Each call to AddDefinition has overhead for variable watches and such.
Avoid extra calls when not needed.
This decreases the configure time for ParaView by 10 seconds on my
machine. Without the change about 1,000,000 set-to-empty calls were
being made. After the change it drops to about 100,000.
The SHA512_Update implementation accesses input data via 64-bit
integers. This requires alignment of the input buffer on some
architectures. Align our stack-allocated buffer for file content to
satisfy this requirement.
Describe explicitly the scope in which enable_language must be

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)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
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.

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.
dc1d025 OS X: Add test for rpaths on Mac.
8576b3f OS X: Add support for @rpath in export files.
00d71bd Xcode: Add rpath support in Xcode generator.
94e7fef OS X: Add RPATH support for Mac.
RPATH support is activated on targets that have the MACOSX_RPATH
property turned on.
For install time, it is also useful to set INSTALL_RPATH to help
find dependent libraries with an @rpath in their install name.
Also adding detection of rpath conflicts when using frameworks.
This fixes bug #13797.
The kinds of changes applied in 373faae5 for frameworks are now
applied to CFBundle. The prefix and suffix for CFBundles are
now handled in cmTarget::GetFullNameInternal.
This corresponds to the g++ and clang++
option -fvisibility-inlines-hidden on linux. On Windows with MinGW,
this corresponds to -fno-keep-inline-dllexport. That option is
not supported by clang currently.
This is initialized by CMAKE_<LANG>_VISIBILITY_PRESET. The target
property is used as the operand to the -fvisibility= compile option
with GNU compilers and clang.
Currently it only adds the contents of the COMPILE_FLAGS target
property, but it can be extended to handle a new COMPILE_OPTIONS
generator expression enabled property.
Process all arguments in a single loop using a simple state machine.
While at it, fix some error message typos. Also allow LINK_LIBRARIES
with no actual libraries to disable use of the -DLINK_LIBRARIES=...
from the CMAKE_FLAGS. This was already possible in the old logic if
LINK_LIBRARIES was immediately followed by another keyword argument
instead of the end of the argument list, so allow it in general.
Update the RunCMake.try_compile test cases accordingly.
3aa9ce4 GenexEval: Fix evaluation of INCLUDE_DIRECTORIES target property.
0b39fef GenexEval: Extract a getLinkedTargetsContent from TargetPropertyNode.
53164ac cmTarget: Remove some hardcoding of transitive property names.
This property should come from the content of the property itself,
plus the INTERFACE_INCLUDE_DIRECTORIES of the link *implementation*.
In contrast, when the INTERFACE_INCLUDE_DIRECTORIES is evaluated for
a target, the INTERFACE_INCLUDE_DIRECTORIES of the link *interface*
is used.
Similar logic applies for the COMPILE_DEFINITIONS target properties.
If the propertyName is already an INTERFACE_ variant of the property,
ie, the expression is similar to
$<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>
then the INTERFACE_INCLUDE_DIRECTORIES of the link *interface* of foo
is used.
However, if the propertyName is not an INTERFACE_ variant, and the
interfacePropertyName is, ie, the expression is similar to:
$<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>
then the INTERFACE_INCLUDE_DIRECTORIES of the link *implementation*
of foo is used.
This will be used to process transitive components of properties
which depend on linked targets. Currently only the link interface
of the target can be used as the source of the linked targets, but
in the next commit it will be possible to use the link implementation
as the source of link targets.
This commit does not change the semantics of the code.
Commit e65ef08b (try_compile: Fix quoting of libraries in generated
CMakeLists.txt, 2013-05-24) added quoting to entries specified in
the LINK_LIBRARIES. However, if the input entries contain whitespace
padding, that quoted whitespace causes an error in the generated
CMakeLists.txt at target_link_libraries.
Strictly, it is an error to have space separated entries in the
CMAKE_REQUIRED_LIBRARIES, as it was never properly handled by
CMakeExpandImportedTargets even prior to commit 236133e7 (Handle
targets in the LINK_LIBRARIES of try_compile., 2013-02-09). However,
it is causing a regression in KDE code which tests the next branch.
In Qt 5.1, Qt5::Core has a INTERFACE_QT_MAJOR_VERSION property
of '5', and since CMake 2.8.11, Qt4::QtCore has an
INTERFACE_QT_MAJOR_VERSION of '4'. This was introduced in
commit 4aa10cd6 (FindQt4: Set the INTERFACE_QT_MAJOR_VERSION for
Qt4::QtCore, 2013-03-16), to produce an error if Qt 4 and Qt 5
are erroneously used by the same target. This can also be used
however to determine the Qt major version, and therefore the
particular moc executable to use during automoc steps. This means
that targets in a single buildsystem can use a selection of Qt 4
and Qt 5, and still take advantage of the CMAKE_AUTOMOC feature
without conflicting.
Since commit 236133e7 (Handle targets in the LINK_LIBRARIES of
try_compile, 2013-02-09) libraries passed to the new LINK_LIBRARIES
option of try_compile are not quoted inside the generated CMakeLists.txt
file. Quote the library names so they re-parse correctly when loaded by
CMake to configure and generate the test project.

