Custom command path normalization added in commit v3.1.0-rc1~471^2
(add_custom_command: Normalize OUTPUT and DEPENDS paths, 2014-05-28)
broke use of OBJECT_DEPENDS to bring in custom commands because the
latter paths were not normalized too. Normalize them and add a test
case.

With the Makefile generators we expect that touching or modifying the
input file of a configure_file, or removing its output, will cause CMake
to re-run on the next build. Extend the RunCMake.configure_file test
with a case covering this. Also check that CMake does not re-run if
nothing has changed.
With the Makefile and Ninja generators we expect that touching the input
source file for a try_compile will cause CMake to re-run on the next

Also check that CMake does not re-run if nothing has changed.
Whenever feature support is added to a compiler, the CompileFeatures
test needs to be updated to set expected availability of features.
Add #error directives to ensure the test fails if expectations are
not set.

Fix the <lang>_non_features try_compile calls to work correctly when

Add an option to set the mtime of entries in a tarball so that one can

The CXX_STANDARD property validates the values allowed for it,
and '90' is not a valid value for it. However, the validation is only
done for languages enabled for the target, and as C_undefined has no
CXX files, that language is not enabled for it.

We require that the $<$<COMPILE_FEATURES:cxx_feature>:empty2> generates
a '1' when CXX11 is enabled. GNU 4.4 does not support cxx_nullptr, but
does support cxx_auto_type.
The purpose of that test is to cover the case where the genex
reports '1', and the feature is chosen to be present on all/most
supported compilers. GNU 4.4 does not support cxx_nullptr.
The change in commit 1f19ac4d (Features: Adjust cxx_variadic_templates
unit test for GNU < 4.7., 2015-01-11) pacified GNU 4.6, but leaves
SolarisStudio 12.4 complaining:
"cxx_variadic_templates.cpp", line 5: Error: Partial specialization for Interface<Is...> has identical arguments.
1 Error(s) detected.
Implement a preprocessor test for using the partial specialization
workaround needed by GNU 4.6.
SolarisStudio considers 'auto' to be a storage class specifier in
C++98 mode (as appropriate), and considers variables without a specified
type to be of type int. So, it treats
auto x = 3.14;
as
auto int x = 3.14;
which in C++98 mode is equivalent to
int x = 3.14;
and it does not fail to compile as expected.
Change the test to use a reference so that the type must be known.

This topic was merged to master prematurely, so remove it.
Commit v3.1.0-rc1~297^2~5 (cmTarget: Drop 'head' argument from
GetSourceFiles, 2014-07-10) exposed a dormant bug in source file computation,
causing the test case to regress. After that commit, the source file
computation and caching finds an existing container of source files. Prior to
that patch, the GetSourceFiles method was called with either a null pointer
for the head cmTarget, or it was called with the this pointer. The
processSources method is eventually called, which normalizes the difference
between the null pointer and the this pointer for the head target. However,
the cache key depends on the actual pre-normalized pointer. The change in
that commit caused the entry to be found in the cache where it was not before,
which resulted in incorrect behavior.
Prior to that commit, the test case also fails if the GetSourceFiles overload
taking a vector<cmSourceFile*> is changed to normalize the head target at
the beginning of the method:
cmTarget const* head = head_ ? head_ : this;
Such a construct was correctly used in other locations where similar caching
was in place, before being removed in commit v3.1.0-rc1~310^2~25 (cmTarget:
Remove 'head' argument from GetLinkInformation, 2014-06-12), but is not
neccessary anymore.
Commit v3.1.0-rc1~674^2~2 (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05) introduced the caching, but fails the test case
for an unrelated reason. That unrelated error was introduced in
commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18) and fixed in
commit v3.1.0-rc1~561^2~1 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13).
All commits which fail the test case in the testable way do so when such a
cached version of the source files is found and returned at generate
time. In the test case, the cached content is populated at configure-time
through the use of the deprecated LOCATION property with CMP0026 OLD. The
cached content is an empty container for the bar target in the test case,
because its source file 'foo.cpp.o' is not known until generate-time. That
means that no source files are available to compute the link language and
the reported error is issued.
The actual problem is that the SourceFilesMap should be cleared after
configure time by cmTarget::ClearLinkMaps. Clear it there now.

