[Interest] Struggling to build qt 5.9.9 for iOS

[maitai]

Ok, understood.

The thing is that I have built qt quite a number of times, for Raspbian, 
Windows 32 bits, Linux 32 bits and so on. I never had to use this 
option. From what you said I suppose qt 5.9.8 for iOS is not built with 
it, so why do I have to specify it for 5.9.9, all the rest (JDK, 
project) being equal ?
