无法找到OpenCV库是由OpenCV的安装路径未正确配置引起的。通过确认OpenCV已正确安装,并设置正确的OpenCV_DIR环境变量,可以解决这个问题。

include_directories(/usr/local/include)来让库文件搜索以/usr/local/include为基础,即在main函数前写上#include “opencv/cv.h"即可 find_package(OpenCV 3 REQUIRED) 也就是只要找到了*.CMAKE,我们就能够给上图底部的几个变量赋路径 最后,记得将找到的库连接到我们的可执行文件上 ...
REQUIRED:可选参数,表示该外部库或框架是项目必需的。如果找不到指定的库或框架,CMake将生成错误信息并停止配置过程。 find_package(OpenCV REQUIRED) 上述代码表示OpenCV库是项目必需的,如果找不到该库,则配置过程将失败。 QUIET:可选参数,用于控制CMake在找不到指定库或框架时的输出。如果指定了该参数,CMake将不...
find_package(OpenCV REQUIRED) # 最常见用法 查找名为 OpenCV 的包,找不到就报错(并终止 cmake 进程,不再继续往下执行)。 find_package(OpenCV REQUIRED COMPONENTS core videoio) 查找名为 OpenCV 的包,找不到就报错,且必须具有 OpenCV::core 和OpenCV::videoio 这两个组件,如果没有这两个组件也会报错...

REQUIRED可选字段。表示一定要找到包,找不到的话就立即停掉整个cmake。而如果不指定REQUIRED则cmake会继续执行。 COMPONENTS:可选字段,表示查找的包中必须要找到的组件(components),如果有任何一个找不到就算失败,类似于REQUIRED,导致cmake停止执行。上面的例子中find_package( PCL REQUIRED COMPONENT common io )我们...