Notes:
VS2015 and above are the only MSVC versions to support cxx_final, so remove
usages from the tests, and instead only test for cxx_override.
VS2012 and above to conform to cxx_decltype_incomplete_return_types
proposal, but without support for auto return types the dcl.type.simple
example in the proposal doesn't compile.
VS2013 and above to conform to the updated cxx_contextual_conversions proposal,
but VS2010 and above pass the test.
Compilers such as MSVC have no explicit flags to enable C++11 mode,
it just is always on. So only run the link tests with compilers that require
a flag to specify the language version.
Previously we expanded HAVE_FINAL to determine what the copied_file number
would be, but when we don't have cxx_final than HAVE_FINAL is not defined.
What we really want is to use expected_result.
For complex*, CustomCommand and OutDir tests, non-ascii paths
are avoided in test code by using relative paths, and setting
the working when running the test. This also avoids the
need to internationalize the test code.
For RunCMake.GeneratorExpression, use a UTF-8 encoding in
file(STRINGS) to retrieve the compiled absolute path correctly.
Because not all compilers under test support the existing 'activation
features', add another test to ensure that compilers which support
both static_assert and nullptr behave as expected in this test.
The purpose of the feature listing in these tests is to make other
features from the same feature set (eg "C++11 features") available.
The compilers under test until now have supported these 'activation
features', but MSVC does not. Use the cxx_static_assert feature
instead to activate the feature set.
The tests below test the presence of both cxx_final and cxx_override,
only one of which is supported by MSVC. The test is in part intended
to verify that the COMPILE_FEATURES genex supports multiple arguments
and allows users to define names for groups of features (Clang already
calls cxx_final and cxx_override 'override control' as a group). Keep
the test, and allow the expectation to be set as appropriate.
Expect tests to specify stderr content if it is present.
Fix the CMP0019 test, which has only been testing the WARN status
until now. Specify in the CommandLine and FPHSA tests that content
is at least one character.
Set policies in the Language and CheckModules tests, which have empty
test output, modulo unrelated policies on some platforms.

