Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list
of custom variables to be forwarded to a `try_compile` test project.
This will be useful for platform information modules or toolchain files
to forward some platform-specific set of variables from the host project
(perhaps set in its cache) to the test project so that it can build the
same way.

Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify

This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.
Prevent accidental inter component dependency setting
since this is a breaking feature in situations where
another CPack module is already using the feature.
It should be enabled if desired since it can cause
issues when upgrading only one of the components
for e.g. configuration instead of all the components
at once.
This patch preserves backward compatibility of
deb package names with previous CMake versions
but similarly to CPack/RPM allows to change
package name format and supports DEB-DEFAULT
setting that produces proper Debian package names.

The purpose of the `update` step is to run an update on each build
(subject to `UPDATE_DISCONNECTED`). This is done for version-controlled
source directories. We should do it for a custom `UPDATE_COMMAND` too.
In particular, when `UPDATE_DISCONNECTED` is used we expect the
`skip-update` step to exist.
Even though the `file(GLOB)` documentation specifically warns against
using it to collect a list of source files, projects often do it anyway.
Since it uses `readdir()`, the list of files will be unsorted.
This list is often passed directly to add_executable / add_library.
Linking binaries with an unsorted list will make it unreproducible,
which means that the produced binary will differ depending on the
unpredictable `readdir()` order.
To solve those reproducibility issues in a lot of programs (which don't
explicitly `list(SORT)` the list manually), sort the resulting list of
the `file(GLOB)` command.
A more detailed rationale about reproducible builds is available
[here](https://reproducible-builds.org/).
Add a `CMAKE_NINJA_OUTPUT_PATH_PREFIX` variable. When it is set, CMake
generates a `build.ninja` file suitable for embedding into another ninja
project potentially generated by an alien generator.

Packagers may now set their own rpm package
file names or request that rpmbuild tool
chooses one for them. It also supports handing
of situations where one spec file may produce
multiple rpm packages.
Since CMake is written in C++98 any clang-format configuration must
set `Standard` to `Cpp03` so that `A<A<int> >` is not rewritten as
`A<A<int>>`. However, this will cause `U"foo"` to be rewritten as
`U "foo"`. Add markup to turn clang-format off in the one place
that the latter case occurs so that we do not need a separate
`.clang-format` config file for it.

Since commit v3.3.0-rc1~430^2 (Teach find_(library|file|path) to get
prefixes from PATH, 2015-02-18) we search in <prefix>/include and
<prefix>/lib directories for prefixes with bin directories in the PATH
environment variable. The motivation was to support MSYS, MinGW and
similar Windows platforms in their default environments automatically.
At the time this behavior was thought to be worthwhile in general.

Teach the `add_custom_command` and `add_custom_target' commands to
substitute argv0 with the crosscompiling emulator if it is a target with
the `CROSSCOMPILING_EMULATOR` property set.
Add a long comment inside a few braced initializer lists in order to
convince clang-format to break after the opening brace and format the
list without indenting every value past the opening brace.
A `$<TARGET_FILE:tgt>` generator expression does not cause insertion of
the emulator. Add a test covering this. While at it, extend the test
case to cover executables in a subdirectory. Also make the test
matching expressions more robust to support multiple add_test calls
without mixing them while matching.

Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:

d350308a Help: Improve AUTOMOC documentation layout
The test features multiple .cpp and .qrc files with the same name

Since commit v3.4.0-rc1~321^2~2 (Genex: Store a backtrace, not a pointer
to one, 2015-07-08) we treat cmListFileBacktrace instances as
lightweight values. This was true at the time only because the
backtrace information was kept in the cmState snapshot hierarchy.
However, that forced us to accumulate a lot of otherwise short-lived
snapshots just to have the backtrace fields available for reference by
cmListFileBacktrace instances. Recent refactoring made backtrace
instances independent of the snapshot hierarchy to avoid accumulating
short-lived snapshots. This came at the cost of making backtrace values
heavy again, leading to lots of string coying and slower execution.
Fix this by refactoring cmListFileBacktrace to provide value semantics
with efficient shared storage underneath. Teach cmMakefile to maintain
its call stack using an instance of cmListFileBacktrace. This approach
allows the current backtrace to be efficiently saved whenever it is
needed.
Also teach cmListFileBacktrace the notion of a file-level scope. This
is useful for messages about the whole file (e.g. during parsing) that
are not specific to any line within it. Push the CMakeLists.txt scope
for each directory and never pop it. This ensures that we always have
some context information and simplifies cmMakefile::IssueMessage.
Push/pop a file-level scope as each included file is processed. This
supersedes cmParseFileScope and improves diagnostic message context
information in a few places. Fix the corresponding test cases to expect
the improved output.
Create a <LANG>_CLANG_TIDY target property (initialized by a
CMAKE_<LANG>_CLANG_TIDY variable) to specify a clang-tidy command line
to be run along with the compiler.
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
The Custom-Symbolic-and-Byproduct case fails strangely on some
filesystems used by our nightly testing. Somehow on the first build the
`use-byproduct` output ends up with a timestamp older than
`gen-byproduct-stamp` even though the build log clearly shows them build
in the correct order (and must according to build system dependencies).
Work around this problem by adding an extra delay before building
`use-byproduct`.

Teach CTestCoverageCollectGCOV to honor the
CTEST_EXTRA_COVERAGE_GLOB variable. When this variable is set,
this module will glob for matching source files that were not
covered and include them in the resulting tar file.
The change in commit v3.5.0-rc1~198^2 (Ninja: Always re-run custom
commands that have symbolic dependencies, 2015-11-19) broke the
byproducts feature added by commit v3.2.0-rc1~340^2~2 (Add an option for
explicit BYPRODUCTS of custom commands, 2014-11-13) when SYMBOLIC
outputs also appear. This case occurs with AUTORCC-generated custom
targets because the output is SYMBOLIC (to always run) and the generated
file is a byproduct (for restat so dependents do not run unnecessarily).
The two use cases conflict because Ninja does not support per-output
restat. Favor restat whenever byproducts are present because it is
required for byproducts to work correctly. In use cases where we want
an always-run chain we simply will not be able to also use byproducts.
Refactoring in commit v3.5.0-rc1~272^2~11 (cmTarget: Implement ALIAS in
terms of name mapping, 2015-10-25) accidentally introduced logic that
assumes ALIAS targets always reference targets in their own directory.
Fix this and add a test case.
The configure-step fix is that `cmMakefile::FindTarget` should not consider
aliases. The purpose of this method is just to look up targets local to
a directory. Since ALIAS and normal targets share a namespace we know a
locally defined target will never collide with an ALIAS target anyway.
The method has 3 call sites, and this change is safe for all of them:
* `cmInstallCommand::HandleTargetsMode`: Rejects aliases before the call.
* `cmFLTKWrapUICommand::FinalPass`: Should never have considered aliases.
* `cmMakefile::FindTargetToUse`: Falls back to a global lookup anyway.
The generate-step fix is that `cmLocalGenerator::FindGeneratorTarget`
should not consider aliases. This method is the generate-step
equivalent to the above. The method has 2 call sites, and this change
is safe for both of them:
* `cmInstallTargetGenerator::Compute`: Never uses an alias target name.
* `cmLocalGenerator::FindGeneratorTargetToUse`: Falls back to global lookup.

executables with `-subsystem:console,5.02` to make them runnable on
Windows XP 64-bit. Ideally `cmake-gui` should instead be linked with
`-subsystem:windows,5.02` but with the Ninja and Makefile generators
CMake adds `-subsystem:windows` after our `-subsystem:console,5.02` flag
and the linker seems to interpret this combination as we need.
