Nope, the same behavior.
ZM has OS detection block, I added there
set(CMAKE_REQUIRED_INCLUDES "/usr/include" "/usr/local/include") if 
system is BSD.

Now I have
-- Looking for libv4l1-videodev.h
-- Looking for libv4l1-videodev.h - found
-- Looking for linux/videodev2.h
-- Looking for linux/videodev2.h - found

and tests are passed/entire project is builded. Is hardcoded directory 
includes considered evil and I should find (read - ask here :)) ) better 
solution ?
