WARNING: Package "libg2o" does not follow the version conventions. It should not contain leading zeros (unless the number is 0).

I didn't understand where is the problem!

It's just a warning that the package does not follow the specified version patterns. It does not diverge far enough to break any tools in this case so you do not need to worry about it.

I had the same issue, and I think the mentioned version number is not really a problem. Can you use the library, if you ignore this warning? It didn't work for me, so I ended up building and installing g2o from source and then using it like a system dependency. I think the problem could be, that libg2o is not a catkin-package.
