13684e2b cmMakefile: Port PolicyOptionalWarningEnabled to string APIs
8018fcca Merge branch 'master' into revise-compiler-id-policies
a41c0a9d Do not warn by default when policy CMP0025 or CMP0047 is not set
d339653e Help: Revise and format policy CMP0025 and CMP0047 docs
Extend the cmGeneratorExpressionDAGChecker with an interface
returning the name of the top target. Use that to determine
when there is a DAG violation, as required by the RunCMake.Languages
tests.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc. To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.
This commit may be reverted in the future if a solution to the
above difference is implemented.
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project. Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.
This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior. When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.
Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.
As well as the traditional variables, providing imported targets is
suggested, and the relative advantages and disadvantages briefly
discussed.
A mini-tutorial walking through creating a simple find module is
provided.
This changes the recommended version variable from Foo_VERSION_STRING to
Foo_VERSION, because there is really no need to have different variable
names for package version files vs. find modules. It notes the old
variable name, though, and suggests setting it for compatibility.
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties. Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important. Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.
People will be tempted to put things there for convenience, thereby
causing conflicts similar to
http://thread.gmane.org/gmane.comp.compilers.clang.devel/35162/focus=35169
where it is conceivable that the LLVM developers could put a flag on
a target for convenience, which would cause conflicts for some downstreams.
4271a4ed Help: Add information about INTERFACE_AUTOUIC_OPTIONS.
7935f4de Help: Note that AUTOMOC consumes the defines and includes from targets.
2739a6f9 Help: Move Qt tool invocation information to a generic cmake-qt manual.
Add an introduction about the use of different package types, and the
ability to use Qt 4 and 5 versions together in a single buildsystem.
Add a section about automatic linking of the qtmain.lib library and
how to disable it.
Teach the project() command to set variables
{PROJECT,<PROJECT-NAME>}_VERSION{,_MAJOR,_MINOR,_PATCH,_TWEAK}
holding the project version number and its components. Add project()
command option "VERSION" to specify the version explicitly, and default
to the empty string when it is not given.
Since this clears variables when no VERSION is given, this may change
behavior for existing projects that set the version variables themselves
prior to calling project(). Add policy CMP0048 for compatibility.
Suggested-by: Alex Neundorf <neundorf@kde.org>
Introduce policy CMP0047 to control resetting the id for
compatibility.
De-duplicate content in the QNX platform file by including the GNU
one. QNX is a form of GNU platform.
Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They
are populated again later by the Compiler/GNU.cmake file anyway.
Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC
compiler id is in use, and the language is CXX. Use the QNX
recommended flag for QCC instead of the gcc compatible -x flag.
Populate new module files to handle system includes and depfiles
when using the QCC compiler.
Remove code which unsets the system include and depfiles related
variables. When a GNU driver is used instead of the QCC one, the
appropriate flags will be used. These variables were previously
cleared for lowest-common-denominator compatibility with both
drivers.
Define a new 'CMAKE_CONFIGURE_DEPENDS' directory property that projects
can use to specify input files to the CMake configuration process.
Extend the RunCMake.Configure test to verify that the build system
re-runs CMake when this input changes.
Add documentation entries for variables
CMAKE_OSX_ARCHITECTURES
CMAKE_OSX_DEPLOYMENT_TARGET
CMAKE_OSX_SYSROOT
Explain what each does and when/how they should be set.
Remove independent doc listing for Qt4ConfigurationSettings, Qt4Macros
and UseQt4. These are implementation details.
Recommend the use of IMPORTED targets.
Remove references to the UseQt4 file, which is obsolete in light of
the IMPORTED targets.
Add documentation for automatic tool invocation and options.
Remove reference to variables which should not be needed in modern
implementations.

Fix an off-by-one error in
GeneratorExpressionContent::EvaluateParameters exposed by a unit test.
Remove the test for 'bad' nullary use of $<CONFIG>.
Add a unit test to verify that $<CONFIG> and $<CONFIGURATION> have
the same value.
Describe how to define a buildsystem of binary targets, how to
express dependencies between them, how to add build specifications,
how to specify usage requirements, transitive and compatible
propagation and the various pseudo targets.
There is not really any need to. Downstreams can either rely on it
being provided by CMake, or copy and distribute it.
Change the documented include for the find_dependency macro.
Since commit 5f5c92b9 (VS: Add internal APIs to find MSBuild,
devenv/VCExpress, and msdev, 2013-11-13) the VS generators have
known how to lookup the locations of their build tools directly.
Expose this information to CMake language code by defining new
variables to hold the paths to these tools.

Transitively consume the property from linked dependents.
Implement configuration-specific support by following the pattern
set out for compile definitions and includes in cmQtAutoGenerators.
Implement support for origin-tracking with CMAKE_DEBUG_TARGET_PROPERTIES.
This is motivated by the needs of KDE, which provides a separate
translation system based on gettext instead of the Qt linguist
translation system. The Qt uic tool provides command line options
for configuring the method used to translate text, and to add an
include directive to the generated file to provide the method.
http://thread.gmane.org/gmane.comp.kde.devel.frameworks/7930/focus=7992
Implement the interface to provide the uic options as a usage-requirement
on the KI18n target, as designed for KDE.
