Adding a library to cmake
===

I am trying to compile a library called [SDL_draw][1] using cmake . 
After i download and install it the library files goes to /usr/local/lib and is named libSDL_draw.a ,so i edited the CMakeLists.txt to read this . 

    link_directories(
    	/usr/local/lib
    )
    include_directories(/usr/local/lib)

    ADD_EXECUTABLE(point_trajectory point_trajectory.cpp)

    TARGET_LINK_LIBRARIES(point_trajectory SDL_draw)

The cmake succeeds but when i "make" the project after cmake it still cannot find SDL_draw.h .  

    fatal error: SDL_draw.h: No such file or directory
    compilation terminated.
    make[2]: *** [CMakeFiles/point_trajectory.dir/point_trajectory.cpp.o] Error 1
    make[1]: *** [CMakeFiles/point_trajectory.dir/all] Error 2
    make: *** [all] Error 2
