CMakelists.txt找不到-lrt，也找不到-lpthread

Question

我要使用激光雷达，其SDK有两个文件夹，分别为"src"和includes。 src包含很少的CPP文件，而include包含头文件。现在，在我的main.cpp中，我必须导入一个头文件，其中包含使用Lidar所需的所有必要功能。

现在使用CMakelists.txt，我试图添加它们，但显示错误。

这是我的Cmakelists.txs

cmake_minimum_required(VERSION 2.8.3)
project(delta_lidar)

set(delta_lidar_SDK_PATH "./src/")

FILE(GLOB delta_lidar_SDK_SRC
        "${delta_lidar_SDK_PATH}/src/*.cpp"
        )

include_directories(
        ${delta_lidar_SDK_PATH}/include

add_executable(delta_lidar_node main.cpp ${delta_lidar_SDK_SRC})
