hi Aidin,

I'm not an Eclipse user, but here's a simple example of what would go
into CMakeLists.txt to link against an external library:
http://www.ros.org/wiki/rosbuild/CMakeLists/Examples#Linking_against_an_external_library
. If the library is not in the default linker search path, you should
also call `link_directories(/path/to/dir/with/libcurl)`.
