<built_type> doesn't work anymore with multiple tags

[facontidavide]

This doesn't work anymore:

  <export>
      <build_type condition="$ROS_VERSION == 2">ament_cmake</build_type>
      <build_type condition="$ROS_VERSION == 1">catkin</build_type>
  </export>

If I run echo $ROS_VERSION I can see either 1 or 2

Error message:

Is this the same error as #1170?

Duplicate of #1170

I think that this and #1170 are different, but IIUC the issue reported here was solved in ros-infrastructure/catkin_pkg#336.
