Make SwiftPM automatically search for static libs(*.a) inside project

Hello, there are no .c files inside swift project, but there are static libs(.a) inside the swift project and i dont want to pass "-Xlinker -L/path/to/lib" flag.
How to make SwiftPM automatically search for static libs(*.a) inside swift project without passing "-Xlinker -L/path/to/lib" flag?
Is it possible?
