Since qmake did not print anything before that "Usage:" line, it can be from 
this return in qmake/options.cpp:

                if(!handled) {
                    return Option::QMAKE_CMDLINE_SHOW_USAGE | 
Option::QMAKE_CMDLINE_ERROR;
                }

or from here:

            if(Option::mkfile::project_files.isEmpty()) {
                usage(argv[0]);
                return Option::QMAKE_CMDLINE_ERROR;
            }

The first one looks impossible to me: it would imply qmake_mode is still 
"generate nothing" and I don't see how that is possible. So it must be the 
second: the list of project files is empty. That means qmake somehow failed to 
see anything in the command-line.

Obviously that is not supposed to happen. Looks like the runtime completely 
failed to parse the GetCommandLineArgsW. Debugging is needed.
