Cmake never links to _iphonesimulator libraries

Hi, Qt`s cmake scripts from Qt5.4.0/5.4/ios/lib/cmake/ never link to _iphonesimulator postfixed libraries, only to device ones. Most ios libraries I`ve worked with use a single fat binary for arm/x64, but Qt splits them into two separate libs for some reason. Also it looks like the cmake scripts are autogenerated, is the generator available somewhere? It should be quite easy to add the _iphonesimulator to library list in the generator.
