I installed dependencies accordding to the guide for ubuntu 16.04, and libusb, libopenni2 & OpenGL were installed well. But met some problem when make libfreenect2 .

result of make: nvidia@tegra-ubuntu:~/libfreenect2/build$ make [ 5%] Built target generate_resources_tool [ 69%] Built target freenect2 [ 89%] Built target freenect2-openni2 [ 92%] Linking CXX executable ../bin/Protonect ../lib/libfreenect2.so.0.2.0: undefined reference to 'drmAuthMagic' ../lib/libfreenect2.so.0.2.0: undefined reference to 'drmGetDeviceNameFromFd' ../lib/libfreenect2.so.0.2.0: undefined reference to 'drmFreeVersion' ../lib/libfreenect2.so.0.2.0: undefined reference to 'drmGetVersion' ../lib/libfreenect2.so.0.2.0: undefined reference to 'drmGetClient' ../lib/libfreenect2.so.0.2.0: undefined reference to 'drmGetMagic' collect2: error: ld returned 1 exit status examples/CMakeFiles/Protonect.dir/build.make:158: recipe for target 'bin/Protonect' failed make[2]: *** [bin/Protonect] Error 1 CMakeFiles/Makefile2:246: recipe for target 'examples/CMakeFiles/Protonect.dir/all' failed make[1]: *** [examples/CMakeFiles/Protonect.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2

Any idea for this?

../lib/libfreenect2.so.0.2.0: undefined reference to 'drmAuthMagic'

This means you enabled OpenCL or VAAPI, both of which aren't available on Jetson. So you want to disable them with cmake -DENABLE_OPENCL=OFF -DENABLE_VAAPI=OFF.
