I have a problem with building my game

When I build my game for Windows, it starts by "Compiling Scripts" then it just stops building and a warning sign appears.

This is the following warning sign

Parent of RectTransform is being set with parent property. Consider using the SetParent method instead, with the worldPositionStays argument set to false. This will retain local orientation and scale rather than world orientation and scale, which can prevent common UI scaling issues.
UnityEngine.Transform:set_parent(Transform)
OVRUGUI:RiftPresentGUI(GameObject) (at Assets/OVR/Scripts/Util/OVRUGUI.cs:101)
OVRMainMenu:ShowRiftPresentGUI() (at Assets/OVR/Scripts/Util/OVRMainMenu.cs:974)
OVRMainMenu:Start() (at Assets/OVR/Scripts/Util/OVRMainMenu.cs:362)

And this is the script for "OVRUGUI"
