How to attach .so and .h to Qt project [qmake][.pro]?

Question

Qt

Please tell me how to set the path to the dynamic libraries (.so) in the qmake-collector and connect them so that they work. And do you need the headers of this library? If yes, how to connect them correctly.

Answer 1

Headers are required if you want to use a lib in your program, which is obvious.
You need a lib, connects via 'LIBS +=' in the pro file. And yet it all googles well.
