add catkin path to cmake

edit

How do i properly use the catkin in cmake? I am trying to develop a ros controller android app using qt android with cmake. What i am trying to do is to add the find_package(CATKIN REQUIRED) inside the CMakeLists.txt file of the qt project but it says:

By not providing "FindCATKIN.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "CATKIN", but CMake did not find one. their was no findcatkin.cmake in the catkin package as i checked. So how do i solve this problem or make the catkin or ros packages compile inside the qt creator with cmake ?
