roslib reference error

edit

I did:

string fname = ros::package::getPath("foo")

and got:

test.cpp:(.text+0x424): undefined reference to `ros::package::getPath(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

Looking at existing discussions, it seems that this is because of failure to link to roslib. https://github.com/ros/ros/issues/58

I upgraded all ros packages and tried again but did not work. Your help will be very appreciated.

ROS version: Hydro OS: Ubuntu 12.04 I installed through apt-get

CMakeList.txt:
