Use configure -list-features and pick something you definitely don't

lcdnumber ................ Widgets: Provides LCD-like digits.
and configure and build Qt with -no-feature-lcdnumber
That's probably not a good example, since the LCD number widget (the oldest
widget in Qt, aside from QWidget itself, because Qt had no font support yet
when this class was created) is fairly self-contained.
Anyway, there are a couple of suggestions in this thread to make the
application even smaller.
But it won't be tiny. That's just not in the cards.
Hi, also the choice of compiler can influence the size of the executable.
For example, on Windows I have a LOB Qt 5.15.2 Widgets-only app that I
build statically, with a configure that has a "-skip xxxx" for all
modules expect qtbase.
When using MinGW 8.1.0 the .exe size is 19151 kB and when using MSVC2019
it becomes 11616 kB, i.e. 40% smaller.
