FTBFS with Qt 5.5: "cannot find -linput"

[Timo Jyrinki]

There seems to be some sort of new dependency, even though none were added in Qt 5.5's own build dependencies:
---
g++ -std=c++11 -Wl,-no-undefined -Wl,-Bsymbolic-functions -Wl,-z,relro -shared -o libqpa-ubuntumirclient.so backingstore.o clipboard.o glcontext.o input.o integration.o nativeinterface.o platformservices.o plugin.o screen.o theme.o window.o moc_clipboard.o moc_input.o moc_plugin.o moc_screen.o moc_window.o -lmirclient -lmircommon -lubuntu_application_api -lQt5PlatformSupport -lfontconfig -lfreetype -lgthread-2.0 -pthread -lglib-2.0 -linput -lxkbcommon -ludev -lmtdev -lEGL -lQt5Gui -lQt5Sensors -lQt5DBus -lQt5Core -lGLESv2 -lpthread
/usr/bin/ld: cannot find -linput
---

That is, qtubuntu and appmenu-qt5 should apparently have a build dependency on 'libinput-dev': https://launchpad.net/ubuntu/+source/libinput
