TegraJPEG support for libfreenect2 ?

I got libfreenect2 successfully running on a NVIDIA Jetson nano.
However, when i do a cmake … -DCMAKE_INSTALL_PREFIX=$HOME/freenect2 it tells me “TegraJPEG = no”.
Does anybody know how to get that to “yes” on a Jetson nano and if it gives any speed improvement?

FindTegraJPEG.cmake file is too old , not support l4t 32.2
on jetson 32.2
no /etc/nv_tegra_release file
(TegraJPEG_INCLUDE_DIRS) jpeglib.h include file on /usr/src/nvidia/tegra_multimedia_api/include/libjpeg-8b
(TegraJPEG_LIBRARIES) libnvjpeg.so library on /usr/lib/aarch64-linux-gnu/tegra/libnvjpeg.so
