    As I already wrote - don't copy stuff around as it's wrong as it's missing things. Adjust your PATH var accordingly so that the Qt libs are properly found.

      You mean I should just add their absolute paths to the PATH var?

        Again: add the path to the Qt dlls to the PATH env var.

          Did it, nothing changed. (I restarted the project, of course)
          Same with deleting the associated environment vars

          @JonB
          It did. But it is not needed, I viewed it in the Dependency Walker

            Then you would get an error about missing dlls. You have some wrong dlls around somewhere.
            Delete all dlls you copied around, don't copy dlls around in your CMakeLists.txt or anywhere else during your build, use a clean build dir, set the env var accordingly and start it from the command line where you also started the dependency tools from...

              I did not copy around any DLLs, this is a clean build dir (CLion pre-config)
              I will try it.

              Added the env vars:

              Still get the Error messages that exactly these ones are missing...

                Added the env vars:

                You write that followed by a list of DLLs. What do you mean you did to what environment variable? Also you no longer list the Qt DLLs?

                Still get the Error messages that exactly these ones are missing...

                If you mean the 4 in that list are reported missing then you have not set your PATH correctly.

                I am lost.
