理论上用最新的OpenCV4就行，当时最新的版本应该是4.5左右，但是官网的预编译包应该是不带FFmpeg的，如果需要视频处理的话，最好是自己编译OpenCV。
关于O0和gnu++11，可能你引了OpenCV的Debug库，也有可能是你的CMakeFiles里写了相应的SET，单纯的OpenCV库应该是不会自己往编译器加参数的。

然后Core的代码最好不要用release的2.5.0版本，用库里最新的。

哈喽，我又来了 T_T
因为我的需求只是处理图片，所以我就没有自己编译 OpenCV
我是直接使用的 Anime4KCPP_Android CMakeList.txt
OpenCV 也是直接在 opencv 的 Releases 下载的。
另外我使用了库里最新的 core 替换了 Anime4KCPP_Android 中的 Anime4KCore 中的文件，但是提示 E:/Work_Space/Anime4KCPP_Android/app/src/main/cpp/Anime4KCore/include\AC.hpp:17:10: fatal error: 'ac_export.h' file not found
ac_export.h 这个头文件又是哪里的呢？

主库最新代码的ac_export.h是core里面的CMakeLists.txt生成的。
另外Anime4KCPP_Android自带的Anime4KCore不可以直接编译吗？我看你将里面的Anime4KCore替换为了2.5.0 Release的。

clone Anime4KCPP_Android ，然后修改 CMakeLists.txt 中到 OpenCV OpenCL EIGEN3 路径之后，rebuild 出错，提示：

上面那个提示是 OpenCV 3.X 的，将 OpenCV SDK 换成 4.8.1 之后，错误提示如下：

因为很久没搞了，一些细节我可能遗忘了，所以我自己试了一下，直接clone Anime4KCPP_Android然后编译，一切正常，未发生上述报错。
我的环境：
- Win11，Android Studio最新版现装的
- OpenCV：4.8.1版本android sdk
- OpenCL：so库是手机里扒下来的，头文件来自KhronosGroup（具体后面说）
- Eigen 3.4.0
编译过程：clone后直接Android Studio打开项目，此时自动下载gradle7.0.2和ndk 21，因为最新AS自带java版本太新的问题会报错提示让升级gradle，自动升级就行，去设置好CMake里依赖的路径之后可以直接编译，不需要额外操作。
上面提到的OpenCL头文件问题，我用的的头文件是编译OpenCL SDK项目后生成的，理论上就是OpenCL-Headers和OpenCL-CLHPP里的头文件，应该可以直接从这两个项目下载放在一起就行，不需要先编译一遍SDK。
对比，我觉得您的问题可能在于opencl，在此提供一份我使用的opencl库供测试：
opencl.zip
顺便测试了一下把ndk升级到比较新的25版本也可以正常编译。

不知道该用什么语言来形容了，白天整整折腾了一天，就差重装电脑了，按照您到步骤一步一步操作，却始终还是出错
晚上回家继续折腾，莫名其妙到好了，回想之前到操作，应该是又升级了一次 gradle
现在的 gradle 及插件版本分别是 7.5/7.4.2
最后祝您备考成功，好运连连！
