Hi Sascha,
I've actually found the same issue a while ago and made a curated list. I
added this to my install rules:
if(UNIX)
get_property(_qmake_location TARGET ${Qt5Core_QMAKE_EXECUTABLE}
PROPERTY IMPORT_LOCATION)
get_filename_component(_qmake_path "${_qmake_location}" DIRECTORY)
install(FILES "${_qmake_path}/../plugins/platforms/libqxcb.so"
DESTINATION "bin/plugins/platforms"
CONFIGURATIONS Release)
install(FILES "${_qmake_path}/../plugins/sqldrivers/libqsqlite.so"
DESTINATION "bin/plugins/sqldrivers"
CONFIGURATIONS Release)
install(FILES "${_qmake_path}/../plugins/iconengines/libqsvgicon.so"
DESTINATION "bin/plugins/iconengines"
CONFIGURATIONS Release)
install(FILES "${_qmake_path}/../lib/libQt5XcbQpa.so.5"
DESTINATION "bin"
CONFIGURATIONS Release)
install(FILES "${_qmake_path}/../lib/libQt5DBus.so.5"
DESTINATION "bin"
CONFIGURATIONS Release)
install(FILES "${_qmake_path}/../lib/libQt5Svg.so.5"
DESTINATION "bin"
CONFIGURATIONS Release)
endif()
Hope it helps!
