The KWSys `SystemTools::SplitProgramFromArgs` implementation goes into
an infinite loop when the value is just " " (a space). Since the
"program path with unquoted spaces plus command-line arguments"
operation it is trying to provide is poorly defined (string parsing
should not depend on filesystem content), just stop using it.
Instead consider the main two use cases the old approach tried to handle:
* The value is the name or absolute path of a program with no quoting
or escaping, but also no command-line arguments. In this case we
can use the value as given with no parsing, and assume no arguments.
* The value is a command-line string containing the program name/path
plus arguments. In this case we now assume that the command line
is properly quoted or escaped.

flang is a Fortran compiler built on top of clang [1]. Because flang
shares a lot of commonalities with clang, the flang module piggybacks
off the clang module and overrides certain options.
Add flang to Fortran compiler auto find list.
Update flang preprocessor macros to differentiate from PGI.
Add Flang-FindBinUtils.

Create a `<LANG>_CPPCHECK` target property (initialized by a
`CMAKE_<LANG>_CPPCHECK` variable) to specify a `cppcheck` command line
to be run along with the compiler.
The change in commit v3.9.0~3^2 (Xcode: Add "outputPaths" to custom
command script build phase, 2017-07-13) was meant to support Xcode 9's
new build system. However, without matching "inputPaths", Xcode will
not re-run the build phase if its outputs have already been generated.
This broke the old Xcode build system too.
Revert the change for now so at least the old Xcode build system works.
Further investigation will be needed to add proper support for Xcode 9's
new build system.

This reverts commit v3.9.0-rc1~287^2 (macOS: Enable Hi-DPI support in
applications by default, 2017-04-08). It breaks iOS applications that
do not use their own `MACOSX_BUNDLE_INFO_PLIST` because `NSApplication`
is only for macOS apps. Until more complete support for iOS is added
to CMake (e.g. with a different default plist file) we must allow
our default plist file to work for both macOS and iOS.
Fixes: #17179
CMake can now compile as C++11 on all supported platforms. Check that
std::unique_ptr is available and fail early if missing. This will allow
us to use C++11 more broadly in CMake's implementation (previously it
was restricted to the serve mode implementation).

Disable the feature added by commit v3.9.0-rc1~71^2~2 (find_*: Add a new
PackageRoot search path group, 2017-05-03) and remove documentation
added by commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search
path group, 2017-05-03). Unfortunately the name `<pkg>_ROOT` may
already be set by projects for their own incompatible purposes. Disable
the behavior change for now to fix the regression for CMake 3.9. We can
restore it later with a policy.
In order to keep the implementation and tests working, add an
undocumented variable we can use in the tests to enable the behavior
before the policy is introduced.

CMake will soon require both C++11 and libuv to build. Neither of
these works on HP-UX, so unfortunately we need to drop support for
the platform until someone can get them working.
Issue: #17137
Add a new gtest_discover_tests function to GoogleTest.cmake,
implementing dynamic test discovery (i.e. tests are discovered by
actually running the test executable and asking for the list of
available tests, which is used to dynamically declare the tests) rather
than the source-parsing approach used by gtest_add_tests. Compared to
the source-parsing approach, this has the advantage of being robust
against users declaring tests in unusual ways, and much better support
for advanced features such as parameterized tests.
A unit test, modeled after the TEST_INCLUDE_DIR[S] test, is also
included. Note that the unit test does not actually require that Google
Test is available. The new functionality does not actually depend on
Google Test as such; it only requires that the test executable lists
tests in the expected format when invoked with --gtest_list_tests, which
the unit test can fake readily.
This lets AUTOMOC and AUTOUIC process GENERATED files which
used to be ignored before.
A new policy CMP0071 ensures that the old behavior of ignoring
GENERATED files is enabled when the CMake compatibility version
CMAKE_MINIMUM_REQUIRED is < 3.10.

Add a release note corresponding to the environmental regression fixed
by commit v3.9.0-rc6~15^2~1 (VS: Fix GenerateDebugInformation values for
v140 and v141 toolsets, 2017-06-27).
This is needed for Xcode 9's "New Build System", whose release notes
mention "that output must be declared as an explicit output by the
script which generates it" in reference to outputs of custom script
build phases.
