit argument)
- Change cmMakefile::IssueMessage to construct a backtrace
and call the cmake instance version
- Record a backtrace at the point a target is created
(useful later for messages issued by generators)
- ZERO_CHECK should check all stamps in case
of parallel build (fixes complex test failure)
- ZERO_CHECK should not appear when
CMAKE_SUPPRESS_REGENERATION is on (fixes bug 6490)
- Remove CMP_0001 (no slash in target name) and restore
old CMAKE_BACKWARDS_COMPATIBILITY check for it
- Replace all checks of CMAKE_BACKWARDS_COMPATIBILITY
with cmLocalGenerator::NeedBackwardsCompatibility calls
- Create new CMP_0001 to determine whether or not
CMAKE_BACKWARDS_COMPATIBILITY is used.
(old = use, new = ignore)
- Show CMAKE_BACKWARDS_COMPATIBILITY in cache only when
CMP_0001 is set to OLD or WARN
- Update documentation of cmake_policy and cmake_minimum_required
to indicate their relationship and the 2.4 version boundary
- When no cmake policy version is set in top level makefile
implicitly call cmake_policy(VERSION 2.4) which restores
CMAKE_BACKWARDS_COMPATIBILITY and other 2.4 compatibility
- Fix tests MakeClean and Preprocess to call
cmake_policy(VERSION 2.6) because they depend on new policies
- Cycles may be formed among static libraries
- Native build system should not have cycles in target deps
- Create cmComputeTargetDepends to analyze dependencies
- Identify conneced components and use them to fix deps
- Diagnose cycles containing non-STATIC targets
- Add debug mode property GLOBAL_DEPENDS_DEBUG_MODE
- Use results in cmGlobalGenerator as target direct depends
