SBT, how to add unmanaged JARs to IntelliJ?

Question

I have build.sbt file:

import sbt.Keys.libraryDependencies

lazy val scalatestVersion = "3.0.4"
lazy val scalaMockTestSupportVersion = "3.6.0"
lazy val typeSafeConfVersion = "1.3.2"
lazy val scalaLoggingVersion = "3.7.2"
lazy val logbackClassicVersion = "1.2.3"

lazy val commonSettings = Seq(
  organization := "com.stulsoft",
  version := "0.0.1",
  scalaVersion := "2.12.4",
  scalacOptions ++= Seq(
    "-feature",
    "-language:implicitConversions",
    "-language:postfixOps"),
  libraryDependencies ++= Seq(
    "com.typesafe.scala-logging" %% "scala-logging" % scalaLoggingVersion,
    "ch.qos.logback" % "logback-classic" % logbackClassicVersion,
    "com.typesafe" % "config" % typeSafeConfVersion,
    "org.scalatest" %% "scalatest" % scalatestVersion % "test",
    "org.scalamock" %% "scalamock-scalatest-support" % scalaMockTestSupportVersion % "test"
  )
)

unmanagedJars in Compile += file("lib/opencv-331.jar")

lazy val pimage = project.in(file("."))
  .settings(commonSettings)
  .settings(
    name := "pimage"
  )

parallelExecution in Test := true

It is working fine, if I use sbt run, but I cannot run from IntelliJ.

I receive error:

java.lang.UnsatisfiedLinkError: no opencv_java331 in java.library.path

I can add manually (File->Project Structure->Libraries->+ necessary dir). My question is: is it possible to specify build.sbt that it will automatically create IntelliJ project with specified library?

I would say try to: drag and drop the dependency into the /lib which should be in the root directory of your project, if it's not there create it.

Run commands: sbt reload sbt update

Lastly you could try something like: File -> Project Structure -> Modules -> then mark all the modules usually 1 to 3, delete them (don't worry won't delete your files) -> hit the green plus sign and select Import Module -> select root directory of your project and it should then refresh it

If none of these help, I'm out of ideas.
