Development setup for Persee on Linux

I think I got that error when the sample program didn’t successfully load OpenNI2. I think it’s trying to locate the OpenNI2 libs from OPENNI2_REDIST environment variable path, but it might be something else. Run the sample through strace and see what dirs it’s using to find OpenNI2 / liborbbec.so and figure out if the sample program eventually manages to find them.
