[SOLVED] opencv my awesome library problem

edit

I have a problem when trying to run catkin_make, i am trying to build a package that uses opencv, i have added in CMakeLists : find_package(OpenCV) include_directories(${OpenCV_INCLUDE_DIRS}) target_link_libraries(my_awesome_library ${OpenCV_LIBRARIES}) but running catkin_make i get the folowing problem:

CMake Error at wificam/CMakeLists.txt:168 (target_link_libraries): Cannot specify link libraries for target "my_awesome_library" which is not built by this project.

any idead what can I do? thanks a lot

EDIT 1: this is it

cmake_minimum_required(VERSION 2.8.3)
project(wificam)

find_package(catkin REQUIRED COMPONENTS
  cv_bridge
  roscpp
  std_msgs
  image_transport
  camera_info_manager

)


catkin_package(

)

include_directories(
  ${catkin_INCLUDE_DIRS}
)



find_package(OpenCV)
   include_directories(${OpenCV_INCLUDE_DIRS})
   #target_link_libraries(my_awesome_library ${OpenCV_LIBRARIES})

add_executable(wificamp src/wificamp.cpp)
target_link_libraries(wificamp ${catkin_LIBRARIES})

add_executable(wificampc src/wificampc.cpp)
target_link_libraries(wificampc ${catkin_LIBRARIES})

add_executable(wificampb src/wificampb.cpp)
target_link_libraries(wificampb ${catkin_LIBRARIES})

add_executable(wificams src/wificams.cpp)
target_link_libraries(wificams ${catkin_LIBRARIES})

add_executable(testbridge src/testbridge.cpp)
target_link_libraries(testbridge ${catkin_LIBRARIES})

it is comented because if not i could not build it, how should I define that cmake target? I thought i had done it like it is explained in the opencv ros tutorial, i am still a noob sorry and thanks a lot
