How to include sigar native libraries in sbt-native-packager Akka build?

I'm just curious if there is some nice way to do that with Akka packaging.

I found some examples here, but it was created for rpm build and I'm using these two plugins in my build.sbt:

.enablePlugins(AkkaAppPackaging)
  .enablePlugins(UniversalPlugin)

Actually I figured out one workaround by copying sigar libraries manually to directory where application starter script is generated.

There is also a need to set -Djava.library.path=./sigar to appropriate directory where sigar libraries are located, this can be set in build.sbt or changed later manually in generated scripts, by changing the JAVA_OPTS.

Here is what I did

  lazy val sigarJavaOpts = "-Djava.library.path=./sigar"

  libraryDependencies ++= Dependencies.sigar

  mappings in Universal ++= MappingsHelper directory getClass.getClassLoader.getResource("sigar").getFile

  bashScriptExtraDefines += s"""addJava "$sigarJavaOpts" """

  javaOptions in run += sigarJavaOpts

Note that I placed sigar files in my resources folder. You might also need to import from the following

import com.typesafe.sbt.SbtNativePackager.Universal
import com.typesafe.sbt.packager.MappingsHelper
import com.typesafe.sbt.packager.Keys.bashScriptExtraDefines

Also I do have a Dependencies object in which I have 

  val sigar = Seq(
    "org.fusesource" % "sigar" % "1.6.4"
  )
