出现这个错误的原因是ecl升级了。造成了cmake版本比配。、

打开gazebo.repos,修改如下部分：


ecl_lite:


type: git


url: https://github.com/stonier/ecl_lite


version: release/0.61-indigo-kinetic


ecl_navigation:


type: git


url: https://github.com/stonier/ecl_navigation


version: devel


ecl_tools:


type: git


url: https://github.com/stonier/ecl_tools


version: release/0.61-indigo-kinetic 

(将ecl_core、 ecl_lite 和ecl_tools 的版本号（version）改成： release/0.61-indigo-kinetic）
