java.lang.UnsatisfiedLinkError while trying to load opencv

I am trying to use opencv in a Scala application built using sbt and this is my build.sbt

name := "Marker"

version := "1.0"

scalaVersion := "2.11.8"

javaOptions in run += "-Djava.library.path=/home/priyatham/libs/opencv-3.1.0/build/lib"

And this the error I am getting when I sbt run

[error] (run-main-0) java.lang.UnsatisfiedLinkError: no opencv_java310 in java.library.path

What's wrong with the way I am modifying java.library.path

EDIT: I did put the opencv-310.jar in Marker/lib folder

Compiling with java -Djava.library.path="/home/priyatham/libs/opencv-3.1.0/build/lib" works though, but not with sbt run

EDITED:

Add fork in run := true. I think now it tries to run your code in same JVM so javaOptions is not applied.
