编译cartographer时cmake .. -G Ninja时出错

Te amo X

Ubuntu版本18.04，ros版本melodic，按照csdn教程cartographer安装教程（超详细保姆级教程）
安装cartographer源码时进行到cmake .. -G Ninja时出错:报错内容如下:

CMake Error at CMakeLists.txt:32 (find_package): By not providing "Findabsl.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "absl", but CMake did not find one. Could not find a package configuration file provided by "absl" with any of the following names: abslConfig.cmake absl-config.cmake Add the installation prefix of "absl" to CMAKE_PREFIX_PATH or set "absl_DIR" to a directory containing one of the above files. If "absl" provides a separate development package or SDK, be sure it has been installed.
不知道怎么解决这个问题求助

@237279528 应该是absl没有装好，前面的步骤出错了。

@小鱼谢谢小鱼!刚刚这个解决了后面运行ninja命令时候又发生错误，提示ninja:build stooped:subcommand failed 这个应该咋解决呀

@237279528 这个错误我也没有遇到过，最好用一个干净的系统来装，前面步骤不要出错，不然后面出问题都不知道怎么整，看错误提示，因该是前面某一步出错了，仔细检查下。
