c++代码：#includestringpath="aaa.jpg";cv::Matmat=cv::imread(path.c_str());配置：set(OpenCV_DIR${CMAKE_SOURCE_DIR

find_packages搜索路径：设定一个project_DIR变量来指定路径，找到对应库的.cmake，例如：set(OpenCV_DIR/usr/share/OpenCV)多版本project：先用

set(OpenCV_DIR/xxxx/opencv_install/lib/cmake/opencv4)find_package(OpenCVREQUIRED)

linux系统：set(OpenCV_DIR/path/to/o

安装包双击下载的软件进行解压3.系统环境变量添加二.Qt搭建opencv开发环境创建一个新的Qt项目(Non-QtProject)打开创建好的项目中的CMakeLists.txt，添加如下代码#opencvset(OpenCV_DIR"C

生成zxing下载zxing，zxing-cpp-masterhttps://github.com/zxing-cpp/zxing-cppCmake生成项目，点Generate，把OpenCV_DIR修改了

cmake使用模块添加依赖很多情况下，项目倾向于直接使用第三方的cmake模块，以OpenCV为例，使用方式如下：set(OpenCV_DIR"${PROJECT_SOURCE_DIR}/${CMAKE_SOU

+python/c++调用简介1.项目环境2.TensorRT验证1.在tensorrtx-yolov5-v6.0\yolov5目录下新建build目录2.编写CMake.txt,根据自己目录更改2（OpenCV_DIR

分别如下：在CMakeLists.txt中配置在CMakeLists.txt中指明OpenCV_DIRset(OpenCV_DIR/home/User/opencv/build/)find_package

使用方法及可能出现的问题：单opencv版本时使用命令：find_package(OpenCV3.2REQUIRED)其默认是在user/local/目录下安装的opencv版本多opencv版本时使用命令：set(OpenCV_DIR

如果CMakeList文件中需要find_packageopencv4的情况，可以填写一下配置内容：...set(OpenCV_DIR/usr/lib/cmake/opencv4)#设置

文章目录CMake使用OpenCV添加OpenCV系统路径头文件尽情享用吧~CMake使用OpenCV添加OpenCV系统路径set(OpenCV_DIR"/share/OpenCV")find_package

opencvcmake使用实例set(OpenCV_DIR"D:/opencv/build"CACHEPATH"OPENCVdirectoryoverride"FORCE)#D:/opencv/build

报错CMakeErroratCMakeLists.txt:37(message):OpenCV>2.4.3notfound.解决办法CMakeLists.txt添加set(OpenCV_DIR/$

1.编译过程指定依赖包的路径1>cmake指定，在CMakeLists.txt文件中添加set(OpenCV_DIR"/usr/local/opencv3.4/share/OpenCV")find_package

1.准备好与vs版本对应的OpenCV，下载网址：https://opencv.org/release/2.opencv配置环境变量①.在环境变量中添加：OPENCV_DIR，它的值指向OpenCV安装目录

源码目录，使用如下命令更新：gitsubmoduleinitgitsubmoduleupdate此外还需要OpenCV，ITK以及ITKOpenCVBridge的支持，因此需要先对ITK进行编译，加入OPENCV_DIR

details/119994675所有步骤几乎一样，需要记录几点：1、CMakeList.txt修改cmake_minimum_required(VERSION2.6)project(yolov5)set(OpenCV_DIR"F

添加变量变量OpenCV_DIR，D:\OpenCV\Build\x64\vc101.以管理员身份运行命令控制符。

find_package(OpenCVREQUIRED)(2)使用指定版本时：#set(OpenCV_DIR"/home/liuxiangyue/其它/opencv-3.4.3/build")#Liucx

获取了棋盘格图像后就用opencv3自带的双目标定程序进行标定.stereo_calib.cpp文件如下,原始文件在Opencv2.49在Opencv_DIR/samples/cpp/stereo_calib.cppOpencv3.4

set（OpenCV_DIR/path/to/opencv/build）find_package(OpenCVR

点云拼接代码pcl编译问题我的CMakeLists（并不完整，没加eigen略了）cmake_minimum_required(VERSION2.8)set(OpenCV_DIR"/usr/local/