They can't be used when evaluating link libraries, but they can be
used for include directories and compile definitions. Later they can
be used for compile options.
The idea is to write to a temp file which contains generator
expressions, and at generate time, evaluate the generator expressions,
and write the result to a file.
Because executables on Windows are limited in the length of command line
it is possible to use, it is common to write command line arguments to a
file instead and specify the file as a source of arguments.
This new FILE(GENERATE) subcommand allows the use of generator
expressions to create such files so that they can be used with
add_custom_command for example.
Make handling of directory separators consistent between
non-bundle and bundle code.
Remove xcode specific flag from cmTarget when getting install_name.
Add (more) consistent convenience functions in cmTarget to get
directories inside of bundles and frameworks to add files to.
This refactor also fixes bug #12263 where frameworks
had the wrong install name when SKIP_BUILD_RPATH.
Also make install_name for frameworks consistent between Makefile
and Xcode generator.
Since commit c519bb2b (XCode: Also qoute [] as needed to set
build-configurations, 2011-04-05) we escape "[]" conditions for
XCODE_ATTRIBUTE_ settings. However, we need to handle the "variant"
condition with a special case to map it only into the settings for the
matching configuration.

Checking if a byte is 0 before checking it for something else doesn't do

.../Source/cmakewizard.cxx:70:35: warning: conversion to ‘int’ from ‘long unsigned int’ may alter its value [-Wconversion]

The compiler is (partly) right here: sizeof() returns a size_t, which often is
bigger as as int as it is unsigned long or something similar. Add an explicit
cast to get rid of that warning here, the buffer has a size of 4KiB, so the
value will fit into an int on all sane platforms.
When processing link line entries we check for matches with known naming
patterns for static and shared libraries. Teach this logic to recognize
numerical suffixes after shared library names such as "libfoo.so.1".
Generate the default AssemblerListingLocation through the flag map so
that it can be overridden by a user /Fa flag. Also teach the VS 7-9
generators to map /Fa to AssemblerListingLocation.
While at it, fix the AssemblerListingLocation default value to have a
trailing slash after the configuration name. This ensures it will be
treated as a directory and not a file name.
This allows for example, the buildsystem to use names like 'boost_any'
instead of the overly generic 'any', and still be able to generate
IMPORTED targets called 'boost::any'.
Commit 429e3699 (Process COMPILE_DEFINITIONS as generator expressions
in QtAutomoc., 2013-01-25) introduced a check for the existence of the
COMPILE_DEFINITIONS property on the target before processing it.
At the time, compile definitions from linked targets were added to the
COMPILE_DEFINITIONS property by target_link_libraries. The way such
transitive compile definitions worked was changed in subsequent
commit a1c4905f (Use the link information as a source of compile
definitions and includes., 2013-02-12), so that the COMPILE_DEFINITIONS
property may be empty, despite the fact that there are definitions
which should be used.

This generator expression joins a list with a separator. The separator
may contain arbitrary content, such as commas, which is ordinarily a

Add support to maintain designer functionality for Visual Studio C++
Windows Forms projects. Also add a test project showing how to use

Initialize the CMAKE_CONFIGURATION_TYPES cache entry early during

PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION both take a list of expressions.
Stop searching if the first of those has matched the output as the result will not

Because of clock scew between processors or just because of someone changing
the system time the end timestamp may be before the start time. Reporting a
negative time doesn't any sense, just report zero there as it already happens
for really fast tests.
The --workaround-gcc296-bugs has been part of the default Valgrind flags since
Valgrind support was added in commit 5b232ded15
(ENH: Add initial memory check support which works for Valgrind, 2003-12-15).
The Valgrind manpage says that this option should be avoided if not really
needed as it may cause real errors to get ignored. If someone uses a compiler
that really needs the flag this flag should be set by the user explicitely.
Most users will never set any flags and probably never notice that they use a
flag they shouldn't.
The memory checker command can't be quoted at this point, because previously it
has been tested that the given file exists, which will fail if the name is
quoted. The CTestTestMemcheckUnknown test aimed to test this case, has always
failed to do so and serves no useful purpose therefore.
The phrase "flag used" is somewhat imprecise, so extend it to stress
intentions.
Also correct:
- "Flag" => "Flags"
- "[CMAKE_BUILD_TYPE]" => "<CONFIG>"
dea1df4 Memoize usage requirement include directories in a config-specific map
26dba6a Fix include dir propagation from conditionally linked targets
b8259c3 Centralize maintenance of usage requirement include directories
Commit 42ebb188 (Memoize includes and defines from interface libraries.,
2013-02-22) introduced caching of the includes. Fix the memoization to
be configuration-specific so that we do not accumulate entries across
multiple evaluations in a multi-config generator.
Generator expressions, including configuration-specific expressions may
be used as link libraries of targets. The old-style keywords of
target_link_libraries are handled in terms of new generator expressions.
However, the generator expressions expect target names to be valid
against a regular expression, whereas target_link_libraries does not
require validation. In generator expression constructed without any
action from the user we need to ensure that only valid expressions are
generated. Ensure that strings which are not valid target names are not
used in generator expressions which validate the argument.
Code like
target_link_libraries(B debug A)
generates usage requirement references such as "$<$<CONFIG:DEBUG>:A>".
When cmTarget::GetIncludeDirectories uses such references it generates
expressions like:
$<TARGET_PROPERTY:$<$<CONFIG:DEBUG>:A>,INTERFACE_INCLUDE_DIRECTORIES>
When the conditions are false such references evaluate as an empty
string and the expression fails with an error such as:
$<TARGET_PROPERTY:tgt,prop> expression requires a non-empty target name.
Fix this by teaching cmTarget::GetIncludeDirectories to wrap the above
expression inside a conditional:
$<$<BOOL:$<$<CONFIG:DEBUG>:A>>:...>
so that $<TARGET_PROPERTY:...> will not be evaluated with an empty
target.
Maintain a target's internal list of usage requirement include
directories whenever the LINK_LIBRARIES property is set by either
target_link_libraries or set_property.
Re-word the documentation to make clear that CMake integrates usage
requirements during generation and not synchronously during
configuration or execution of target_link_libraries.
