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.

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

This generator expression joins a list with a separator. The separator

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

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.

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.
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.
The commit to add the INTERFACE_QT_MAJOR_VERSION in qtbase.git
is 14054d45 (Set the INTERFACE_QT_MAJOR_VERSION to 5., 2013-03-16)
which will be part of Qt 5.1.0.
If there is a Qt 5.0.3 release, there is no guarantee it will
contain that commit. Make sure such a Qt version does not fail
with this test if not.
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.
In particular, this checks that CTest's use of select() has a sufficient
file descriptor set size limit (FD_SETSIZE) to handle many child
processes at the same time. Running 20 tests requires more than 64
descriptors, the Cygwin default that we override.
Rename the variable added by commit 9ce1b9ef (Add
CMAKE_BUILD_INTERFACE_INCLUDES build-variable, 2012-11-25) to
CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE to be more consistent with the
existing CMAKE_INCLUDE_CURRENT_DIR variable.

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.
Since commit e03f83f3 (ProcessorCount test: fix path to cmsysTestsCxx
executable, 2013-01-24) the directory references a target that is not
built when BUILD_TESTING is OFF. It makes no sense to add tests without
BUILD_TESTING anyway.
While at it, use add_subdirectory instead of subdirs to add CMakeTests.

Do not use PROJECT_BINARY_DIR before it is defined. If it is not

If CMAKE_MAKE_PROGRAM is not set fail with an error message instead of
crashing. Suggest calling project() or enable_language() first to
ensure that CMAKE_MAKE_PROGRAM is set.
Move the ErrorsOFF/ON common logic from CMakeLists.txt into an
ErrorsCommon file to allow other test cases to be added that do not use
the Errors test logic.
Commit 79568f95 (automoc: Add source file to target early to set the
linker language, 2013-02-20) changed automoc initialization to a two
step process. In the first step, the generated source file was added
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.
The CMake language implicitly flattens lists so a ";" in a list element
must be escaped with a backslash. List expansion removes backslashes
escaping semicolons to leave raw semicolons in the values. Teach
ExternalData_Add_Test and ExternalData_Expand_Arguments to re-escape
semicolons found in list elements so the resulting argument lists work
as if constructed directly by the set() command.
For example:
ExternalData_Add_Test(Data NAME test1 COMMAND ... "a\\;b")
ExternalData_Expand_Arguments(Data args2 "c\\;d")
add_test(NAME test2 COMMAND ... ${args2})
should be equivalent to
set(args1 "a\\;b")
add_test(NAME test1 COMMAND ... ${args1})
set(args2 "c\\;d")
add_test(NAME test2 COMMAND ... ${args2})
which is equivalent to
add_test(NAME test1 COMMAND ... "a;b")
add_test(NAME test2 COMMAND ... "c;d")
Note that it is not possible to make ExternalData_Add_Test act exactly
like add_test when quoted arguments contain semicolons because the CMake
language flattens lists when constructing function ARGN values. This
re-escape approach at least allows test arguments to have semicolons.
While at it, teach ExternalData APIs to not transform "DATA{...;...}"
arguments because the contained semicolons are non-sensical.

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.
Move the Tests/FPHSA_InvalidFOUND_VAR test case over to a new
RunCMake.FPHSA test with a BadFoundVar case. The RunCMake tests are
built to cover failure cases easily and robustly.
Imported targets are re-exported so that they can be used by the
try_compile generated code with target_link_libraries.
This makes the use of the cmake_expand_imported_targets macro
obsolete. The macro is not able to expand the generator expressions
which may appear in the IMPORTED_LINK_INTERFACE_LIBRARIES content.
Instead it just sees them as 'not a target'.
In the new mode FPHSA now accepts a FOUND_VAR option, which can be set
either to ExactCase_FOUND or UPPERCASE_FOUND, no other values are
accepted. Also add tests for that, including failure.

Previously, GetIncludeDirectories was called before calling
target->AddSourceFile(mocCppSource). Since commit a1c4905f (Use the
link information as a source of compile definitions and
includes., 2013-02-12), the include directories are determined by
the link information.
Valid link information requires that the linker language can be
determined, which depends on the source files languages and the
dependent targets languages. In the case of the no_link_languages
target in the unit test, there are no dependencies and the additional
source file no_link_languages_automoc.cpp is added to the target
at generate-time. That file can be used to determine the linker
language, but it must be added to the target before calling
GetIncludeDirectories.
Extend the Module.ExternalData test to cover a DATA{} reference whose
name contains a space. Skip the case when the native build tool does
not support spaces.
Some make tools do not support spaces inside the source tree paths.
Decide early whether to add tests that depend on support for spaces so
we can use the result in a decision for any test.

This is needed in the case that Automoc is used, as that calls
GetIncludeDirectories, which may cache the resulting include dirs
too early in the generate step.
Also, because the automoc step is so early, we can't cache the
include directories at that point. At that point the build interface
of all dependencies are not populated yet, so we'd be caching the
includes before appending the build interface. Only start caching
when we're definitely generating the buildsystem. At that point, the
includes should be stable.
We still need to invoke AppendBuildInterfaceIncludes
in the GlobalGenerator because the build interface includes affect
mostly the dependencies of targets (such as the automoc targets),
rather than the targets themselves, so the build interface needs
to be appended for all targets before generation is done.
