The qtx_add_resources() macro adds the resource file to the output list
to maintain file-level dependencies. Having the qrc file in a target
sources is a precondition for AUTORCC to function.
When processing the source files of a target, only add the generated
qrc_<file>.cpp to the target sources if AUTORCC is ON. This avoids
pre-porting conflict with the macro.

Since commit v2.8.2~105^2~2 (Teach CMake Policies about tweak version
component, 2010-04-23), cmPolicies has known how to handle a policy
introduced in a tweak version. This was done back when we introduced
policies with the current development date version and later updated it
to the release version. Now we always introduce policies using the next
expected release version and explicitly set the policy to test the NEW
behavior.
CMake Policies (or any other features) should never be introduced in a
tweak (bugfix) release, so drop the infrastructure that allows this.
Set a global property in the find_package implementation. Track and
reset that property in the find_dependency macro. Read the property
in FeatureSummary when determining whether to print output.
This means that packages which are found only as dependencies are not
listed by FeatureSummary, but if a project uses find_package elsewhere
directly, then it will be listed by FeatureSummary.

holding the project version number and its components. Add project()
command option "VERSION" to specify the version explicitly, and default

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.

Teach the project() command to recognize an optional "LANGUAGES"
keyword after the project name and prior to the list of languages.
Do not allow multiple copies of the keyword. If the keyword is
specified and no languages are listed, imply NONE.
Avoid using the moc from Qt 5 with Qt 4 based targets. Moc generates
a version check to ensure that such generated code does not compile.
The Qt4And5Automoc unit test should have been testing this, but it
was not because the test was broken. In that unit test, moc was run
on trivial files which have no significant content, and in particular
no Q_OBJECT macro. Therefore moc was generating empty files which
do not even contain the version check. Fix this by generating files
for input to moc at cmake time.

Images and xib files must have 'lastKnownFileType' attribute to be
displayed correctly. If xib file has attribute 'explicitFileType' it is
displayed as raw xml. If static image has attribute 'explicitFileType'
it is displayed as question mark on storyboard.
Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.
Store variable types together with their names in the variable completion
list so that the type is automatically recovered when you select a variable.
Keep variable names and types in separate lists. This removes the :TYPE
string from completion list and the Name field and makes variable search
easier. The variable names and types are now kept in two different
settings - AddVariableNames and AddVariableTypes. Drop the old
AddVariableCompletionEntries setting.

the requested file with placeholder content explaining that the option
is not supported anymore.
In VS <= 9 we already convert include paths to use backslashes
but the conversion was left out of the VS >= 10 generator.

Since commit 56831461 (Xcode: Use explicitFileType to mark source types,

Store cmExportBuildFileGenerator instances which correspond to the

and dependencies to the bootstrap system.
Direct users of IMPORTED targets treat INTERFACE_INCLUDE_DIRECTORIES
as SYSTEM, after commit a63fcbcb (Always consider includes from IMPORTED
targets to be SYSTEM., 2013-08-29). It was intended that transitive
use of an IMPORTED target would have the same behavior, but that
did not work. The implementation processed only direct dependencies
in cmTarget::FinalizeSystemIncludeDirectories.
Implement transitive evaluation of dependencies by traversing the
link interface of each target in the link implementation.
The error messages were incorrect (reporting that the expression
requires one or two parameters), and repeated. Remove the now-unused
ZeroOrMoreParameters enum value.
There is no need to allow EXCLUDE_* properties, because an
INTERFACE_LIBRARY has no direct build output.
IMPORTED_LINK_INTERFACE_LANGUAGES are relevant only to static
libraries.
VERSION is relevant only to the filename of direct build outputs,
which INTERFACE_LIBRARY does not have.
If the dependent target sets the property to boolean false, ensure
that that appears in the debug report. Previously, the report
output contained whether the property was consistent among dependencies,
displaying 'TRUE', instead of the content of the property, which may
be 'FALSE'.
Return a std::pair from the consistentProperty method. This makes
it possible to make the return value for string types easier to
reason about. The return value of consistentProperty was previously
set to an empty static string to emulate a 'true' value for the caller
in commit 816b4a8a (cmTarget: Make consistentProperty
return consistent content., 2013-10-22). The pair makes the
consistency result properly typed.
Don't refer to 'both', but a 'mixture'. List all compatible interface
property types possible.
Add another test for a mixture of three compatibilities.
The include_directories() and add_compile_options() commands
should not append to the corresponding target property for IMPORTED
targets. This is already the case for add_definitions().
The modern way to create configuration dependent content is using
generator expressions in the main export file. The only non-deprecated
property still generated in the configuration-specific files are
IMPORTED_LOCATION_<CONFIG>
INTERFACE_LIBRARY targets have no location, and no need for those
files.
The next version is 3.0.0, not 2.8.13.
The version generated in the export file should be updated in
the release branch in both cmExportInstallFileGenerator and
cmExportBuildFileGenerator.

