As explained this package can be used as a dependency, in order to do this the following should be added to the package.xml file of your own package:

<build_depend>custom_msgs</build_depend>
<exec_depend>custom_msgs</exec_depend>

If adding this gives error you could also try to use this instead:

<depend>custom_msgs</depend>

find_package(catkin REQUIRED COMPONENTS
  custom_msgs
)

generate_messages(
