I'm a beginner of ros, I met a problems about creating my first topic. The flowing is the problem,it just a warning,the real error is that the cmake can not find the *.h which I had included in my *.cpp, but I think it had a relation with this waring : "Policy CMP0046 is not set: Error on non-existent dependency in add_dependencies." Is it the problem of Cmake's version ? How can I solve it ? my Cmake version is 2.8.3 --- [Visit Topic](https://discourse.ros.org/t/some-problems-about-creating-my-first-msg/4780/1) or reply to this email to respond.
