The timestamps are stored in the build graph for performance reasons 
(esp. for Windows). If you mess around with the contents of the build 
dir you must pass --check-timestamps to qbs.

Probably because the target file path in your output artifact is never 
generated. You said pbuilder will generate files in the source dir.
You could add a rule "html" -> "html-copy" that copies each HTML file 
into the build dir. Then a rule "html-copy" -> "html-cpp" runs pbuilder 
in the build dir where the cpp files will end up.

You can use a JavaScriptCommand for that in the "html-copy" -> 
"html-cpp" rule.
