Got problem while building opencv accoding to link: Determining if the include file linux/videodev.h exists failed with the following output:Change Dir: /home/pi/opencv-3.1.0/build/CMakeFiles/CMakeTmpRun Build Command:/usr/bin/make cmTC_affcb/fast/usr/bin/make -f CMakeFiles/cmTC_affcb.dir/build.make CMakeFiles/cmTC_affcb.dir/buildmake[1]: Entering directory '/home/pi/opencv-3.1.0/build/CMakeFiles/CMakeTmp'Building C object CMakeFiles/cmTC_affcb.dir/CheckIncludeFile.c.o/usr/bin/cc    -fsigned-char -W -Wall -Werror=return-type -Werror=non-virtual-dtor -Werror=address -Werror=sequence-point -Wformat -Werror=format-security -Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes -Wundef -Winit-self -Wpointer-arith -Wshadow -Wno-narrowing -fdiagnostics-show-option -pthread -fomit-frame-pointer -ffunction-sections -fvisibility=hidden  -O3 -DNDEBUG   -o CMakeFiles/cmTC_affcb.dir/CheckIncludeFile.c.o   -c /home/pi/opencv-3.1.0/build/CMakeFiles/CMakeTmp/CheckIncludeFile.c/home/pi/opencv-3.1.0/build/CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:28: fatal error: linux/videodev.h: No such file or directory #include <linux/videodev.h>                            ^compilation terminated...........I just did cd linux in order to look file videodev.h is there, but system can't find such directory. File /usr/include/linux/videodev.h exist on my system. I suppose compiler is not able to find it. How to solve such problem?
CMake returns linux/videodev.h not exist while build opencv
make;opencv
