How is that done?
I'm cc'ing Kevin on this reply for him to answer the APEX question. > @Hartmut: Do i need to do something extra to use VTune?

In order to integrate HPX with VTune you need to specify -DHPX_WITH_ITT_NOTIFY=On and -DAMPLIFIER_ROOT=<base directory of VTune> to cmake at configuration time. Please make sure that no APEX is enabled (-DHPX_WITH_APEX=Off) in this case.
