Error launching rtabmap

[kullboys]

Hello everyone
I cmake and make successfully without no errors, but when I was launching the app on Ubuntu 16.04 the following error shows up:
rtabmap: error while loading shared libraries: libfreenect2.so.0.2: cannot open shared object file: No such file or directory
Any ideas why?
Thanks.

Is libfreenect2.so installed in common /usr/local/lib ? If not, you will have to add the directory containing libfreenect2.so.0.2 to LD_LIBRARY_PATH environment variable.

cheers,
Mathieu
