    Hello,

    I'm very new to QT software, I'm using QT 5.5.1 version. I have a .dll,.lib,.h files created from visual studio 2022. also, I have an existing QT project. i want to integrate this dll file with QT project. how can I achieve that, what are all the prerequisites for that? can anyone please tell me how to do that? 
    

    I tried to configure the compiler settings and added the cl.exe of MVSC 2022, still I'm getting this error "20:14:16: Configuration is faulty. Check the Issues view for details.
    Error while building/deploying project Serial_Port_Example (kit: Desktop Qt 5.5.1 MSVC2013 64bit)
    When executing step "Make" ". and it is giving this issue "Qt Creator needs a compiler setup to build. Configure a compiler in kit options. " How can i fix this issue.

    can anyone please help me to figure it out.

      Hi and welcome to devnet,

      You can forget about it. Binary compatibility started with VS2015.
      So either installed VS2013 or better yet update to a more recent version of Qt.
      Note that Qt 5 is reaching end of life.
