lipo is not hard to use at all, however there should be no need to use
it when building Qt.

Fo example, configure line [1] initiates build for 4 architectures
(-arch armv7  -arch arm64  -arch i386  -arch x86_64)

See build log [2] for example (this is build configuration used for official
iOS packages).

All you need to change is to add -I and -L options to configure to specify
location of libpng headers and library. Make sure that configure summary
states "Using system libpng .... yes".
 

[1] configure -xplatform macx-ios-clang -no-sql-mysql -no-sql-psql -plugin-sql-sqlite -opensource -confirm-license -nomake tests -verbose -prefix /Users/qt/work/install -debug-and-release -static -no-icu -nomake examples
