Building error #2
Description
Hi, I would like to use the work in the repository but when I compile I get
/usr/bin/ld: CMakeFiles/gcn_ftr.dir/src/main.cc.o: in function main': /home/michele/semantic_feature_points/src/main.cc:22: undefined reference to cv::imread(std::string const&, int)'
/usr/bin/ld: /home/michele/semantic_feature_points/src/main.cc:70: undefined reference to cv::imshow(std::string const&, cv::_InputArray const&)' /usr/bin/ld: CMakeFiles/gcn_ftr.dir/src/GCNextractor.cc.o: in function Mat':
