ROS自带的OpenCV库和自己安装版本冲突问题现象及解决方法

1. 问题现象

1.1 编译过程警告

warning: lipopencv_improc.so.406, needed by /usr/local/lib/libopencv_xfeatures2d.so.4.6.0, 
may conflict with libopencv_imgproc.so.4.2

1.2 程序运行报错

terminate called after throwing an instance of 'cv::Exception'
error:(-4:Insufficient memory) Failed to locate 142099092348209 bytes in function 'OutOfMemoryError'
REQUIRED process has died!

2. 分析问题原因

根据编译过程提示是opencv版本冲突问题，仅以警告形式出现，程序可以编译通
