problem with gazebo 1.9.0 [closed]

edit

Hello Dear All,

I've used standalone gazebo (1.8.6) without any problems and today i update it to (1.9.0) and now when i run my code i got this error:

/home/vahid/My_WorkSpace/Project_Code_5_Qt4/CommonHeaders.hh:2: error: gazebo/transport/transport.hh: No such file or directory

also i add gazebo to cmake of my project in this way:

#//////////////////////////////////////////////////////////***Gazebo
include(FindPkgConfig)

if (PKG_CONFIG_FOUND)
  pkg_check_modules(GAZEBO gazebo)
endif()

include_directories(${GAZEBO_INCLUDE_DIRS})
link_directories(${GAZEBO_LIBRARY_DIRS})

also i call headers file of gazebo in this way:

/////////////////////////////////////////////////// Gazebo Headers
#include "gazebo/transport/transport.hh"
#include "gazebo/msgs/msgs.hh"
#include "gazebo/gazebo.hh"
#include "math/gzmath.hh"
#include "gazebo/common/Image.hh"

as i said in gazebo 1.8.6, i don't have any problem and this problem is after updating gazebo to 1.9.0. by the way when i add gazebo-1.9 to address of headers file (#include "gazebo-1.9/gazebo/transport/transport.hh"), my problem is solved but i should add gazebo-1.9 to all headers! any one know what is my fault or what should i do?
