My bad, it should have been Qt5::Widgets (not Qt but Qt5).

Fixing that gets us to a point where the compiler cannot find the header
<QPrinter>, which is a part of another Qt5 module: PrintSupport.

So we must add the component "PrintSupport" there:
FIND_PACKAGE( Qt5 REQUIRED COMPONENTS Core LinguistTools Widgets)
FIND_PACKAGE( Qt5 REQUIRED COMPONENTS Core LinguistTools PrintSupport 
Widgets)

And Qt5::PrintSupport there:
TARGET_LINK_LIBRARIES( qtbeads Qt::Widgets ...
TARGET_LINK_LIBRARIES( qtbeads Qt5::Widgets Qt5::PrintSupport ...

I think that's the build system sorted, even though the compilation 
still fails. Now you probably need to add some includes.
