| CACHE | |
| ----- | |
| .. versionadded:: 3.13 | |
| Operator to read cache variables. | |
| Use the syntax ``$CACHE{VAR}`` to read cache entry ``VAR``. | |
| See the :ref:`cmake-language(7) variables <CMake Language Variables>` | |
| documentation for more complete documentation of the interaction of | |
| normal variables and cache entries. | |
| When evaluating :ref:`Variable References` of the form ``${VAR}``, | |
| CMake first searches for a normal variable with that name, and if not | |
| found CMake will search for a cache entry with that name. | |
| The ``$CACHE{VAR}`` syntax can be used to do direct cache lookup and | |
| ignore any existing normal variable. | |
| See the :command:`set` and :command:`unset` commands to see how to | |
| write or remove cache variables. | |