424d5dc kate: support also the build plugin in kate <= 4.12
8bd6cf0 kate: the prev_target is not used by kate
The <OBJECT_DIR> placeholder is supposed to be the base intermediate
files directory for the current target. This is how it gets replaced
during link line generation. However, during compile line generation
we replace it with the directory containing the current object file
which may be a subdirectory. Fix replacement of <OBJECT_DIR> in the
generated compile lines to be the base intermediate files directory.
This was expoxed by commit 42ba1b08 (VS: Separate compiler and linker
PDB files, 2013-04-05) when we added a "/Fd<OBJECT_DIR>/" flag to the
MSVC compile line in order to match the VS IDE default compiler program
database location in the intermediate files directory. For source files
in a subdirectory relative to the current target this caused the wrong
location to be used for the compiler program database. This becomes
particularly important when using precompiled headers.
While at it, use the cmTarget::GetSupportDirectory method to compute the
intermediate files directory for the current target instead of repeating
the logic in a few places.
With this patch, cmake now puts the MachO64 bit
binary file parser into the config file if the detected
Eclipse is at least Helios (7.0), otherwise with the old
parser executables will not be recognized by Eclipse.

With this patch, simply also the information used
by the build plugin in kate <= 4.12 is put into the

Teach the export command to handle export sets defined by invocations
of install(TARGETS ... EXPORT foo). This makes maintenance of targets
exported to both the build tree and install tree trivial.
The first regression resulted in endless looping due to unrun test
dependencies. The second regression prioritized all tests with dependencies
in serial test runs.
Populate a separate vector of files and append them separately. This
was the pattern used prior to commit 035b6908 (Autogen: Split AutoRcc
handling into two methods, 2013-12-10), which was erroneously not
maintained in that refactoring.
The parent commit changed the AutogensType::value_type to be
"std::pair<cmQtAutoGenerators,cmTarget const*>" but our std::make_pair
call returns "std::pair<cmQtAutoGenerators,cmTarget*>". Construct the
value_type directly instead of using make_pair. Otherwise the Sun 5.9
compiler complains
".../Source/cmGlobalGenerator.cxx", line 1281: Error:
Formal argument x of type "const std::pair<cmQtAutoGenerators, const cmTarget*>&"
in call to "std::vector<std::pair<cmQtAutoGenerators, const cmTarget*> >

passed "std::pair<cmQtAutoGenerators, cmTarget*>".
Add the .NOTPARALLEL target to each local Makefile command-line
interface entry point file so that even with -j we launch only
one "make -f Makefile2" at a time. The actual build rules
in Makefile2 and lower will still run in parallel.
Do not add .NOTPARALLEL for Borland or Watcom make tools because
they do not tolerate it. Other make tools that do not understand
.NOTPARALLEL will not be hurt.

The properties object has just been created, so is always empty,
which means the if block is never entered. The following lines do
not have any effect because an INTERFACE library has no LOCATION.
At the end, no code is generated for INTERFACE libraries in
config-specific exported files, so skip them early.
Existing single-parameter expressions work due to special casing
which assumes that if there is only one parameter, and the node
accepts arbitrary content, then the result is the input.
This is true for the existing expressions matching that
pattern - namely the "1" and "TARGET_NAME" expressions. However,
the LOWER_CASE, and UPPER_CASE expressions should also accept
arbitrary content, and in their case, the result is not the input.
Refactor the cmGeneratorExpressionEvaluator to allow that extension.
Actually evaluate the "1" and "0" nodes.
Added a new variable CPACK_WIX_PATCH_FILE that users can point at an
XML patch file. Fragments defined within the patch file will be inserted
at supported insertion points (currently Component, File and Directory).
As we're iterating over IMPORTED targets now, handle them in
the loop body. The existing behavior is harmless because generally
nothing is done anyway for IMPORTED targets in these code paths,
because they do not have sources for example.
Commit b04f3b9a (Create make rules for INTERFACE_LIBRARY
targets., 2013-08-21) extended the makefile generator to create
build targets for INTERFACE_LIBRARY targets. No other generators
were extended with this feature.
This conflicts with the feature of whitelisting of target properties
read from INTERFACE_LIBRARY targets. The INTERFACE_* properties
of the INTERFACE_LIBRARY may legitimately contain TARGET_PROPERTY
generator expressions for reading properties from the 'head target'.
The 'head target' would be the INTERFACE_LIBRARY itself when creating
the build rules for it, which means that non-whitelisted properties
would be read.
The INTERFACE_LIBRARY type does not have any LOCATION at all, so
return early from GetMappedConfig. GetMappedConfig is called from
two locations, one of which already pre-checks the INTERFACE_LIBRARY
case. Remove that pre-check and handle that case inside the method
instead.

