Reproduce this error by running:
==> cd /home/user/catkin_ws/build_isolated/cartographer_ros && /home/user/catkin_ws/install_isolated/env.sh cmake /home/user/catkin_ws/src/cartographer_ros/cartographer_ros -DCATKIN_DEVEL_PREFIX=/home/user/catkin_ws/devel_isolated/cartographer_ros -DCMAKE_INSTALL_PREFIX=/home/user/catkin_ws/install_isolated -G Ninja

ちなみに、catkin_ws内に、新たにファイルを追加した際にも同様のエラーが表示されます。
（『CMakeLists.txt』が存在するファイルを新たに追加した際に、エラーが出ます。）

解決策を知っている方がいましたら、教えていただけると幸いです。

Answer 1

困ったときは"error"だとか"fail"という文字列、もしくは色の違う強調部分を優先的にみると解決につながりやすいです。この場合、下の方のtime_conversion_test configuration_files_test msg_conversion_test``metrics_testがキーワードと思います。

锡城筱凯さんの読みでは、cartographer_rosがないためのエラーではないか、と投稿しています。

问题解决：

我尝试过使用sudo apt install google-mock安装GMOCK 但是它依旧提示上面的问题。但是我发现我使用 sudo apt install libgmock-dev，他安装了一些包，接下来catkin_make可以发现编译成功

sudo apt install google-mock
# 必要に応じて以下の対応
sudo apt install libgmock-dev

ROSもコンパイルも無縁な人間の回答ですので、念のため入念にバックアップをしてから対応ください。
