LP Simply not working

[lukaschod]

I see this repo was done 10 years ago so not sure I will get the answer.
However I can not seem to get LP working even with very simple examples like:

int main(int argc, char *argv[]) {
	Matrix_2D* m = Matrix_2D_new(4, 2);
	Matrix_2D_set_all(m,
		-50.0, -50.0,
		50.0, -50.0,
		50.0, 50.0,
		-50.0, 50.0);
	Polygon* polygon = Polygon_new_given_matrix(m, 1);
	Point* point_pia = Geometry_find_biggest_inscribed_circle_in_polygon(polygon, METHOD_LP);
	return 0;

point_pia end up being NULL.
