问题1 :
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
GMOCK_LIBRARY (ADVANCED)linked by target "time_conversion_test" in directory /home/a/carto/src/cartographer_ros/cartographer_roslinked by target "configuration_files_test" in directory /home/a/carto/src/cartographer_ros/cartographer_roslinked by target "msg_conversion_test" in directory /home/a/carto/src/cartographer_ros/cartographer_roslinked by target "metrics_test" in directory /home/a/carto/src/cartographer_ros/cartographer_ros-- Configuring incomplete, errors occurred!

解决方案：
sudo apt install libgmock-dev
问题2 ：
代码运行时
[FATAL] [1713248900.406892955]: F0416 14:28:20.000000 7921 lua_parameter_dictionary.cc:83] Check failed: status == 0 (2 vs. 0) [string "include "map_builder.lua"..."]:35: attempt to index field 'pure_localization_trimmer' (a nil value)
在lua中pure_localization_trimmer的设置可能找不到，需要对比一下出处是否有定义或则定义内容更改等。经对比发现TRAJECTORY_BUILDER中对该内容进行注释。所以找不到。
TRAJECTORY_BUILDER = {trajectory_builder_2d = TRAJECTORY_BUILDER_2D,trajectory_builder_3d = TRAJECTORY_BUILDER_3D,-- pure_localization_trimmer = {-- max_submaps_to_keep = 3,-- },collate_fixed_frame = true,collate_landmarks = false,
}

编译过程找不到
