Installing Skeltrack on Ubuntu

Skeltrack  is an Open Source skeletal tracker and tracks up to 7 joints currently: head shoulders, elbows, and hands .Openni and Microsoft SDK trackers are not open source, so this might provide developers a good platform to tweak the algorithm and parameters according to their application :)

If you encounter the following error

error while loading shared libraries: libfreenect.so.0.0: 

cannot open shared object file: No such file or directory

You need to refresh your ldconfig cache. The easiest way to do this is to create
 a file usr-local-libs.conf (or whatever name you wish) with the following lines:

/usr/local/lib64
/usr/local/lib

Switch to root account and move it to /etc/ld.so.conf.d/usr-local-libs.conf. 
Then update the ldconfig cache:

$ su root
$ mv ~/usr-local-libs.conf /etc/ld.so.conf.d/usr-local-libs.conf
$ /sbin/ldconfig -v
