Problems referencing Allegro5 addons - c++

Question

I'm trying use Allegro5 in CLion but I can't references addons althought it can find header and lib files.
I have the library in "/usr/lib" and headers files in "/usr/include", besides, I have the library and headers in the proyect directory.
I can use and compile this:
[..]
al_set_window_title(display, "title");
al_clear_to_color(al_map_rgb(4,0,90));
ALLEGRO_COLOR electric_blue = al_map_rgb(44, 117, 255);
But I can't compile this (in spite of detect header and the funcion):
#include <allegro5/allegro_primitives.h>
[..]
al_draw_line(100,500,300,500,electric_blue,6.0);
This is the error:
Scanning dependencies of target project
[ 9%] Building CXX object CMakeFiles/project.dir/main.cpp.o

CMakeFiles/project.dir/main.cpp.o: En la función `main':

make[1]: *** [CMakeFiles/Makefile2:68: CMakeFiles/project.dir/all] Error 2

It's the CMakeList.txt:
cmake_minimum_required(VERSION 3.7)
project(project)
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp [..])
SET(ALLEGRO_ROOT allegro/)
INCLUDE_DIRECTORIES( ${ALLEGRO_ROOT}/include)
LINK_DIRECTORIES( /${ALLEGRO_ROOT}/lib )
add_executable(project ${SOURCE_FILES})
TARGET_INCLUDE_DIRECTORIES(project PUBLIC ${ALLEGRO_ROOT})
TARGET_LINK_LIBRARIES(project allegro)
This is the project structure:
What am I doing wrong?

Answer 1

As you can see in your error, the reference to 'al_draw_line' in your main.cpp:80 is undefined. This is because Allegro has so many addons that you also have to link if you are using them to make it work.
To solve it, replace
TARGET_LINK_LIBRARIES(project allegro)
by
TARGET_LINK_LIBRARIES(project
allegro_acodec
allegro_audio
allegro_color
allegro_dialog
allegro_image
allegro_main
allegro_memfile
allegro_physfs
allegro_primitives
allegro_ttf
allegro_font
allegro)
Or just make the list with any addon you need. In this case, for example, for using 'al_draw_line' you only need 'allegro_primitives' to make it works.
