Expect cxx_variadic_templates to implement N2555.
N2555 is essentially a bugfix and predates most compiler releases which
aimed to experimentally support variadic templates.
This can be used to set the compiler features required by particular
targets. An error is issued at CMake time if the compiler does not
support the required feature. If a language dialect flag is required
by the features used, that will be added automatically.
Base the target_compile_features command on cmTargetPropCommandBase. This
gives us 'free' handling of IMPORTED, ALIAS, INTERFACE, non-compilable
and missing targets.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.
Use the same pattern of origin-debugging which is used for other
build properties.
Record the availability of this feature for GNU 4.8 on (UNIX AND
NOT APPLE) only. In the future, availability can be recorded for
earlier GNU, for other platforms and for other compilers. Initially
the affected configurations are as restricted as possible to allow
for easy testing while extending the features vector in only one
dimension.
The error message when using the set_property API directly is not
very good, but follow up commits will provide origin debugging of
the property and a target_compile_features command which will
provide a configure-time backtrace when possible.
This will allow decoupling the name of the test from the name and
location of the source file under test, which means one source
file can be used for multiple tests.
Rename the PARENT_SCOPE test in RunCMake.set to not use a keyword
of the if() command as a file name. As the filename is now used
with an if condition, this causes a conflict.
On OS X 10.9 the system libcurl has a different error message when
failing to connect:
Failed connect to :21; Connection refused

Extend the cmGeneratorExpressionDAGChecker with an interface
returning the name of the top target. Use that to determine
when there is a DAG violation, as required by the RunCMake.Languages
tests.
Disallow the use of config-specific source files with
the Visual Studio and Xcode generators. They don't have
any way to represent the condition currently.
Use the same common-config API in cmQtAutoGenerators. While
it accepts config-specific files, it doesn't have to support
multiple configurations yet.
Loop over the configs in cmTargetTraceDependencies

files.
Loop over the configs in cmComputeTargetDepends and compute the
object library dependencies for each config.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc. To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.
This commit may be reverted in the future if a solution to the
above difference is implemented.
Remove use of UseObjectLibraries from Makefile and Ninja generators. It
is not needed now because those generators use GetExternalObjects
which already contains the objects from object libraries.
The VS10 generator calls both the UseObjectLibraries and the GetExternalObjects
methods. Ensure that duplicates are not created by skipping objects
from object libraries in handling of GetExternalObjects.
Similarly, fix VS6, VS7 and Xcode object handling by skipping
external objects from OBJECT_LIBRARY usage as appropriate.
The error message in the BadSourceExpression1 test is now reported
by the generator expression evaluator, so it has different text.
Don't store a mapping of the directory to the ui file. The directory
will be a unique key, allowing only one ui file to be specified.
Use the source file name instead as the mapping key.
The rcc tool generates a cpp file with a symbol called qInitResources
or called qInitResources_${name}, if the name is passed. The
qInitResources symbol clashes if multiple qrc files are used in
one target.
Always pass the name to ensure that the symbol is unique. This is also
the behavior of the qtx_add_resource macros.
Since commit v2.8.12~327^2 (Qt4Macros: Allow specifying a TARGET
in invokations of macros., 2013-02-26), a parameters file is
populated with moc arguments at generate-time.
When the compile definitions or include directories change, the
parameters file is updated but moc is not re-run in response.
Fix that by making the moc invocation depend on the parameters file.

