Bug#726162: Replace libeigen2-dev by libeigen3-dev

[Maximiliano Curia <maxy@debian.org>]

¡Hola!

After applying your patch, the build ended successfully installing zero files. 
:) Nothing was compiled, nothing was installed, so the package was empty.

Could you check if something is missing?

Also, we would prefer if the patch gets eventually accepted upstream, that 
would mean (IMHO) to be able to use either eigen2 or eigen3, do you consider 
that possible?

Thanks,
