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

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"

matching configuration.

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.

Because of clock scew between processors or just because of someone changing

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.
In commit 236133e7 (Handle targets in the LINK_LIBRARIES of try_compile,
2013-02-09) an error return case was added without closing the file in
progress. Add the missing fclose() call.
Spotted by sevenhill.
This allows the ctest_build command's TARGET option to name a target
in a subdirectory and still build properly with msbuild.
Add test case covering use of ctest_build() with such a TARGET.
In cmCTestHandlerCommand::InitialPass call InitializeHandler after setting
the CTest "SourceDirectory" and "BuildDirectory" configuration values
instead of before. This makes the values available to InitializeHandler
methods in subclasses, so also drop the duplicate configuration of those
values from cmCTestConfigureCommand::InitializeHandler.
Use cmVisualStudioSlnParser in GenerateBuildCommand() to provide correct
command line for MSBuild even when target project is stored in a
subdirectory.
Create class cmVisualStudioSlnParser as a generic parser for Visual
Studio .sln files. Implement minimum functionality but keep class
extensible. Add tests for the class.
Extend the cmGlobalGenerator::GenerateBuildCommand virtual method
signature with a "projectDir" parameter specifying the top of the
project build tree for which the build command will be generated.
Populate it from call sites in cmGlobalGenerator::Build where a
fully-generated build tree should be available.

Transform the path using ConvertToNinjaPath just as we do for all other
paths. This fixes the OutOfSource test for objects in the ../OutOfBinary
directory by computing the proper full path for the /Fd option.
The MS tools create two types of PDB files as explained here:
http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.71%29.aspxhttp://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspxhttp://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.90%29.aspxhttp://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx
One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file. Split them up.
In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".
In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically). Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.
Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files. Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.
This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.
In commit 0c727b90 (install(EXPORT): Force absolute paths for usr-move,
2013-03-08) and commit d4774140 (configure_package_config_file: force
absolute paths for usr-move, 2013-01-24) we supported Linux
distributions implementing the "/usr move" by assuming that installation
to (/usr)?/lib(64)? represents a non-relocatable system package.
When cross-compiling one may prepare a package for installation into a
system location on a target machine but install the package files on the
*host* machine inside another path for use with CMAKE_FIND_ROOT_PATH.
In this case the package development files must still be relocatable.
Handle "/usr move" with a new approach that works with relocatable
files. Teach configure_package_config_file and install(EXPORT) to
generate special logic in a package configuration file or targets file
for installation under (/usr)?/lib(64)?. Teach the file to recognize
when it is loaded through a symlink that refers to the same realpath as
its original install destination. In such a case, use the original
install prefix. Otherwise, compute the prefix relative to the current
file location to make it relocatable.
In VS IDE generators add a pre-build event to perform automoc instead of
using a separate custom target. This reduces the number of targets in the
.sln that need to be loaded by the IDE.
This also works around a VS 11 bug as discussed in issue 13900.

When called with a non-existent LHS target name the user may be trying
to add file-level dependencies. Clarify the error message to explain
the difference between target-level and file-level dependencies. Point
the reader at the commands and options needed for the latter.
We can do this check only if the TargetName is non-empty, which means
that we're evaluating INTERFACE_INCLUDE_DIRECTORIES from a linked
dependency which was set using target_link_libraries.
It is possible to have relative paths in INCLUDE_DIRECTORIES already
in CMake 2.8.10.2, so that part will require a policy to fix.
It is considered an error if the INTERFACE_INCLUDE_DIRECTORIES contains
a directory which does not exist, which indicates a programmer error
by the upstream, or a packaging error.
One of the RunCMake.CompatibleInterface tests also needs to be updated
due to this change. Non-existant includes were used in the test, but
are not needed.
Check that source and binary directories are not part of the
INTERFACE_INCLUDE_DIRECTORIES for installed IMPORTED targets.
This is limited to directories which do not contain generator
expressions to evaluate. Such paths can only be checked at time
of use of the imported target, which will be done in a follow up
patch.
The VS version we generate in the .sln header is used by VS when opening
the file through Windows Explorer and possibly elsewhere. Fix our
generators to use version strings known to VS to avoid a drop-down box.
For VS 10, since commit 4f96af44 (Fix VS 10 .sln files for Windows
Explorer, 2009-10-22) we use "Visual Studio 2010" instead of just
"Visual Studio 10". This is correct except that for the Express edition
we need "Visual C++ Express 2010".
For VS 11, since commit f0d66ab4 (VS11: Fix comment generated at the top
of *.sln files, 2011-10-20) we use "Visual Studio 11" in the .sln header
but the preferred value is "Visual Studio 2012" (just as the first
commit mentioned above fixed for VS 10). Also for the Express edition
we need "Visual Studio Express 2012 for Windows Desktop".
The API for retrieving per-config COMPILE_DEFINITIONS has long
existed because of the COMPILE_DEFINITIONS_<CONFIG> style
properties. Ensure that the provided configuration being generated
is also used to evaluate the generator expressions
in cmTarget::GetCompileDefinitions.
Both the generic COMPILE_DEFINITIONS and the config-specific
variant need to be evaluated with the requested configuration. This
has the side-effect that the COMPILE_DEFINITIONS does not need to
be additionally evaluated with no configuration, so the callers can
be cleaned up a bit too.
In some languages the compiler may need to know the path of the final
target file for which an object is being compiled. Honor the <TARGET>
placeholder for compilation rules to support such cases.
Note that this cannot work with OBJECT library targets because the final
target path is not known during compilation (there can even be more than
one final target).

