C ++ Reduced spending space

I'm creating a C ++ project with Allegro 5 using code :: blocks, and I put allegro files straight into the project folder to make it simpler. I'm using functions only to display images and texts with ttf fonts and detect mouse and keyboard events, however, the allegro is much larger than that. So my project that should have use about 5 to 10 MB, ends up getting 80. I wanted to know how to identify which files are redundant and remove. I installed Allegro by putting the include and lib folders in the allegro folder within the project folder, and the contents of the bin folder next to the compiled program, making the necessary links in the code :: blocks so that it recognizes these files as part of the project. So the compiled program, even small, depends on the dll files and the allegro
