Build statically, missing cv::countNonZero(cv::_InputArray const&)

asked 2020-10-16 18:23:37 -0500

I am missing quite a few references:

libopencv_imgproc.a(filter.dispatch.cpp.o):filter.dispatch.cpp:function cv::preprocess2DKernel(cv::Mat const&, std::__ndk1::vector<cv::Point_<int>, std::__ndk1::allocator<cv::Point_<int> > >&, std::__ndk1::vector<unsigned char, std::__ndk1::allocator<unsigned char> >&): error: undefined reference to 'cv::countNonZero(cv::_InputArray const&)'

This is the build:

Build command failed.

I am building on ndk statically CMakeLists.txt:
