Propagates variables set in enable_language() logic up variable scopes
so that the language can be used by targets in the ancestor directories.
Works through block() and function() scopes as well. The
add_subdirectory() call can be thought of as the effective call site for
enabling the language. The same holds for endblock() and the actual
function call.
Adds a policy CMP0220 to control this behavior. As the language is
"enabled" at each ancestor scope, the policy is checked. If OLD, the
language is not enabled at this scope and the ones above.

Introduce `CMD_STRICT` to act as a parent for warnings about allowed but
disrecommended usage. Introduce a warning that discourages use of
non-target directives (which modify the build environment for the entire
[sub]tree). Add notes to the official documentation recommending use of
target-specific alternatives. This has been accepted wisdom for quite
some time, but only some of the affected commands made any mention of
this in the documentation.
File sets have evolved to be more ubiquitous throughout a CMake build,
outside the scope of simply the target_sources command. Move general
information to the `cmake-buildsystem(7)` manual and keep only
reference information specific to the syntax of target_sources in its
command page. Sprinkle some more cross-references to the new location.

The ctest(1) command line allows repeating -L/-LE to form an AND
filter over test labels, but the ctest_test() and ctest_memcheck()
scripting commands accepted only a single INCLUDE_LABEL/EXCLUDE_LABEL
value, so a dashboard script could not express that filter.
The label-matching engine already stores the include/exclude
expressions as vectors and applies them with AND semantics; only the
command binding was single-value. Change both keywords to multi-value
(NonEmpty<vector<string>>) and hand the collected list straight to the
engine. ctest_memcheck() gains the same behavior for free, since it
inherits the option set.

Move documentation added by commit 45623dd5f6 (cmake_language: Add
PRINT_TARGETS operation, 2026-06-26) to the end of the signature list
to make room for more print signatures.
Issue: #27513
Recent changes to the `target_sources()` docs changed the `<items>`
placeholders to `<source>` or `<files>` (for `FILE_SET` commands),
but the documentation still used "items" frequently, and even
`<items>` once.
Change all mentions of "items" to use terms that match the
corresponding placeholders, for consistency.

The install({TARGETS, EXPORT}) versions of the command now accept ALIAS
targets. The behavior is identical to what would happen if the name of
the target that the ALIAS references were put instead. The
export(TARGETS) command also has the same support and behavior for ALIAS
targets now.

The add_dependencies command currently accepts ALIAS targets for
<target-dependencies> which resolve to the referenced target. This further
relaxes the command to accept an ALIAS <target> where the command will
add the dependencies to the target which the alias references.
Now that set_property and set_target_properties support ALIAS targets,
we need to extend support to all the target_* type commands that modify
target properties.
Relaxes target_compile_definitions, target_compile_features,
target_compile_options, target_include_directories,
target_link_directories, target_link_libraries, target_link_options,
target_precompile_headers, and target_sources to now accept ALIAS
targets. These commands set properties on the target which the alias
references.
Currently, getting properties from an ALIAS target retrieves the property
from the target which the alias references while setting properties results
in an error. This relaxes set_property and set_target_properties to
accept ALIAS targets and act on the referenced target, mirroring the get
behavior.
An error is raised when setting ALIAS_GLOBAL or ALIASED_TARGET on an ALIAS
target.
Closes: #19445
Add an --out-of-date option to ctest which runs only those tests with
recorded build dependencies whose timestamps are newer than the timestamp
at which the test last finished.
Fixes: #27614
Extend the test_prep/<test> and test_prep/all build targets, generated
from add_test(BUILD_DEPENDS) when CMAKE_TEST_BUILD_DEPENDS is enabled, to
the Makefile generators. Previously only the Ninja and FASTBuild
generators provided them.
Resolve each test's dependencies in a shared layer so all command-line
generators consume one result. cmTestGenerator now filters target
dependencies to build-system targets and records, for each file
dependency, the single target that produces it as a primary
custom-command output (cmGlobalGenerator::FindOutputOwningTarget). The
Makefile generators emit phony rules in CMakeFiles/Makefile2 depending on
<target>.dir/all, with top-level forwarding rules. Sharing the
resolution also stops Ninja and FASTBuild from emitting a dead test_prep
edge for a non-buildable (e.g. INTERFACE) BUILD_DEPENDS target.
On the Makefile generators a file dependency that no single target
produces, and a test whose name contains ':', cannot be expressed as a
recursive-make rule and are reported with a warning and skipped.

Add an existence check to the `if` command for diagnostic categories,
mirroring the check for policies. Aside from being desirable for
consistency's sake, this will make it easier for users to write logic to
manipulate diagnostics from newer versions of CMake that don't exist
today.
Exclude files and directories matching the given patterns while creating
an archive, using libarchive's matcher for parity with file(ARCHIVE_EXTRACT).

Omit archive entries matching the given patterns when extracting or
listing. May be combined with PATTERNS; on overlap the exclusion
takes precedence.
