cmake找不到opencv解决

报错代码：

find_package(OpenCV REQUIRED)

解决方法1：主要问题在于库路径问题，应该在CMakeLists.txx中设置opencv路径指向build文件夹。

linux系统：

1. set (OpenCV_DIR /path/to/opencv/build)

2. find_package(OpenCV REQUIRED)

windows系统：

  

   

    

     

    
    

     

      set (OpenCV_DIR E:/opencv/opencv)
     
    
   

    

     

    
    

     

      #opencv
     
    
   

    

     

    
    

     

      find_package(OpenCV REQUIRED)
     
    
  
 

方法2，ok：

配一个环境变量：OPENCV_DIR 到bin目录的父目录

  

   

    

     

    
    

     

      set(OPENCV_DIR_HINT "")
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      if(WIN32)
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

          get_filename_component(OPENCV_DIR_PLATFORM $ENV{OPENCV_DIR} DIRECTORY)
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

          get_filename_component(OPENCV_DIR_HINT ${OPENCV_DIR_PLATFORM} DIRECTORY)
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      endif(WIN32)
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      set(OpenCV_STATIC OFF)
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      find_package(OpenCV REQUIRED HINTS ${OPENCV_DIR_HINT})
