Multiple executable targets sharing common code. Can they be packed into one project?

[parsifal]

Why so complicated?
Haven't your heard of a library?
Thats is what they are for!

Hello high_flyer! Yes, I indeed have, but:

I was thinking that maybe creating a shared dynamic library that holds the common code would be a nice approach, but I have yet to locate a thorough "From A-Z" example demonstrating this approach. And my own attempts with the help of only the Qt documentation proved inadequate.

Could you provide me with a small example please?
