How to connect Risip in Qt

How do you connect such libraries with the help of the compiler?

Download (or build) a version of the library that is compatible with your compiler.
Add the library to your project: https://doc.qt.io/qt-5/qmake-project-files.html#declaring-other-libraries
#include the library headers in your own code and call the library functions
Build your code

But PJSIP does not have dll and lib files.

Hi
You are supposed to produce the DLL and lib files your self by closely following
https://trac.pjsip.org/repos/wiki/Getting-Started/Windows

@mrjj is right. As I said in my previous post:

build a version of the library that is compatible with your compiler.

Here, "build" means use your compiler to create .dll/.lib files from the library's source code.

There is described an option for Visual Studio. But how to do it in Qt?

@Mikeeeeee Since you're using MSVC++ compiler (from Visual Studio) build the lib using the description for Visual Studio.

But is it possible to compile this dll into Qt? I have MSVC2019, but I never used it. How can I build a Dll in MSVC2019 (I created a library project)?

You don't compile a dll "into Qt". You simply compile it and then use in your app.

It is important to understand:

C++ is a language.
PJSIP is a C++ library.
Qt is a C++ library (mostly).
Qt Creator is an IDE.
Visual Studio is an IDE.
Microsoft Visual C++ is a compiler.

You use an IDE to write code and build applications/libraries. You need to tell your IDE which compiler to use.

You can use Visual Studio to write C++ applications that link to the Qt and PJSIP libraries.
You can use Qt Creator to write C++ applications that link to the Qt and PJSIP libraries.

How can I build a Dll in MSVC2019 (I created a library project)?

You must follow the instructions from PJSIP documentation. We do not know how to build PJSIP.
