チュートリアルの初級編を進めているのですが、チュートリアル14番のコードをbuildするとエラーがでてしまいます。 以下です。

CMake Error at /opt/ros/hydro/share/catkin/cmake/catkin_package.cmake:186 (message):
  catkin_package() the catkin package 'message_runtime' has been
  find_package()-ed but is not listed as a build dependency in the
  package.xml
Call Stack (most recent call first):
  /opt/ros/hydro/share/catkin/cmake/catkin_package.cmake:98 (_catkin_package)
  beginner_tutorials/CMakeLists.txt:89 (catkin_package)

runtimeの依存性は、cmakelistに記述しているのですが、エラーが出てしまいます。msg,srvのチュートリアルを参考にしてもよく分かりません。よろしくお願いします。

Your error message points out what's missing:

CMake Error at /opt/ros/hydro/share/catkin/cmake/catkin_package.cmake:186 (message):
  catkin_package() the catkin package 'message_runtime' has been
  find_package()-ed but is not listed as a build dependency in the
  package.xml

So add message_runtime as a dependency in package.xml, as in this tutorial (that is a few session back from where you're at now):

Open package.xml, and make sure these two lines are in it and uncommented:

  <build_depend>message_generation</build_depend>
  <run_depend>message_runtime</run_depend>

Appending on @130s answer:

In package.xml you need the lines:

  <build_depend>message_generation</build_depend>
  <run_depend>message_runtime</run_depend>

In CMakeLists.txt you need:

find_package( catkin REQUIRED COMPONENTS message_generation <.... other packages.....> ) 
# note: no message_runtime in find_package

And please note that this Q&A forums language should be English. This assures that all people knowing how to solve your issue can understand you question and post an answer...
