Add a new `PREDICATE` selector to `list(TRANSFORM)` that uses a
user-defined function or macro to decide which elements to transform.
The predicate callable receives each element value and an output
variable name. It must set the output variable to a truthy or falsy
value in PARENT_SCOPE; only elements for which the predicate returns
true are passed to the transform action.
Adds a shared PredicateEvaluator helper class used by both TRANSFORM
PREDICATE and (in a subsequent commit) FILTER PREDICATE.
Includes parser wiring, error and success tests covering all existing
actions (TOUPPER, TOLOWER, REPLACE, STRIP, GENEX_STRIP, APPEND,
PREPEND, APPLY) combined with the PREDICATE selector.

39a56136a3 Diagnostic: Add warn or error on absolute install paths
fd76089631 cmInstallFileSetGenerator: Only support per config Destination.
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !11882
Add `-Winstall-absolute-destination` diagnostic to warn or
error when an install command has an absolute destination.
This allow projects to enforce the best practice of not allowing
absolute install DESTINATIONS.
Add a new APPLY action to list(TRANSFORM) that invokes a user-defined
function or macro for each element of the list, enabling arbitrary
per-element transformations.
The callable receives the current element value and an output variable
name, and must set the output variable in PARENT_SCOPE to the
transformed value.
Includes documentation, release notes, and tests for both function
and macro callables, OUTPUT_VARIABLE, error cases, and selector
combinations (AT, FOR, REGEX).

The Pelles C compiler does not support ASM, and the `poasm` assembler
uses a distinct syntax. Add a dedicated language as we do for similar
cases from other vendors. Leave documentation commented out for now
because the PellesC toolchain support in general is not yet documented.

Also, correct the documentation added in commit 98f9874703 (cmake:
Add per-language link flags for all target types, 2025-12-17) by
placing the variables in the proper section of cmake-variables(7).

Consolidate the description of precedence during evaluation. Use xrefs
to improve syntax highlighting. Remove an outdated `versionadded`
directive for CMake 2.6.
Add a handful of helper roles that allow many more command-line option
references to be written without explicit targets. Specifically, what
used to be written ':option:`--foo[=bar] <program --foo>` can now be
written ':program-option:`--foo`'. This allows many such references to
be significantly shortened.
For now, supported programs are 'cmake', 'cpack'. 'ctest',
'cmake--build' and 'cmake--install', which should cover most cases, but
more can be trivially added. Additionally, this does not make a
concerted effort to replace all existing uses, as it is intended mainly
for use in future updates.
Two targets whose names differ only in a `.exe` suffix create a
conflict when adding target- and file-level dependencies for a custom
command. Add CMP0212 to provide compatibility with the old behavior.

In commit 51f39a0f32 (Help: Fix install(SBOM) argument typo, 2026-02-27,
v4.3.0-rc2~8^2) the typo was fixed in the wrong signature. Revert that
and fix the correct signature.
Create a stack state for managing diagnostics. This will eventually
replace some of the global state used for diagnostics, as well as
providing a mechanism to add additional diagnostics.
For now, this is only the stack manipulation with a bare minimum of
interface logic (in particular, the `block` and `include` commands).
Nothing actually looks at the diagnostic state yet, and the primary user
interface does not yet exist (although there are some references to it
already).
