Hi Mostafa, first things first: If you're trying to use things from the GNU Radio main tree, refer to [1].
If you want to use external libraries, you will need to modify the CMakeLists.txt in your module directory and in your lib/ directory. In the main CMakeLists.txt you will find a paragraph starting with "# Find *** build dependencies"; after that you'll see lines like "find_package(some_library)"; some_library matches a script Findsome_library.cmake in the cmake/Modules subdirectory. You might need to write your own, but most probably someone else has already done that for you, and you can use his code. This script will set some variables pointing to the header files and to the linkable library; you will have to add these to the include_directories(..) variable and link_directories(..), respectively. In the lib/CMakeLists.txt, you will need to extend the variables of the same names, and set the target_link_libraries accordingly (for both the main library and the test). To see a modern implementation of this with some interesting external dependencies, maybe take a look at http://git.osmocom.org/gr-fosphor/tree/ (CMakeLists.txt, lib/CMakeLists.txt, cmake/Modules/) .