When install(EXPORT) is given an absolute destination we cannot compute
the install prefix relative to the installed export file location.
Previously we disallowed installation of targets in such exports with a
relative destination, but did not enforce this for target property
values besides the location of the main target file. This could lead to
broken installations when the EXPORT is installed to an absolute path
but usage requirements are specified relative to the install prefix.
Since an EXPORT installed to an absolute destination cannot be relocated
we can just hard-code the value of CMAKE_INSTALL_PREFIX as the base for
relative paths. This will allow absolute install(EXPORT) destinations
to work with relative destinations for targets and usage requirements.
Extend the ExportImport test with a case covering this behavior.
We use cmGlobalGenerator::GetDirectoryContent to avoid repeating
directory listings. However, GetDirectoryContent loads content from
disk at most once. This breaks find_library calls that occur when disk
content has changed since preceding find_library calls.
Teach cmGlobalGenerator::GetDirectoryContent to save the directory
modification time when content is loaded and re-load content if it
changes.
Create a RunCMake.find_library test with a case covering this.
Extend the BuildDepends test with a case covering multiple custom
command outputs with the second one consumed by another rule. With the
old "multiple output pair" infrastructure used in the Makefile and Xcode
generators this did not work. Now that it is fixed, test the case
explicitly.
If this option is enabled, the test step is created with the
EXCLUDE_FROM_MAIN option, and if TEST_BEFORE_INSTALL is enabled, the
install step does not depend on the test step.
This means that the test step is never executed, unless the test target
is explicitly created by calling ExternalProject_Add_StepTarget, or by
passing it with the STEP_TARGETS option, or with the EP_STEP_TARGETS
directory property.
Copy CMAKE_EXE_LINKER_FLAGS into the test project generated by
try_compile, just like we already copy CMAKE_<LANG>_FLAGS.
Add CMake Policy CMP0056 to activate this behavior in a compatible way,
but do not warn by default when the policy is not set since it will
affect all try_compile calls.
Extend the RunCMake.try_compile test with a case covering this behavior
for each policy setting.
Provide options to fail without blocking or to block up to a timeout.
Provide options to specify the scope containing the lock so it can be
released automatically at the end of a function, file, or process.
Extend the RunCMake.file test with cases covering the file(LOCK) command
usage and error cases.
Add a VS_DEPLOYMENT_LOCATION source file property to specify where to
put files that are part of the package. For example:
set_property(SOURCE ${ASSET_FILES} PROPERTY VS_DEPLOYMENT_LOCATION "assets")
Without this, sources marked with VS_DEPLOYMENT_CONTENT cannot be
located properly.
Create properties VS_SHADER_ENTRYPOINT and VS_SHADER_MODEL. Without
these many .hlsl source files may not be possible to use. Extend the
VSWinStorePhone test project to cover them.
8a75c7ef Help: Document the export limitation of INTERFACE_SOURCES.
e1348056 Export: Disallow export of targets with INTERFACE_SOURCES
bb5905bb cmTarget: Don't allow relative paths in INTERFACE_SOURCES
This can be allowed in the next release, but it needs to have some
features present and tested such as
* Ensuring that relative paths do not appear in the generated property.
* Ensuring that paths to the source or build directories do not appear.
* Generating a check in the file for CMake 3.1 or later so that the
resulting property will be consumed.
* Ensuring that any referenced targets are part of an export set and
generating a check for them.
* INSTALL_INTERFACE and BUILD_INTERFACE content.
All of these checks are already done for INTERFACE_INCLUDE_DIRECTORIES,
but it is too late to add them for INTERFACE_SOURCES for CMake 3.1.
As the checks introduce some new error conditions, it is better to
disallow exporting fully for this case and introduce proper error
conditions later instead of policies.
Follow the pattern of checks that are made for INTERFACE_INCLUDE_DIRECTORIES.
Existence is already checked by cmSourceFile::GetFullPath. Add a check
to disallow relative paths in source directories. Otherwise code such as
target_sources(lib1 INTERFACE foo.cpp)
would fail if consumed by a target in a different directory.
Unlike the INTERFACE_INCLUDE_DIRECTORIES behavior, we don't care whether
the entry comes from an IMPORTED target or not. In the include directories
case, the directory for a non-imported target might not exist yet but
might be created. In the sources case, a file which does not yet
exist in the filesystem must be explicitly marked with the GENERATED
property.
Adjust existing tests and add a new test for the error.
Extract a new method to encapsulate the requirements of evaluating
dependent-expressions, namely, propagation of the
EvaluateForBuildsystem setting, which is missing from the
getLinkedTargetsContent implementation.
Commit v3.1.0-rc1~688^2 (Genex: Only evaluate TARGET_OBJECTS to determine
target sources., 2014-03-20) introduced an error case for use of
TARGET_OBJECTS outside of the context of generating the buildsystem,
as the path to object files may be dependent on buildsystem
variables (See bug #15226).
Commit v3.1.0-rc1~314^2 (Allow INTERFACE_SOURCES to specify
$<TARGET_OBJECTS> (#14970), 2014-07-09) made it possible to
propagate such content to dependent targets.
While that commit propagated the EvaluateForBuildsystem setting
for the case of a TARGET_PROPERTY expression, as generated for
direct dependencies of a target in
cmTargetInternals::AddInterfaceEntries, it did not add propagation
for content from further transitive target dependencies, as determined
by getLinkedTargetsContent.
