fatal error: dds/domain/DomainParticipant.hpp: No such file or directory

Hi,

When I'm trying compile ros2 application using the ROS-data-type string.hpp, get the following error. I do not understand how do link the headers 

Starting >>> simple_test
--- stderr: simple_test
In file included from /home/z0013488/ros2_dashing/src/simple_test/src/test.cpp:5:0:
/home/z0013488/ros-data-types/install/include/std_msgs/msg/String.hpp:24:10: fatal error: dds/domain/DomainParticipant.hpp: No such file or directory

Failed <<< simple_test [ Exited with code 2 ]

Summary: 0 packages finished [0.37s]

I have the file in :

/home/z0013488/rti_connext_dds-5.3.1/include/ndds/hpp/dds/domain/DomainParticipant.hpp

how and where should I link this include directory.. ??

thank you!
