Add an APPLY action to $<LIST:TRANSFORM> that evaluates an arbitrary <body>
once per selected element, with $<_0> bound to the element, so a list can be
mapped through any generator expression at generate time. Unlike the
configure-time list(TRANSFORM ... APPLY <function>) command, the genex form has
no side effects and returns the body's value directly, and a list-valued result
expands into multiple elements.
The body evaluates in its own binding scope, so nested APPLY actions can shadow
$<_0>, and context-sensitive state it observes (such as target dependencies)
still propagates to the enclosing expression. APPLY accepts the same
AT/FOR/REGEX selectors as the canned actions.
Issue: #27892
Introduce "binding operations": generator expressions that evaluate a <body>
once for each value they supply, with $<_0> expanding to that value. This is
the foundation the $<LIST:TRANSFORM,...,APPLY> action and the predicate
selectors build on, letting a <body> refer to the element being processed.
Using $<_0> outside a binding operation is reported as an error rather than
silently expanding to nothing.

Four per-format version descriptions in cmake-instrumentation.7.rst
still claimed the data version is always 1.0, contradicting both the
authoritative Data Version paragraph (which says 1.1) and the JSON
schemas (which accept minor versions 0 and 1).
Replace the hardcoded version claims with a reference to the Data
Version section, so these lines remain correct as future minor
versions are added without requiring additional doc updates.
Fixes: #27889
The overall `cmakeBuild` snippet is written only after the native build
tool returns, so interrupting `cmake --build` with Ctrl+C terminated CMake
before it was recorded and lost the build's delineation.
When instrumentation is active, install a scoped, async-signal-safe handler
(POSIX SIGINT; Windows CTRL_C/CTRL_BREAK) that just flags the interrupt. The
existing write then runs during unwind, records the interrupting signal in a
new `interruptSignal` field, skips the post-build index hook, and re-raises so
the exit status still reflects the signal.
The handler lives in its own translation unit, keeping the platform-divergent
signal code out of the main instrumentation implementation.

In commit b65930a7a7 (Fortran: Add Fortran_BUILDING_INTRINSIC_MODULES
for building intrinsics, 2025-01-09, v4.0.0-rc1~223^2) we only
implemented the property for the Makefile generators. Implement it
for the Ninja generators too.
Fixes: #26803
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).
Fixes: #27877.
Prior to this commit, ctest would sometimes use the current working directory
as its binary directory rather than honoring `binaryDir` from a configure
preset. This would occur when using ctest in dashboard client mode to perform
an initial configuration with a preset.
`ctest --source-dir=<dir> -T Configure -D CTEST_PRESET=<preset>`
An explicit `--build-dir` still takes precedence over the preset's `binaryDir`.
