GCC warns:
dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

First, it prevents a NULL dereference and second it reiterates that
targets without languages are not supported by CMake.
Add a RunCMake.ExportWithoutLanguage test exporting a library without a

Add a new signature to help populate INTERFACE_LINK_LIBRARIES and
LINK_LIBRARIES cleanly in a single call. Add policy CMP0023 to control
whether the keyword signatures can be mixed with uses of the plain
signatures on the same target.
Export the INCLUDES DESTINATION without appending to the
INTERFACE_INCLUDE_DIRECTORIES of the target itself. That way, a target
can be exported multiple times with different INCLUDES DESTINATION
without unintended cross-pollution of export sets.
It accepted an optional argument to test for equality, but no way
to get the linker language of a particular target.
TARGET_PROPERTY provides this flexibility and STREQUAL provides

We already document the variables CMAKE_<LANG>_FLAGS_{DEBUG, MINSIZEREL,

Since the ninja file isn't aware of how framework symlinks work, we
suppress symlink creation and let cmOSXBundleGenerator handle it. Also,
use the real name of framework library in build rules as was done
before, instead of the symlink.
This patch adds a comment above the block which protects
the exported targets file against multiple inclusion, to make
the file easier to understand for readers.

WiX provides a lot of functionality for installers that cannot be
supported (easily) in the default WIX.template.in file.
For most users, the default template should be fine. However if users
want to produce merge modules, include custom actions, etc, this new
option allows for a hook into how the wxs is produced.
Add an assignment operator to cmCustomCommand to copy the Backtrace

The VS IDE sets the environment variable VS_UNICODE_OUTPUT when
executing build rules in order to tell MS tools to report output through
a back door instead of through stdout/stderr. Unset this variable so
that CMake can capture or properly redirect all output from processes it
runs even when running inside a VS IDE build environment.
This generalizes the special cases fixed by commit 80d045b0 (When
GetPrerequisites.cmake runs dumpbin while running inside the VS IDE...,
2008-05-01) and commit 44aff73d (ExternalProject: Avoid bleed-through
output when logging, 2011-01-06), so drop special handling of
VS_UNICODE_OUTPUT in those instances.
Unlike other target properties, this does not have a corresponding
non-INTERFACE variant.
This allows propagation of system attribute on include directories
from link dependents.
Drop the "vsProjectFile" argument from cmTarget::TraceDependencies. It
appears to be the modern equivalent to a hunk added in commit ba68f771
(...added new custom command support, 2003-06-03):
+ name = libName;
+ name += ".dsp.cmake";
+ srcFilesToProcess.push(name);
but was broken by refactoring at some point. The current behavior tries
to trace dependencies on a source file named the same as a target, which
makes no sense. Furthermore, in code of the form
add_executable(foo foo.c)
add_custom_command(OUTPUT "${somewhere}/foo" ... DEPENDS foo)
the "vsProjectFile" value "foo" matches source "${somewhere}/foo.rule"
generated to hold the custom command and causes the command to be added
to the "foo" target incorrectly.
Simply drop the incorrect source file trace and supporting logic.
Return early in cmake::ReportUndefinedPropertyAccesses if there is no
global generator instead of opening a file and leaking the descriptor.

