Eureka! Thank You for explaining. I think, my problem is located in the
definition of 'dependency' which seems to have a rather temporal meaning.
Let me repeat in my own words what You have said: If foo.cpp includes foo.h,
QBS detects a *dependency* between them through its built-in cpp-scanner.
Dependency means: if foo.h is generated by a rule, QBS ensures, that foo.h
is generated *before* foo.cpp is compiled. It does *not* add the output
folder of foo.h to the includePath of foo.cpp. The latter is what I have
expected and where the confusion comes from.

Is this correct?