The commit d2536579 (Automoc: fix regression #13667, broken build in
phonon, 2012-11-19) changed Automoc to try to re-add the Qt header dir
if it was stripped out as an implicit include from the moc command
line. When invoking a compiler, those directories are stripped out
because they are built-in, but for moc, there are no built-in directories.
The follow-up commit acc22400 (Automoc: get include dirs without
stripping implicit include dirs off, 2012-12-07) went further by not
removing the implicit include dirs, if they were specified specifically
by the user.
This had the remaining problem that the implicit include dirs appeared
in a different order of precedence for moc compared to the compiler.
Resolve that by stripping out the include dirs, where specified for
the moc command line to, and then appending them at the end. Note that
the order of the appended implicit include directories is the order
they are specified in the CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, not
the order specified by the user.

If there is a Qt 5.0.3 release, it may or may not contain the patch

Just use the workaround until 5.1.0 which certainly will contain the
fix. Don't use the workaround before Qt 5.0.0.
We can't find both preprocessing expressions at once, because then
the BUILD_INTERFACE will always be favored if both are present, even
if INSTALL_INTERFACE appears first.
This was affecting the behavior of install(EXPORT) because the
INTERFACE_INCLUDE_DIRECTORIES contained entries like
/foo/include;$<INSTALL_INTERFACE:/bar/include>
As the INSTALL_INTERFACE always evaluates to '0', it always needs
to be preprocessed properly.

to the target, which allows the link language to be determined.
However, this bypassed the check for the availability of Qt itself.
At build-time the automoc file could not be generated because the moc
tool was not available to create it.
The solution is to only add the automoc file to the target if Qt is
found.
Teach the compatibility check added by commit 042ecf04 (Add API to

If the absolute install(EXPORT) destination for the CMAKE_INSTALL_PREFIX
used during configuration is under (/usr)?/lib(64)? then assume the
current build is for a system package installation instead of a
relocatable distribution. Generate an absolute path for _IMPORT_PREFIX
in the target exports file instead of generating code to compute the
value relative to the file location. This is necessary for
distributions implementing a move to /usr such as:
https://wiki.archlinux.org/index.php/DeveloperWiki:usrlib
"All files in the /lib directory have been moved to /usr/lib and now
/lib is a symlink to usr/lib."
The relative path computation is not reliable because the targets file
could be installed through cross-prefix a symlink and loaded without it
or vice versa.
A similar change was made for package configuration file generation by
commit d4774140 (configure_package_config_file: force absolute paths for

Commit a1c4905f (Use the link information as a source of compile
definitions and includes., 2013-02-12) introduced the use of link
information as the source of target properties via the TARGET_PROPERTY
generator expression. This generator expression has a strict
interpretation of a valid target name and emits a fatal error for
invalid names.
Ensure that only targets with names valid for use with TARGET_PROPERTY
or targets which are determined by generator expressions are processed
by it. This means that at worst, invalid target names do not participate
in the transitive evaluation of properties, but the validation
generator expression can be extended where needed to resolve that.

Use the /STACK: flag to pass the value through flag parsing so that the
generator converts it to the StackReserveSize project file option. The
option was accidentally left out by commit 7491f529 (first pass at VS
10, 2009-06-25).

As of commit 1da75022 (Don't include generator expressions in
old-style link handling., 2012-12-23), such entries are not
included in the LinkLibraries member. Generator expressions in
LinkLibraries are not processed anyway, so port to the new way
of getting link information.
In the case of input like
foo$<1:bar>
the preGenex should be 'foo'. In that case, the search for a ';'
will not find one, and there is no preceding input to process as a
non-genex list.
Previously, the result of 'splitting' such a string would instead
be a vector containing the same string two times.

This reverts commit 2bee6f5ba5.
This expression is not used, and has a semantic which is not completely
optimal (namely considering utility targets to be targets, though
usually we are interested in linkable targets).
Remove it so that we have more freedom to define better expressions in
the future.

This is similar in spirit to commit e48d8420 (Cache context-independent
includes on evaluation., 2013-02-03), but it is needed since commit
a1c4905f (Use the link information as a source of compile definitions
and includes., 2013-02-12), which changed how includes and defines
are determined. As they are now determined through the link interface,
we need to cache the result of evaluating them through that.
In the case of the includes, the result was already being cached
and then immediately disposed. Store the result as a member variable
instead to make use of the caching.
We should also check whether the INTERFACE_ variant of a property
is being read, and in the case of the compile definitions, we should
test the _<CONFIG> suffixed variants. That is already available
through the use of the methods.
This way, we use the ALREADY_SEEN optimization when evaluating
the includes of a target in 'external' generator expressions, ie, those
used in a add_custom_command invokation, as opposed to evaluating the
INCLUDE_DIRECTORIES of a target itself via GetIncludeDirectories.
This means that we can use expressions of the form
$<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>
to get a list of the interface include directories of foo, including
those coming from dependencies.
We can't have a test of a target which has a single include directory in
its INCLUDE_DIRECTORIES because the shell on the MSYS platforms transforms
a single include directory to include a prefix, which is not what the test
expects. We test a target with two directories instead as a means to
test a target with no link dependencies.
Before this patch, the following is reported falsely as a self-reference:
target_link_libraries(empty2 LINK_PUBLIC empty3)
target_link_libraries(empty3 LINK_PUBLIC empty2)
add_custom_target(...
-DINCLUDES=$<TARGET_PROPERTY:empty2,INTERFACE_INCLUDE_DIRECTORIES>
)
The reason is that the existing code assumed that all reading of
include directories would be done through cmTarget::GetIncludeDirectories()
and would therefore be initialized with a DagChecker. That is not the case
if reading the property with an 'external' generator expression.
There is a test for this since commit 8e756d2b (Tolerate cycles in
shared library link interfaces (#12647), 2012-01-12), so make sure
it continues to pass, even as we require no self-references in new
INTERFACE_ property generator expressions.
