Making allegro5 project with CLion

Few days ago I downloaded clion to make a school project in C++ and Allegro5. First I used allegro installed with homebrew but it wasn't working so I compiled it by myself. Since I've never worked with CMake before it took me some time to include the libs and compile the project but I managed to do it. The problem is that when I try to run it it throws an error:

dyld: Symbol not found: __al_mangled_main
Referenced from: /usr/local/lib/liballegro_main.5.0.dylib
Expected in: flat namespace
in /usr/local/lib/liballegro_main.5.0.dylib

My CMakeLists.txt:

cmake_minimum_required(VERSION 3.3)
project(arkanoid)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES classes/main.cpp classes/ball.cpp classes/ball.h classes/block.cpp classes/block.h)

add_executable(arkanoid ${SOURCE_FILES})

INCLUDE_DIRECTORIES( allegro/5.0.11/include )

LINK_DIRECTORIES( allegro/5.0.11/lib )


TARGET_LINK_LIBRARIES(arkanoid  allegro_acodec
                            allegro_audio
                            allegro_color
                            allegro_dialog
                            allegro_image
                            allegro_main
                            allegro_memfile
                            allegro_physfs
                            allegro_primitives
                            allegro_ttf
                            allegro_font
                            allegro)

And for now my main.cpp looks like this:

#include <iostream>
#include <allegro5/allegro.h>

using namespace std;

int main() {

    al_init();

    return 0;

}

I'm trying to build this project on OSX. I've searched for 2 days for the solution to my problem but with no results. Not many people are using CLion and even less use it with allegro5. Could anyone have a clue what this error even mean?

Ok this one blew my mind. I don't know why I found solution only after asking on stackoverflow but I'm posting it for someone who might encounter simillar problem to mine. Change your main declaration from 

int main()

to

int main(int argc, char **argv)

and that's it. Really.
