Vitis HLS链接opencv库失败，导致对应的头文件无法识别

在project setting中已经包含了对应的库的路径但是还是显示没有链接到对应的源文件？用的是Vitis HLS2020.2，按照最新的Vitis HLS开发教程来的。显示错误的问题处已经解决了，但是又显示了新的问题，教程上显示需要更改sobel算子的文件，需要对xFSobelFilter3x3函数进行更改，已经按照教程进行了对应更改，但是由于 xFSobelFilter3x3函数中调用了ProcessSobel3x3函数，该函数中也使用到了XFCVDEPTH_IN这个参数，按照这样说的话，ProcessSobel3x3函数也是需要更改的，请问该如何更改呢？
