I'm having issue with getting the sample projects to build for UWP on Unity. Everything works as expected while playing in the editor, but when I build, I get ~190 errors, a list of assembly reference missing errors. Starting with:
Assets\LeapMotion\Core\Scripts\Utils\LeapUnityExtensions.cs(12,7): error CS0246: The type or namespace name 'LeapInternal' could not be found (are you missing a using directive or an assembly reference?)
..... and continues with additional missing references for "Hand", "Finger", "Frame", "LeapTransform",.... etc etc.
This is a clean project, with Leap Motion assets package imported in > Select UWP as target > Build > no go.
