| # 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``. |
