Source engine missing files on iOS packaging

I have compiled UE source 4.21.2 in order to try to fix a ios packaging problem but I stuck in another problem that I was not getting when using the release version

The error is this:

is missing several .a files but it is not requesting these files when I use the release binaries for 4.21.2 and also I wonder why these files do not get compiled on visual studio when building the project
I am missing something here to get those files compiled or removed from the iOS packaging process?

I’m facing the same issue, any clues? (I tried using unreal engine 4.22.3 and it does not happen there, sadly updating the engine is not an option right now)

sorry mate, updating was the only option
