When a built-in cache variable is set via `-D <var>=<value>` with no help text supplied, populate `HELPSTRING` from the built-in documentation table (sourced from `Help/variable/*.rst` and the per-language pattern manuals). Project-defined and unknown variables continue to receive the legacy "No help, variable specified on the command line." sentinel. The cache entry's type and value are left untouched: type stays `UNINITIALIZED` for bare `-D` and an explicit `-D <var>:TYPE=<value>` is honored as before. The `cmCacheManager::LoadCache` path is not modified, so reload of existing caches is a fixed point. Fixes: #27830

# Defines a placeholder-shaped built-in cache variable on the command

# line with no ``:TYPE=`` annotation. No exact-match entry exists for
|
|
# ``CMAKE_CXX_CLANG_TIDY`` in ``cmCacheDocumentationTable``;
|
|
# ``cmake::ProcessCacheArg`` therefore consults the pattern table
|
|
# (``cmCachePatternTable``), matches the ``CMAKE_<LANG>_CLANG_TIDY``
|
|
# pattern, and installs the pattern's Summary as the entry's HELPSTRING.
|
|
# Type and value are preserved verbatim. The project listfile itself
|
|
# does not ``set(...)`` the variable; the cache entry materializes
|
|
# solely through ``-D``.
