Dear Maintainer,

The package fails to build inside some generated code:

In file included from /apper-0.9.2/obj-x86_64-linux-gnu/libapper/apper_automoc.cpp:4:0:
/apper-0.9.2/obj-x86_64-linux-gnu/libapper/moc_PkStrings.cpp:15:2: error: #error "This file was generated using the moc from 5.4.2. It [..] cannot be used with the include files from this version of Qt."
