我在Linux下编译EasyPR项目时遇到的问题: 使用Ubuntu系统进行初次编译,报错如下: (check one with "x")

CMake Error at CMakeLists.txt:13 (find_package):
  Could not find a configuration file for package "OpenCV" that is compatible
  with requested version "3.1.0".

  The following configuration files were considered but not accepted:

    /usr/local/lib/cmake/opencv4/OpenCVConfig.cmake, version: 4.5.1

修改了13行的version为4.5.1,并修改/thirdpart/CMakeList.txt对应find_package为4.5.1,可以开始build,但后来报错信息如下:

猜测类似于 ‘CV_THRESH_OTSU’ was not declared in this scope的报错是由于openCV4.5.1版本不再使用CV_前缀,但其他报错不知道是什么原因,请问有什么办法可以不重新安装openCV的3.1.0版本而解决这个问题吗?

  • System: Ubuntu20.04.1 LTS

  • Compiler version/IDE: gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

  • CMake version: 3.16.3

  • **OpenCV version:**4.5.1-pre
