For reference, Qt6's moc (the Qt project's current dev branch) supports
dependency generation:

    .../path/to/moc --output-dep-file ../function-with-attributes.h -o test.moc 

creates test.moc as generated source and test.moc.d containing the line

    test.moc: ../function-with-attributes.h

there's also --dep-file-path and --dep-file-rule-name to control the
output path and the rule name