Rely on evaluation in cmCustomCommandGenerator for the generators.
When tracing target dependencies, depend on the union of dependencies
for all configurations.
Repeated "cmake . && ninja" calls were resulting in rebuilds every time.
Change the test so that it uses "file(WRITE" to generate a ".in" file and
then configure_file to "copy if different" that ".in" file to the final
generated source file.
Now, rebuilds will only occur if there are changes to the generated source
file on "cmake ." runs after the first one.
The FindKDE4 module (incorrectly) modifies CMAKE_MODULE_PATH on the
caller's behalf. This causes KDE4-installed find modules to be used by
the test instead of those in CMake. Teach the test to restore the
CMAKE_MODULE_PATH to its original value after each find_package call.
This ensures that the next find_package actually tests our module.
Use CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH
cache and environment variables to extend PKG_CONFIG_PATH before calling
pkg-config.
In each of the path in these variables it searches for lib/pkgconfig.
Then, depending on the system, it searches for
lib/${CMAKE_LIBRARY_ARCHITECTURE}/pkgconfig (debian) or for
lib64/pkgconfig (other 64 bit unixes). If any of these path is found,
it is appended to the PKG_CONFIG_PATH enviromnent variable.
Add two new arguments to the pkg_check_module and pkg_search_module
macro, NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH. The new signature
are therefore:
pkg_check_modules(<PREFIX> [REQUIRED] [QUIET]
[NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
<MODULE> [<MODULE>]*)
pkg_search_module(<PREFIX> [REQUIRED] [QUIET]
[NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
<MODULE> [<MODULE>]*)
By default, if CMAKE_MINIMUM_REQUIRED_VERSION is 3.1 or later (in
order to keep compatibility with the previous behavior), or if
PKG_CONFIG_USE_CMAKE_PREFIX_PATH is set, the CMAKE_PREFIX_PATH,
CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH cache and environment
variables will be added to pkgconfig search path.
The NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH arguments disable this
behavior for the cache variables and the environment variables,
respectively, similarly to the find_package() command.
Restore support for the undocumented <CONFIG>_LOCATION target property
removed by commit v3.0.0-rc1~175^2 (cmTarget: Remove support for
<CONFIG>_LOCATION property, 2013-12-30) as part of the CMP0026 OLD
behavior.
Visual Studio is handled as a special case for autogen depends. However,
the special handling works only for target dependencies, not file
dependencies output by a custom command.
Use a PRE_BUILD step only if all depends are targets.

Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
Since commit 71b14dcb (Utilities/Release: Do not upload doc staging
tarball, 2014-02-26) the prefix upload_release.cmake computes does not
match any files when used with -DVERSION=master as has been done for the
nightly binary builds. Since the version is not actually 'master'
anyway, change the nightly binary upload logic to explicitly pass the
destination directory. Do not pass any VERSION so the default is taken
and matches the binaries.

When running CMake from the build tree the CMAKE_ROOT is the
entire source tree. Fix the CMP0017 check to be specific to
the Modules/ directory under CMAKE_ROOT so that Tests/ does
not count. Fix the FindPackageTest modules to include FPHSA
by full path from CMAKE_ROOT so that they do not include the
local FPHSA which reports an error meant to test that CMP0017
works.
Add an undocumented CMake_TEST_EXTERNAL_CMAKE option to name an external
CMake 'bin' directory. Skip all main CMake binary builds and instead
configure the Tests directory to run using the external CMake provided.
This will provide a means to exercise the CMake test suite generating
for target platforms and compilers with which the CMake source does not
build. That will allow us to raise the level of C++ features required
of a compiler to build our source while retaining tests for generating
projects with older compiler tools.
In the ExportImport, Fortran, and MacRuntimePath tests the
CMAKE_TEST_MAKEPROGRAM variable is used to pass an explicit request for
a CMAKE_MAKE_PROGRAM value to be used when building the inner projects.
Rename these use cases to CMake_TEST_NESTED_MAKE_PROGRAM.
Follow the convention of naming variables related to the CMake build
itself as "CMake_" rather than "CMAKE_". While at it, consolidate the
code computing CMake_TEST_DEVENV to be more localized.
Drop the option to test with a different generator and make program than
was used to build. This was used only to test support for the Open
Watcom compiler which at one time could not build CMake. Instead we
will allow CMake to be configured to skip building binaries and just run
the test suite using an external CMake (in a future change).
For now leave the two option variables hard-coded to the old option
defaults until code can be updated to stop using them.
KWSys now has its own dashboard and test clients that run on all the
machines where we test CMake. We no longer need a test inside CMake to
test KWSys independently.
On OS X we pass -DCMAKE_POLICY_DEFAULT_CMP0025=NEW to all tests.
Once tests start using cmake_minimum_required(VERSION 3.0) then
CMake will warn that CMAKE_POLICY_DEFAULT_CMP0025 is unused.
These warnings are not part of the expected test output and can
cause such tests to fail. Pass --no-warn-unused-cli to each test
cmake invocation to tell it not to produce these warnings.
