It still crashes on gphoto init, and LD_PRELOAD still fixes it.

Even moving the libusb linking command to be the first link command that cmake 
sees does not seem to help.  Poking at it a bit, the highgui library from 
opencv links to libraw1394 and libusb, in that order. 

I tried to prevent linking to highgui, but libface uses it.

I also tried linking libusb in to kface and redeye_plugin before they link to 
opencv, but it does not seem to make any difference.

I suspect what is going on is that because libusb is already linked into 
highgui.so, even though libusb is on the list, it doesn't get re-linked. 

If I have time tomorrow I am going to compile opencv and change the link order 
there.
