CMakeLists.txt

Line 18: set(OpenCV_DIR ../../../OpenCV-android-sdk/sdk/native/jni)       

change it to your local OpenCV-android-sdk path

[sundyCoder]

OpenCV的路径要配置成自己的。

[BrightXiaoHan]

该了路径也会报二楼的错

[wshngyf]

配置自己的OpenCV路径时，在windows平台下，复制的路径如下
E:\opencv-3.3.0-android-sdk\OpenCV-android-sdk\sdk\native\jni
windows平台路径需要修改“\”为“/”， 应该采用linux下路径格式

[yangkezun]

@wshngyf 改了还是报错啊 我都要郁闷而亡了

解决了吗
