System.DllNotFoundException: UnityInterface2

[ashokbugude]

Hi,

I am using Unity in Linux. When the run the project in Unity.I get below error

System.DllNotFoundException: UnityInterface2
at (wrapper managed-to-native) KinectWrapper:Init (bool,bool)
at KinectManager.Start () [0x00000] in /home/ashok/UnityPSHeadTracking/Assets/KinectScripts/KinectManager.cs:628
UnityEngine.Debug:LogError(Object)
KinectManager:Start() (at Assets/KinectScripts/KinectManager.cs:740)

Can I know from which path will Unity pick the dll file ?
