Cryptic error when test node name start with run_tests_

[masters3d]

CMake Error at /opt/ros/kinetic/share/catkin/cmake/test/tests.cmake:114 (add_dependencies):
  Cannot add target-level dependencies to non-existent target
  "_run_tests_mynode".

  The add_dependencies works for top-level logical targets created by the
  add_executable, add_library, or add_custom_target commands.  If you want to
  add file-level dependencies see the DEPENDS option of the add_custom_target
  and add_custom_command commands.

HI @masters3d, may I ask for the top level CMakeLists.txt where this error message occurred?

The posted CMake code doesn't seem to match the described problem. It doesn't contain anything named mynode.

It looks like the issue isn't that the target started with run_tests_, but that the target was named run_tests_${PROJECT_NAME}. #964 adds a friendlier error message for this case.
