--- Comment #78 from Jan Beich <jbeich@FreeBSD.org> ---
For one, graphics/waifu2x-converter-cpp fails to detect OpenCV 3.x because

  check_include_file_cxx("opencv2/opencv.hpp" HAVE_OPENCV)

expands into

  $ cat a.cc
  #include <opencv2/opencv.hpp>

  int main()
  {
    return 0;
  }

  $ c++ a.cc -I/usr/local/include
  /usr/bin/ld: error: undefined symbol: cv::String::deallocate()
  >>> referenced by a.cc
  >>>               /tmp/a-d07f07.o:(cv::String::~String())

  /usr/bin/ld: error: undefined symbol: cv::String::deallocate()
  >>> referenced by a.cc
  >>>               /tmp/a-d07f07.o:(cv::String::operator=3D(cv::String con=
st&))
  c++: error: linker command failed with exit code 1 (use -v to see invocat=
ion)
