Ubuntu下安装好OpenCV 设置opencv_DIR路径问题
用cmake运行了个测试程序 但是说opencv-dir路径不对 我找到了能用的在build文件夹里 怎么设置cmake让他以后调用有用的那个 希望能详细点回答我

Answer 1

CMakeLists.txt里面的内容如下：
cmake_minimum_required(VERSION 2.6)
PROJECT(Threshold)
FIND_PACKAGE(OpenCV REQUIRED )
INCLUDE_DIRECTORIES( ${OPENCV_INCLUDE_DIR} )
ADD_EXECUTABLE(Threshold MyCVProject.cpp)
TARGET_LINK_LIBRARIES(Threshold ${OpenCV_LIBS})

追问

opencv_DIR的默认路径怎么改

Answer 2

project(samples C CXX)

set(OpenCV_DIR /home/duanjiwei-ubantu/opencv-3.2.0/release)

option(BUILD_EXAMPLES "Build samples" ON)
