It's not that simple, see

The only good choice for KDL is using __declspec(dllexport/dllimport)
using a macro mechanism, as is in use by RTT and OCL. So you'll need
to patch every class and free function definition using this macro.

Or use Erwin's suggestion of adding the KDL .cpp files in your C++ project.

For a quick-and-dirty solution, if you just want to try out KDL, you can
probably just add the
.cpp files in orocos_kdl/src and orocos_kdl/src/utilities to your project.
and both directories also to your include directories to take into
account the header files.
