4.26 Build Tools Failed on IOS even though disabled?

[Cambo-Au]

Hi,

Getting a strange issue where the Build Tools CS section is failing due to files missing for IOS, even though I have IOS disabled in the build platforms. The error below is referencing a missing icon for IOS, but even working around this leads to other errors in the IOS build. Is there a way to skip this?

Hi @Cambo-Au

This is an issue with the Engine build itself because the app is simply passing the arguments to AutomationTool and running it. Not sure if this is related to #30. I have recently compiled the Engine from master branch and it was success but I don't have iTunes installed (required for remote building according to the docs). Do you have iTunes installed? If you have, maybe the Engine is trying to build iOS under the hood.
