【CmakeLists】规范编写CmakeLits文件，以查找链接ZMQ与OpenCV库为例

本文主要是介绍【CmakeLists】规范编写CmakeLits文件，以查找链接ZMQ与OpenCV库为例，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

配置和生成项目时，CMake将尝试查找和链接ZeroMQ和OpenCV库。如果找到，它将输出相关信息并配置项目以使用这两个库。如果未找到任一库，它将产生致命错误消息并停止配置过程。

cmake_minimum_required(VERSION 3.0)
project(YourProjectName)# 查找 ZeroMQ 库
find_package(ZMQ REQUIRED)# 查找 OpenCV 库
find_package(OpenCV REQUIRED)if(ZMQ_FOUND AND OpenCV_FOUND)message(STATUS "ZeroMQ found (version ${ZMQ_VERSION}).")message(STATUS "OpenCV found (version ${OpenCV_VERSION}).")# 包含 ZeroMQ 头文件和 OpenCV 头文件include_directories(${ZMQ_INCLUDE_DIRS}${OpenCV_INCLUDE_DIRS})# 添加可执行文件，并链接 ZeroMQ 和 OpenCV 库add_executable(your_executable_name your_source_files.cpp)target_link_libraries(your_executable_name ${ZMQ_LIBRARIES} ${OpenCV_LIBS})else()if(NOT ZMQ_FOUND)message(FATAL_ERROR "ZeroMQ not found. Please install ZeroMQ and try again.")endif()if(NOT OpenCV_FOUND)message(FATAL_ERROR "OpenCV not found. Please install OpenCV and try again.")endif()
endif()
