libcv_bridge.so：undefined reference to‘boost::re_detail_106000::perl_matcher<char const*, std::allocator<boost::sub_match<char const*> >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)’

I rebuild the cv_bridge with opencv3.4.0. When I ran the "catkin_make" to build cv_bridge only ,the cv_bridge is ok.But when I call the cv_bridge in my program，it has a problem that :
/home/zzq/catkin_workspace/devel/lib/libcv_bridge.so：undefined reference to‘boost::re_detail_106000::perl_matcher<char const*, std::allocator<boost::sub_match<char const*> >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)’

My program that find the cv_bridge in CmakeLists.txt will be seen as follows:

#set(cv_bridge_DIR /home/zzq/catkin_ws/devel/share/cv_bridge/cmake)
find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  sensor_msgs
  cv_bridge
)

The first line of the program is not work，so I add the “#”.
