文章讲述了在CMake的FindGlog模块中，由于目标glog::glog已存在，导致添加错误。提供了解决方案：在添加glog::glogtarget之前检查其是否存在，若不存在则进行添加。

CMake Error at /usr/local/lib/cmake/Ceres/FindGlog.cmake:349 (add_library):
add_library cannot create imported target "glog::glog" because another
target with the same name already exists.

SOLUTION：在add glog::glog target之前判断一下是否target到glog::glog了，如果没有target到，再添加glog::glog target。在/usr/local/lib/cmake/Ceres下的FindGlog.cmake文件中的

# add glog::glog target
add_library(glog::glog INTERFACE IMPORTED)
target_include_directories(glog::glog INTERFACE ${GLOG_INCLUDE_DIRS})
target_link_libraries(glog::glog INTERFACE ${GLOG_LIBRARY})

修改为：

# add glog::glog target
if(NOT TARGET glog::glog)
    add_library(glog::glog INTERFACE IMPORTED)
    target_include_directories(glog::glog INTERFACE ${GLOG_INCLUDE_DIRS})
    target_link_libraries(glog::glog INTERFACE ${GLOG_LIBRARY})
endif()
