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.
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.

4e5cb37 Refactor RunCMake.build_command test to allow more cases
Do not use PROJECT_BINARY_DIR before it is defined. If it is not
defined when needed, fail with an error message suggesting that the
project() command be invoked first.
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.

Extend the range of valid target names with the + sign. This character
can commonly be used for target names, such as those containing 'c++'.
Add a test but skip it for Borland and Watcom tools which do not support
the character.

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.

Update the unit test introduced in commit 57175d55 (Only use early

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.
