cartographer编译失败
cartographer在编译的过程中，报错：multiple rules generate CMakeFiles/ ，提示编译pb.cc 文件冲突；把ninja换成1.8版本。报错消失。

Command failed, exiting.
解决：换ninja-1.8版
ubuntu 安装ninja
1.安装依赖re2c
root@ubuntu:~# apt-get install re2c
root@ubuntu:~# re2c --version
re2c 1.0.1
2.下载ninja （1.8版本，1.12版本也会报同样错误，其它版本自己试）
git clone https://github.com/ninja-build/ninja.git
3.编译ninja
cd ninja
./configure.py --bootstrap
4.安装ninja
cp ./ninja /usr/bin
ninja --version
5.打开控制台进入自己的项目
cd /home/sukai/cartographer_ws/src/cartographer/依次执行：
protoc cartographer/cloud/proto/*.proto --cpp_out=.
protoc cartographer/common/proto/*.proto --cpp_out=.
protoc cartographer/ground_truth/proto/*.proto --cpp_out=.
protoc cartographer/mapping/proto/*.proto --cpp_out=.
protoc cartographer/mapping/proto/pose_graph/*.proto --cpp_out=.
protoc cartographer/mapping/proto/scan_matching/*.proto --cpp_out=.
protoc cartographer/sensor/proto/*.proto --cpp_out=.
protoc cartographer/transform/proto/*.proto --cpp_out=.
protoc cartographer/kalman_filter/proto/*.proto --cpp_out=.然后
cd /home/sukai/cartographer_ws编译：
catkin_make_isolated --install --use-ninja