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.
Commit 66b290e7 (export(): Process the export() command at generate
time., 2012-10-06 ) refactored export() so that it could evaluate
strings at generate-time. This was intended for evaluating target
properties, but that commit also removed a check for target
existence at configure-time. Restore that check and add a test for
this case.
Targets which link directly to themselves should not result in
generate-time errors (reported by the DAG checker).
Self-links are handled separately with policy CMP0038.

Fix logic introduced by commit eeeeca10 (XCode: Support target folders
on XCode, 2011-02-20) to avoid duplicate subfolders. The problem was
that no slash was appended to the curr_tgt_folder string on the it !=
this->TargetGroup.end() path.
This was missing from commit c34968a9 (Port some of the generator
API to cmGeneratorTarget., 2012-10-10). The generator targets
stored with the cmMakefile include IMPORTED targets, unlike the
accessor for resgular targets. Before this patch, rules would
be generated for Qt5::Core for example, which result in broken
makefiles.
Transitively consume the property from linked dependents.

This is motivated by the needs of KDE, which provides a separate

Diagnostics which check the sanity of exported include paths
previously skipped over any path containing a generator expression.
Introduce a policy to issue an error message in such cases.
The export files created in the OLD behavior are not usable, because
they contain relative paths or paths to the source or build location
which are not suitable for use on installation. CMake will report an
error on import.
Code such as
target_include_directories(foo INTERFACE
$<INSTALL_INTERFACE:include$<FOO>>
)
should be treated as a relative directory, despite the genex, after
the INSTALL_INTERFACE is stripped away.
Previously, this would generate a relative directory on export, which
would be an error on import, so no policy is needed.
Code such as
install(TARGETS ...
INCLUDES DESTINATION $<INSTALL_INTERFACE:include>
)
should behave as if the INSTALL_INTERFACE wrapper were not present.
In code such as
install(TARGETS ...
INCLUDES DESTINATION $<FOO>include
)
the generator expressions are evaluated at generate-time. Delay
determining whether each entry is a relative path until after
the generator expressions are evaluated. Such relative paths
are based relative to the CMAKE_INSTALL_PREFIX.
Treat paths which are relative and which contain a generator
expression which is not at the beginning as relative to the
source directory.
This matches the behavior of paths which are relative but contain
no generator expression at all.
Previously this would generate a relative path with the IMPORTED
target on export(), which would be a reported as a non-existent
path on import. If used directly in the buildsystem, it would be
reported as a relative path, which is also an error. There is no
need for a policy in this case.
Add the "-e" option to build.make invocations of wmake as part of
the silencing flags. From "wmake /?":
-e erase files after error (no prompt)
This prevents test timeouts on error.
As an INTERFACE_LIBRARY has no direct link dependencies, we can
short-circuit in cmGeneratorExpressionEvaluator and
in cmGlobalGenerator::CheckLocalGenerators.
As they do not generate any output directly, any generate- or install-
related code acn also be short-circuited. Many of the local generators
already do this.
Because only INTERFACE related properties make sense on INTERFACE_LIBRARY
targets, avoid setting other properties, for example via defaults.
Just enough to reach the BuildMacContentDirectory method and the
NeedRelinkBeforeInstall methods.
In the future, those methods can be moved to cmGeneratorTarget.
Define a custom ordering functor to deterministically and strictly
order the cmTarget* key. Otherwise the order would be dependent on
runtime pointer values, which breaks assumptions of some generators.
The functor orders first by target name, and then by directory. Multiple
global targets may have the same name, such as edit_cache, but their
directory differentiates them.
