rtt-exercise building error

edit

I am using ros kinetic in ubuntu 16.04. My first error is:

Traceback (most recent call last):
  File "/opt/ros/kinetic/share/ros/core/rosbuild/bin/check_same_directories.py", line 46, in <module>
    raise Exception
Exception

    CMake Error at /opt/ros/kinetic/share/ros/core/rosbuild/private.cmake:102 (message):
  [rosbuild] rospack found package "controller-1" at "", but the current
  directory is "/home/robot/rtt-exercises-2.7.0/controller-1".  You should
  double-check your ROS_PACKAGE_PATH to ensure that packages are found in the
  correct precedence order.

See also "/home/robot/rtt-exercises-2.7.0/controller-1/build/CMakeFiles/CMakeOutput.log".

So when i enter command " export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/rtt-example/rtt_examples-rtt-2.0-examples/rtt-exercises/controller-1 " than i'm getting below error:

Failed to invoke /opt/ros/kinetic/bin/rospack deps-manifests controller-1
[rospack] Error: package 'controller-1' depends on non-existent package 'rtt' and rosdep claims that it is not a system dependency. Check the ROS_PACKAGE_PATH or try calling 'rosdep update'


CMake Error at /opt/ros/kinetic/share/ros/core/rosbuild/public.cmake:129 (message):


  Failed to invoke rospack to get compile flags for package 'controller-1'.

  Look above for errors from rospack itself.  Aborting.  Please fix the
  broken dependency!

I have already installed the rtt-ros-integration package and orocos-toolchain package from source. And when i enter command " source ~/ws/underlay_isolated/installd_isolated/setup.sh " it again repeates the first error. So how should i solve this error. I was practicing the rtt-example package tutorial to learn orocos basics. This package is also avialabe in [here:] ( https://github.com/orocos-toolchain/r... )

And i have installed orocos-toolchain and rtt-ros-intigration package branch 2.9.
