Server output shouldn't become that big, even if you didn't had to wait for the entire output to be complete. Parsing something that's 20x larger than you need must come at a noticeable cost.

It can clearly do without them...

Looking at cmakemanager.cpp that probably means that you'd need to catch errors like this in ChooseCMakeInterfaceJob::successfulConnection() and make sure the failedConnection(int) slot is called on error.

Maybe you can simply do

        connect(job, &CMakeServerImportJob::result, this, [this, job](){
            if (job->error() == 0) {
                manager->integrateData(job->projectData(), job->project());
            } else {

Yes, though I don't really miss it.
