Qt5 create an exe file

I'm trying to create a Qt5 executable on Windows, when I built the project from QtCreator and went to the build folder and started the .exe I received a lot of missing library errors, and I fixed it using windeployqt:

>C:\Qt\5.15.2\msvc2019_64\bin\windeployqt.exe App.exe

Then I had another problem:

The application was unable to start correctly (0xc000007b).

And I simply solved it by installing Visual C++ Redistributable Packages for Visual Studio 2013. But now if I try to start it it gives me an error:

The code execution cannot continue because libwinpthread-1.dll was not found.

Does anyone know how to fix it? Thank you.

There's a description for this process (which is called deployment) in the Qt manual, e.g deployment with windeployqt, you might also look at the Qt Wiki for manual deployment.

BUT: It looks as though you mixed up something in you application: Visual C++ Redistributable Packages are needed in case you compile your application with Microsoft compilers. libwinpthread-1.dll is needed in case you compile your application with mingw compiler.

Make sure that you are using the same compiler/linker for all libraries, sources and the pre-built binaries from Qt.
