That is clearly caused by missing include files, and not a library path error.
You need to check that the missing files (phonon/videoplayer.h,
Phonon/MediaObject etc) are available in the SB2'ed development environment =
in the sysroot/rootstrap you are using. If they are, then it is probably matter
of adding proper -I flags for the compiler; but if those are missing
completely, you need to add them. How to do that depends on what kind of system
you are using as the rootstrap content, and not on SB2 or the host system.
