semanticdb-project-predicate-functions is a variable defined in `db.el'.
Its value is

nil

• This variable may be risky if used as a file-local variable.

Documentation:
List of predicates to try that indicate a directory belongs to a project.
This list is used when `semanticdb-persistent-path' contains the value
'project. If the predicate list is nil, then presume all paths are valid.

Project Management software (such as EDE and JDE) should add their own
predicates with `add-hook' to this variable, and semanticdb will save tag
caches in directories controlled by them.
