The first two line probably search for a pkg-config file and since  
that is not found, the program "ode-config" is found and used.

You can ignore this (one is a link to the other) and you can disable  
this with the cmake option -Wno-dev

Maybe ode-0.11.1 is not fully backward-compatible to ode-0.10?
You can make the full link line visible with "make VERBOSE=1".
