@bo-chong Seems like CMake is not finding the cartographer directory? Also the include line in the CMakeLists.txt is here https://github.com/cartographer-project/cartographer_ros/blob/c06879b63567a78ef92b7d1fa79453839e36ffec/cartographer_ros/CMakeLists.txt#L48 in line 48 and not 39. Did you made some changes to that file?
