qbs How to add @rpath to third party dependency?

[Marc_H]

We are using paho MQTT client and have paho.qbs file, which looks like this:

//paho.qbs
Product {
    qbs.installPrefix: project.installPrefix
    
   //abbreviated windows and linux groups

    Group {
        name: "Binaries (macOS)"
        condition: qbs.targetOS.contains("darwin")

        files: ["mac/lib/*"]

        qbs.install: true
        qbs.installDir: "bin"
    }

    Export {
        Depends { name: "cpp" }

        //abbreviated windows and linux properties

        Properties {
            condition: qbs.targetOS.contains("darwin")

            cpp.includePaths: ["mac/include"]
            cpp.dynamicLibraries: ["paho-mqtt3as", "paho-mqtt3cs"]
            cpp.libraryPaths: ["mac/lib"]
        }        
    }
}

Other libraries depend on this and everything compiles and links fine, but running an application with dependency on paho requires the working directory to be where the paho libs are located.

Output of otool:

//...
Load command 22
          cmd LC_LOAD_DYLIB
      cmdsize 48
         name libpaho-mqtt3as.1.dylib (offset 24)
   time stamp 2 Thu Jan  1 01:00:02 1970
      current version 1.3.8
compatibility version 1.0.0
//...

Is it possible to add @rpath to the load command?
Any help is appreciated. ✌🏼
