```



STEPS TO REPRODUCE
1. Install clang and libcxx.
2. Build kdeconnect with CXXFLAGS="-O2 -pipe -stdlib=c++" using CXX=clang++

OBSERVED RESULT

Build failure:
```
/var/tmp/portage/kde-misc/kdeconnect-22.08.1/work/kdeconnect-kde-22.08.1/core/backends/bluetooth/bluetoothdevicelink.cpp:95:12: error: chosen constructor is explicit in copy-initialization
    return {}; // TODO Not sure what to do here. For LanDeviceLink we use the SSL connection's certificate, but we don't hav
```

EXPECTED RESULT

Successful build.
