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.
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.

Checkout [1] as an example of the test failures. In that particular cases, the
failures is caused by the plus sign in the path being pass unescaped
(buildd-cmake_2.8.9-1~bpo60+1-armel-3Lvkef) to the regexp.
In addition to failures in the log, the following new tests also fail in 2.8.11:

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.
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.
That will allow things like this:
find_package(Qt4)
qt4_generate_moc(myfile.h moc_myfile.cpp TARGET foo) # Note, foo target doesn't
# exist until below.
add_library(foo ...)
The qt4_generate_moc call would use the INCLUDE_DIRECTORIES from
the foo target using generator expressions. Currently it reads
the INCLUDE_DIRECTORIES directory property, meaning that include_directories()
is required.
Support for the TARGET is also added to qt4_wrap_cpp, but not qt4_automoc,
as that is deprecated in favor of the AUTOMOC target property.
The moc tool reports failure if the Q_INTERFACES macro is used with
an argument which has not appeared with Q_DECLARE_INTERFACE, so that is
the basis of the unit test.
The command line arguments are now always written to a file, which is
passed to moc as the @atfile. This was already the case on Windows, but
now it is used everywhere. The reason for that is that it is not currently
possible to expand the list of includes from a target directly in
a add_custom_command invokation (though that may become possible in the
future). There is not a big disadvantage to using the file anyway on
unix, so having one code path instead of two is also a motivation.
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.
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.
7378792 if: Add test for IS_DIRECTORY
4ab10e0 Merge branch 'master' into fix-FileIsDirectory-SEGV
045d6ae KWSys: Fix SystemTools::FileIsDirectory with long paths (#14176)
Add a RunCMake.if test to cover if() command behavior. Start with a
test for IS_DIRECTORY cases with an existing directory and a long path,
both with a trailing slash.
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.
The ExternalData_LINK_CONTENT option tells ExternalData to convert real
data files it finds into content links and to "stage" the original
content in a ".ExternalData_<algo>_<hash>" file. However, after a data
object has been staged it is possible that a user-provided pattern in
the "REGEX:" option will later match the staged object file. We must
not process staged object files even when a user pattern matches them.
Fix the implementation to not match a staged object file as a normal
data file for conversion. Extend the RunCMake.ExternalData test to
cover this case.
The VS 6 IDE does not like spaces in definition values so CMake drops
them and warns. The Tests/CompileDefinitions test C code that looks for
the dropped definitions already knows to skip them, but CMake still
warns. Silence the warnings by avoiding such values in the first place
on VS 6.
The variables in this module are used to configure a header file
with defines whose name depends on the name of the target.
As valid names of targets may be invalid for use as defines, convert
the names of the defines used to C identifiers first. This is already
done in C++ code for the DEFINE_SYMBOL property.
This is not as simple as ensuring that the BASE_NAME is a C identifier,
because most of the define names are configurable, and because use of
a BASE_NAME which is not a C identifier, such as 4square can become a
C identifier by specifying a prefix in the generate_export_header
macro.
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.
The parent commit added a empty_entry_test shared library to the
IncludeDirectories test. Some toolchains fail to create a shared
library with no user-defined symbols, so provide a dummy symbol.
a7ba452 Add the JOIN generator expression.
96ec314 Make it possible for any genex to have arbitrary content at the end.
bd638ee Rename the method determining if a genex accepts arbitrary content.
dc742fe Extract the ProcessArbitraryContent method.
Both <string> and <cmSystemTools.h> include <stdio.h> one or the other way. It
looks like the CMake header adds a define that will cause another part of the
system header to be used, resulting in conflicting definitions.
6489015 Remove an endif() followed by an if() for the same condition.
e7813b1 Add a test for Qt5Automoc
27fb96b Make the QtAutomoc test compile with either Qt 4 or Qt 5
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'.
Teach CMakeParseImplicitLinkInfo to convert the CMAKE_LINKER file name
to a regular expression that matches only the original name. Escape
special characters like '+' so they are not treated as regex syntax.
Extend the ImplicitLinkInfoTest to test handling of a CMAKE_LINKER value
with many special characters.

This generator expression joins a list with a separator. The separator
may contain arbitrary content, such as commas, which is ordinarily a
delimiter in the generator expression syntax.
Add support to maintain designer functionality for Visual Studio C++
Windows Forms projects. Also add a test project showing how to use
the CMakeLists.txt file and, when successfully configured, will allow
use of the designer for the included form.
All supported memory checkers now write their output to a file. Use a dummy
checker that ignores the given filename and ensure that the missing file is
reported as error.
The code for the tests is basically the same for all those subtests, so have
one template and configure that for as many tests as possible to make it
easier maintainable.
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 dummy memory tester implementation now understands the command line
switches for all memory checkers to redirect the output to a file. This avoids
triggering the error cases for BoundsChecker and Purify because the output file
does not exist.
Commit b8259c3d (Centralize maintenance of usage requirement include
directories, 2013-04-29) changed the handling of the property.
Previously setting the property directly instead of via
target_link_libraries would not result in transitive include
directory handling.
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.
Add test covering cmGlobalGenerator::GenerateBuildCommand for VS
solutions with MSBuild and building a target defined in a subdirectory
and not part of ALL.
Create class cmVisualStudioSlnParser as a generic parser for Visual
Studio .sln files. Implement minimum functionality but keep class
extensible. Add tests for the class.
Use the suggestion from http://support.microsoft.com/kb/2262855 to escape
semicolons in preprocessor definitions for VS >= 10. Update the
COMPILE_DEFINITIONS documentation disclaimer list of known limitations
accordingly. Update our "Preprocess" test to cover the case.
