UnityEditor.PlayerSettings does not contain a definition for targetGlesGraphics

[nzen]

I switched my project from Standalone to Android and now I get this error:

Assets/NGUI/Scripts/Editor/UIAtlasMaker.cs(120,36): error CS0117: `UnityEditor.PlayerSettings' does not contain a definition for `targetGlesGraphics'

1. #if UNITY_ANDROID || UNITY_IPHONE
2.                 if (PlayerSettings.targetGlesGraphics == TargetGlesGraphics.OpenGLES_1_x)
3.                 {
4.                         maxSize = Mathf.Min(maxSize, 1024);
5.                 }
6.                 else
7.                 {
8.                         maxSize = Mathf.Min(maxSize, NGUISettings.allow4096 ? 4096 : 2048);
9.                 }
10. #endif

It's also in UIPanelInspector line 185.

Commenting them out allows for export...
