scene_text_detection.cpp:(.text.startup.main+0xe1a): undefined reference to `std::regex_token_iterator<__gnu_cxx::__normal_iterator<char const*, std::string>, char, std::regex_traits<char> >::regex_token_iterator()'

regex can be used with GCC 4.9.0+ only: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53631
