 This will produce a large number of static archives (.a) here and

 can see a list of them in

 The configure script puts the app name as the CFBundleDisplayName
 property into the ios/Mobile/Info.plist file, and sets up some
 symbolic links that point to the LibreOffice core source and build
 directories (which typically will be the same, of course).
