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.
