[traversaro]

Hello @robotology/everyone,

to simplify the finding of the repository of the ycm-cmake-modules package its repo has been renamed from https://github.com/robotology/ycm to https://github.com/robotology/ycm-cmake-modules . GitHub should redirect all the old links to issues and PRs, but make sure to update the links to the documentation website, that used to be http://robotology.github.io/ycm and now is http://robotology.github.io/ycm-cmake-modules, thanks.
