此问题与来自texasflood的答案:

This question is a duplicate of How to force c++ compiler use one of different installed package's versions, using CMake? but it is found by search engines so I add the answer from texasflood that I found to be working with CMake 2.8.12.2 and OpenCV 3.2.0 on Ubuntu 12.4:

只需更改find_package命令:

find_package(OpenCV REQUIRED PATHS "/usr/opencv-2.4.10")
