Unbreak ui.rc lookup: use qrc file as source for executable, not static lib
Description
QRC files compiled into static libs need extra setup to have the resources registered. As the ui.rc file is not needed with the other usages of the static lib like the tests, just adding the qrc as source for the final executable is enough.
Question: it might make sense to rename labplot2.qrc to labplot2uirc.qrc perhaps, to specify the purpose some more?
