The `indexed_table_select_statement::actually_do_execute()` method
references `vector_search::vector_store_client::ann()`, but the
`vector_search` library, which provides its definition, is not linked
with the `cql3` library. This causes linker errors when other targets
are built, for example linking `comparable_bytes_test`, which links the
`types` library that in turn links `cql3` throws the following error :
```
...error: undefined symbol: vector_search::vector_store_client::ann...
```
Fix by adding `vector_search` to the private link libraries of `cql3`.
