-- C/C++: -- Built as dynamic libs?: YES -- C++ Compiler: /usr/bin/CC (ver 3.3.0)

I'm trying to build OpenCV with cmake on a FreeBSD 10 machine by following steps:

cd /usr/local/src
git clone https://github.com/Itseez/opencv.git
cd opencv && mkdir release && cd release

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

make

Then i get an error message:

[ 29%] Building CXX object modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_libv4l.cpp.o
/usr/local/src/opencvtest/modules/videoio/src/cap_libv4l.cpp:240:10: fatal error: 'asm/types.h' file not found