找到如下图所示路径，因为我的vs是2017版，所以打开vc15(2015版对应vc14)3.复制路径，新建系统环境变量，OPENCV_DIR4.讲改变量名添加到Path路径中，%OPENCV_DIR%\

Roskinetic中自带的OpenCV使用测试kinetic自带OpenCV-3.3.1头文件包括#include#include#includeCMakeLists.txt改动set(OpenCV_DIR

vsc++配置opencv配置总结环境变量OPENCV_DIR添加一个环境变量（可不添）OPENCV_DIRE:\work\openCV\opencv\buildPathPath中添加OPENCV的环境变量

cmake_minimum_required(VERSION2.8)project(imageBasics)#添加c++11标准支持set(CMAKE_CXX_FLAGS"-std=c++11")#寻找OpenCV库set(Opencv_DIR

1.CMakeLists.txt中指定OpenCV路径set(OPENCV_DIR/***/***/opencv-2.4.9)2.cmake工程编译安装mkdirbuildcdbuildcmake..make-j4sudomakeinstall3

1.多版本opencv相关CmakeList.txt文件设置set(OpenCV_DIR"/usr/local/opencv-3.4.1/share/OpenCV/")find_package(OpenCV3.4.1REQUIRED

cmakeversioncmake_minimum_required(VERSION2.8)#projectnameproject(test)#findopencv3OpenCVConfig.cmake#orset(OpenCV_DIR

空间，资源准备a.初始化b.克隆racecar源代码包，并编译(1)遇到问题：CouldNOTfinddriver_base_DIR(2)遇到问题：CouldNOTfindOpenCV(missing:OpenCV_DIR

第一、包含库，在项目属性的C/C++中的常规，在附加包含目录中增加$(OPENCV_DIR)\include第二、在连接器的常规选项中的，附加库目录增加$(OPENCV_DIR)\x86\vc12\staticlib

https://blog.csdn.net/mengchicmc/article/details/78458246添加到这个路径即可...\opencv\build（后面generate阶段会用到这个路径...\opencv\build\include，所以要把到build的路径丢给CMake）关于编译和配置的一些信息https://github.com/stevenlovegrove/Pango

方法1：让cmake找到opencv的OpenCVConfig.cmake文件，比如set(OpenCV_DIR"/usr/local/opencv3.4.2/share/OpenCV")#OpenCVConfig.cmake

相应在cmakelist.txt中改为set(OpenCV_DIR"/u

cmake_minimum_required(VERSION2.8)project(imageBasics)#添加c++11标准支持set(CMAKE_CXX_FLAGS"-std=c++11")#寻找OpenCV库set(OpenCV_DIR

configurecmakelistsfileofprojectcmake_minimum_required(VERSION3.1)#set(LIBS${OpenCV_LIBS}${EIGEN3_LIBS}${Pangolin_LIBRARIES}-lboost_system)#set(OpenCV_DIR

设置一个环境变量OPENCV_DIR（也可以不设置），指向D:\opencv\build。配置过程新建一个VS工程，本文起名为CV_Demo。右键点击解决方案

CvSVM存在多个版本OpenCV，指定OpenCV的编译路径修改CMakeLists.txt文件cmake_minimum_required(VERSION2.8)project(testApp)set(OpenCV_DIR

libopencv_xphoto.3.1.dylibReferencedfrom:（省略）Reason:imagenotfound推测可能是mac装了太多版本opencv，无法链接到正确lib库，所以手动指定下OpenCV_DIR

find_package(OpenCV3REQUIRED)set(OpenCV_DIR"D:/Code/SLAM/ORB_SLAM2/Thirdparty/opencv/sources/build/install

find_package(OpenCV3REQUIRED)set(OpenCV_DIR"D:/Code/SLAM/ORB_SLAM2/Thirdparty/opencv/sources/build/install

1、注意，使用的是opencv3,所以在cmakelists.txt加上（系统默认安装的是opencv2）set(OpenCV_DIR/usr/local/opencv3/share/OpenCV)2、