When the COPY_FILE operation fails optionally capture the error message
with a COPY_FILE_ERROR option instead of reporting the error
immediately. This gives callers a chance to do something else or report
the error.
Teach the RunCMake.try_compile test to cover bad argument combinations
involving COPY_FILE_ERROR. Teach the TryCompile test to cover the case
of a COPY_FILE error message captured by COPY_FILE_ERROR.
If CMAKE_<lang>_FLAGS contains quotes or other CMake language characters
they must be escaped when written into the generated CMakeLists.txt file
so that the test project parses them properly.
Teach the TryCompile test to cover this case by adding a flag with
quotes into CMAKE_C_FLAGS during a C language try_compile.
Use constructs similar to those for COMPILE_OPTIONS. This is a little
different because there is a command to remove_definitions(), so
we can't populate the equivalent target property until generate-time
in cmGlobalGenerator.
Use preprocessor loops and add a unit test for the appropriate
policies. All policies whose value is recorded at target creation
time should be part of this list.
When CMake reports failure to configure a project, especially when the
toolchain does not initialize properly, the true reason may be clear
from reading the CMakeFiles/CMake(Output|Error).log files. Advise users
to look at these files if they exist when configuration fails.
Add RunCMake.Configure test to check that the log files are mentioned
when configuration fails.
We have two mappings for the "/MAP" flag. The first does not care
whether there is a value and activates the GenerateMapFile boolean
setting. The second takes a value and puts it in the MapFileName
setting. The latter must treat the ":" as part of the flag.
This is similar to commit 8ae66bf4 (Fix optionally-valued booleans in VS
10 flag table, 2009-10-23).
The wording "Commands in the file are processed immediately as if they
were written in place of the include command" sounds as if some kind of
macro replacement is performed. This is not accurate. Update the
wording to describe behavior of the included code in terms of the
variable access scope.
Always populate the INTERFACE_LINK_LIBRARIES for interface
entries. Don't populate the old interface properties
matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?
if CMP0022 is NEW.
Because the INTERFACE_LINK_LIBRARIES property is now populated by
the target_link_libraries when operating on a static library,
make an equivalent change which populates the property with
the same value when the old link_libraries() command is used. This
silences the policy warning in that case.
This property is generated only for targets which have recorded
policy CMP0022 as NEW, and a compatibility mode is added to
additionally export the old interfaces in that case too.
If the old interfaces are not exported, the generated export files
require CMake 2.8.12. Because the unit tests use a version which
is not yet called 2.8.12, temporarily require a lower version.
This property replaces the properties which
match (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?, and is enabled
for IMPORTED targets, and for non-IMPORTED targets only with a policy.
For static libraries, the INTERFACE_LINK_LIBRARIES property is
also used as the source of transitive usage requirements content.
Static libraries still require users to link to all entries in
their LINK_LIBRARIES, but usage requirements such as INCLUDE_DIRECTORIES
COMPILE_DEFINITIONS and COMPILE_OPTIONS can be restricted to only
certain interface libraries.
Because the INTERFACE_LINK_LIBRARIES property is populated unconditionally,
we need to compare the evaluated result of it with the link implementation
to determine whether to issue the policy warning for static libraries. For
shared libraries, the policy warning is issued if the contents of
the INTERFACE_LINK_LIBRARIES property differs from the contents of the
relevant config-specific old LINK_INTERFACE_LIBRARIES property.
CMake requires the top-level CMakeLists.txt to contain a direct call to
the project() command and will insert one if there is not. Document
this requirement since some authors have tried to use include() to load
a file calling the project command.
This was missing from commit 30962029 (Make targets depend on the
link interface of their dependees., 2012-12-26), which caused
only immeditate entries of the link interface to become target
depends.
Entries from the cmMakefile are processed and maintained similarly
to other include directories. The include_directories(SYSTEM)
signature affects all following targets, and all prior targets
in the same makefile.

88d27ad Add a test to expose a bug with add_custom_command and ninja.
When converting custom commands for the ninja build system we
need to make sure that any file dependencies that exist in the build
tree are converted to phony targets. This tells ninja that these
files might not exist when starting the build, but could be generated
during the build.
This is done by tracking all dependencies for custom command targets.
After all have been written out we remove all items from the set
that have been seen as a target, custom command output, an alias,
or a file in the source directory. Anything that is left is considered
to be a file that will be generated as a side effect of another
custom command.
To properly track the usage of dependencies that are generated at
compile time as the side effect of other build steps we need
to make the WriteBuild and WritePhonyBuild commands non static

In my project group we are using CMake to generate c++/cli winform
projects and I noticed the work done in commit 79ec7868 (VS: Add Windows
Forms Support, 2013-04-29) was in the right direction for solving some
of the problems we were facing.
The changes as submitted was breaking some functionality in our
projects, so I made some changes that fixes our problems and I believe
that it will also work for others.
* Resx files did not link correctly with the winform h-file so I added
the Resx configuration to the vcxproj file.
* I removed the functionality for setting <CLRSupport> true for the
project based on if an resx-file is pressent. This is preventing
us from using native cpp code. Also this do not address that some
projects will need to set other options like clr:pure, clr:safe.
This could be implemented as a cmake option, so it is possible to
specify exactly what is needed. Existing VSWindowsFormsResx Test
project is updated so it will be working with my changes.

