Brad King d6a6024e9e Tests: Hide errors from `ldd --help` output check
If `--help` is not a valid option then it may print content to stderr,
so we need to capture that.

Brad King 13a6ff31be VS: Fix WINDOWS_EXPORT_ALL_SYMBOLS for object libraries
Teach Visual Studio generators to include object files from object
libraries in the list of objects whose symbols are to be exported.
The Makefile and Ninja generators already did this.  Update the
test to cover this case.

Brad King 1296a0eada Ninja: Fix inter-target order-only dependencies of custom commands
Custom command dependencies are followed for each target's source files
and add their transitive closure to the corresponding target.  This
means that when a custom command in one target has a dependency on a
custom command in another target, both will appear in the dependent
target's sources.  For the Makefile, VS IDE, and Xcode generators this
is not a problem because each target gets its own independent build
system that is evaluated in target dependency order.  By the time the
dependent target is built the custom command that belongs to one of its
dependencies will already have been brought up to date.

For the Ninja generator we need to generate a monolithic build system
covering all targets so we can have only one copy of a custom command.
This means that we need to reconcile the target-level ordering
dependencies from its appearance in multiple targets to include only the
least-dependent common set.  This is done by computing the set
intersection of the dependencies of all the targets containing a custom
command.  However, we previously included only the direct dependencies
so any target-level dependency not directly added to all targets into
which a custom command propagates was discarded.

Fix this by computing the transitive closure of dependencies for each
target and then intersecting those sets.  That will get the common set
of dependencies.  Also add a test to cover a case in which the
incorrectly dropped target ordering dependencies would fail.

Brad King d582c23a47 try_compile: Add policy CMP0066 to honor CMAKE_<LANG>_FLAGS_<CONFIG>
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`).
However, some projects may currently depend on this not being done,
so we need to activate the behavior using a policy.

This change was originally made by commit v3.6.0-rc1~160^2 (try_compile:
Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the
policy and so had to be reverted during the 3.6 release candidate cycle.

Fixes #16174.

Revert commit v3.6.0-rc1~160^2 (try_compile: Honor
CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11).  The behavior it
introduced can break projects that depend on the lack of such behavior.
We will have to introduce a policy or other mechanism to enable the
behavior in a compatible way.  Simply revert it for now.

See issue #16174.

Alex Turbov e63151ff54 cmake: Add an option to control what files needs to be traced
Even in relatively small projects using `--trace` (and `--trace-expand`)
may produce a lot of output.  When developing a custom module usually
one is interested in output of only a few particular modules.

Add a `--trace-source=<file>` option to enable tracing only a subset of
source files.  The final output would be only from requested modules,
ignoring anything else not matched to given filename(s).

Stephen Kelly 0a4af0735f cmake: Issue message independent of cmMakefile definition
The makefile is only used when called by the cmMessageCommand, so inline
the use of it there.  It otherwise creates an undesirable dependency on
cmMakefile for issuing messages in the cmake instance, a violation of
the Interface Segregation Principle.

 https://en.wikipedia.org/wiki/Interface_segregation_principle

This also makes it more explicit that the variable definitions only
affect the message() command.  If an AUTHOR_WARNING is issued for any
other reason, it is not affected.  To affect that, it is necessary to
set the cache variable instead of the regular variable.

This is an unfortunate interface quirk, but one which can't be fixed
easily now.

Daniel Scharrer 896ad251de Teach find_library and find_package to search lib32 paths (#11260)
Add a ``FIND_LIBRARY_USE_LIB32_PATHS`` global property analogous to the
``FIND_LIBRARY_USE_LIB64_PATHS`` property.  This helps find commands on
multilib systems that use ``lib32`` directories and either do not have
``lib`` symlinks or point ``lib`` to ``lib64``.

Brad King f500a784d0 Fix crash on $<TARGET_PROPERTY:...,LOCATION> genex (#16134)
Policy CMP0026 deprecated the LOCATION property, and we have long
provided a $<TARGET_FILE:...> generator expression.  However, if
a project tries to use $<TARGET_PROPERTY:...,LOCATION> we should
at least not crash.

The compatibility implementation of the LOCATION property uses
cmGlobalGenerator::CreateGenerationObjects to create the structures
needed to evaluate the property before generation starts.  The
implementation assumed that accessing the property could only be done
during configuration (via the typical get_property command use case).
The $<TARGET_PROPERTY:...,LOCATION> genex causes the LOCATION property
to be accessed during generation.  Calling CreateGenerationObjects
during generation blows away all the objects currently being used for
generation and is not safe.  Add a condition to call it only when
configuration is not finished.

Brad King d256ba078a try_compile: Optionally forward custom platform variables to test project
Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list

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.

Reiner Herrmann edcccde7d6 file: Sort GLOB results to make it deterministic (#14491)
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/).

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.

Brad King e1c7747253 Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first).  First
run `clang-format` with the config file:

    ---
    SortIncludes: false
    ...

Commit the result temporarily.  Then run `clang-format` again with:

    ---
    SortIncludes: true
    IncludeCategories:
      - Regex:    'sys/types.h'
        Priority: -1
    ...

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`:

    $ git ls-files -z -- \
        '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
      egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
      egrep -z -v '^Source/cm_sha2' |
      egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
      egrep -z -v '^Utilities/(KW|cm).*/' |
      egrep -z -v '^Tests/Module/GenerateExportHeader' |
      egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
      xargs -0 clang-format -i

This selects source files that do not come from a third-party.
