## Customizing the number of candidates retrieved for references in the Edit Mode

To prevent the retrieval of huge numbers of entities just to create candidates for the drop-down of
a reference during editing of an Entity, the number of candidates can be limited.

Set the `BUILD_MAX_EDIT_MODE_DROPDOWN_OPTIONS` build variable. -1 means no limit; every other number
is the limit for each query sent (The number of candidates can be at most twice this number).