Currently when a configured file is removed from the build directory,
running the build command will not regenerate the file. Now detect
this and will rerun cmake properly when a user issues the build

AddCMakeDependFile and AddCMakeOutputFile both store as std::string

temporary objects, lets just use std::strings.
Through use of libarchive internally we support .zip files as well as

Expose the internal system information API to the CMake language. For

This decreases the configure time for ParaView by 10 seconds on my

The SHA512_Update implementation accesses input data via 64-bit
integers. This requires alignment of the input buffer on some

satisfy this requirement.
Describe explicitly the scope in which enable_language must be
invoked to handle all direct and indirect uses of a language.
While at it, re-word documentation of the OPTIONAL keyword to
avoid confusion over its partial implementation.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like
set(triple arm-linux-gnueabihf)
set(CMAKE_C_COMPILER "/usr/bin/clang")
set(CMAKE_C_COMPILER_TARGET ${triple})
set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
set(CMAKE_CXX_COMPILER_TARGET ${triple})
or
set(arch gcc_ntoarmv7le)
set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)

Both clang and qcc are inherently cross compiler( driver)s.
Commit 089fe1c1 (Optimize genex evaluation for includes and
defines., 2013-02-01) introduced an optimization on DAG processing
to not reprocess properties on targets which have already been seen.
This was refactored slightly in commit 8dfdf1c7 (Fix the tests for
evaluating includes and defines., 2013-02-18), but was not extended
to cover COMPILE_OPTIONS in commit 80ca9c4b (Add COMPILE_OPTIONS target
property., 2013-05-16).
This omission causes the same performance regression in running
cmake on LLVM which 089fe1c1 fixed before, but this time for the
transitive evaluation of the COMPILE_OPTIONS property.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.
The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.
Extend the signature
try_compile(RESULT_VAR <bindir> <srcfile> ...)
to allow multiple sources as
try_compile(RESULT_VAR <bindir> SOURCES <srcfile>... ...)
Process the sources to generate a CMakeLists.txt that enables all needed
languages.
Teach the TryCompile test to try cases with two sources of the same
language and of mixed languages. Teach RunCMake.try_compile to cover
error cases for the signature.
If the expression $<TARGET_PROPERTY:prop> appears in the content
of a target property, the target that prop is read from is
the 'head target' of the expression. In contexts such as evaluating
the content of a target property during generation, such
as INCLUDE_DIRECTORIES, the 'head target' is the one on which the
initial request was made.
If evaluating a generator expression which is not a target property
content, the target must be explicitly specified. Such contexts
include add_custom_command and file(GENERATE). The content might
then look like
$<TARGET_PROPERTY:tgt,prop>
However, as there is no HeadTarget set, any generator expressions
evaluated as part of reading prop from tgt which do not specify
the tgt directly report an error.
Modify the logic of the TARGET_PROPERTY generator expression so
that in such contexts, the 'head target' is set to the appropriate
target which was first encountered.
In commit 2bc22bda (Xcode: Add frameworks search paths from link
dependeny closure, 2012-12-07) we made framework search paths from the
link closure conditional on target type, skipping it on STATIC and
OBJECT library targets that do not actually link. However, the
framework search paths also influence the compile lines (-F options) so
we need them for all target types. The Makefile generator already does
this, as did the Xcode generator prior to the above-mentioned commit.
Fix the wording of the documentation for CMAKE_PARENT_LIST_FILE to
clarify that it only applies to the include stack in the current
directory. Specify exactly what commands can include files instead of
saying "somehow invoke".
It is common to specify a CMAKE_TOOLCHAIN_FILE and get a warning
for using it despite it not being used.
The WarnUnusedCliUnused test relies on the warning being emitted
each time cmake is run on an existing build. That behavior is changed
by this patch to warn only on the first invokation of CMake, and not
on subsequent invokations (because the variable is in the cache with
the same value). For that test, a clean target is added which clears
the cache and cause the warning to be emitted each time.
As the Ninja generator does not support the feature needed to test
this, it is not tested with that generator.
This command is similar to add_definitions, in that it affects
the compile options of all targets which follow it. The implementation
is similar to the implementation of the include_directories command,
in that it is based on populating a COMPILE_OPTIONS directory property
and using that to initialize the same property on targets.
Unlike the include_directories command however, the add_compile_options
command does not affect previously defined targets. That is, in
the following code, foo will not be compiled with -Wall, but bar
will be:
add_library(foo ...)
add_compile_options(-Wall)
add_library(bar ...)
Use makefile->IssueMessage() to print the unprocessed watch message in a
format consistent with other CMake messages and with a more complete
call stack for the access.
When a watch does not specify a command to call then variable_watch
prints out a message to stderr. Remove code after that which collects
all variable values to construct a message that is never printed.
Otherwise such code causes a READ_ACCESS watch to trigger on all
variables in the currents scope.
Reported-by: Yichao Yu <yyc1992@gmail.com>
In commit 9a5b4eba (All variable accesses should produce watch
callbacks, 2007-05-17) we added a new enumeration value but did not
update the list of strings matching them. Add the missing entry.
Without this, variable_watch prints REMOVED_ACCESS instead of
MODIFIED_ACCESS when set the value of the variable.
