Using Allegro 5 library with Jetbrains CLion

Question

I am using CLion on Windows with MinGW (gcc/g++). I spend few hours working out why I cannot compile simple program, because I have issues with linking everything.

I tried to combine all found solutions on the Internet, applied changes which helped other people.. Still I am leaving with problems.

Here is my main.cpp:

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

using namespace std;

int main(int argc, char **argv) {
    cout << "Hello, World!" << endl;

    al_init();
    return 0;
}

And CmakeList.txt:

cmake_minimum_required(VERSION 3.6)
project(untitled)

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

set(SOURCE_FILES main.cpp)

LINK_DIRECTORIES(allegro/lib)
INCLUDE_DIRECTORIES(allegro/include)
add_executable(untitled ${SOURCE_FILES})

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


file(GLOB LIBRARIES "allegro/lib/*.dll.a")
message("LIBRARIES = ${LIBRARIES}")

TARGET_LINK_LIBRARIES(untitled  ${LIBRARIES})

That is what build process pops out:

"C:\Program Files (x86)\JetBrains\CLion 2016.3.3\bin\cmake\bin\cmake.exe" --build C:\Users\Adrian\CLionProjects\untitled\cmake-build-debug --target untitled -- -j 8

I have downloaded Allegro 5 x64 version, tried both allegro-mingw-gcc5.3.0-x64-dynamic and static from here: https://github.com/liballeg/allegro5/releases

Thank you

You must use the same version of compiler as was used to build the allegro binaries. Otherwise it just won't work right.
