Hi Sid, thanks for the hint but see, i do have portaudio, not sure why cmake can't see it. Have tried both:

portaudio19-dev  and  libportaudio-dev

I have seen that problem many times with cmake. It can be quite a trial at times.

Run ccmake and manually set the portaudio options, then run cmake again.
Regards
Sid.
