ok, here is main CMakeList.txt:
cmake_minimum_required(VERSION 2.6)
PROJECT(AgathaHud)

#if you don't want the full compiler output, remove the following line
SET(CMAKE_VERBOSE_MAKEFILE ON)
SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/bin)
SET(LIBRARY_OUTPUT_PATH ${PROJECT_BINARY_DIR}/bin/libs)
SET(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake/modules)
find_package(Poco REQUIRED)
find_package(ARToolKit REQUIRED)
find_package(OpenCV REQUIRED)

SUBDIRS(src)

here is the second CMakeList.txt file which is in the src folder:
#this is just a basic CMakeLists.txt, for more information see the cmake manpage

#add definitions, compiler switches, etc.
ADD_DEFINITIONS(-Wall -O2)
