我试图用Mac运行一个项目，但是，当我想执行make时，出现此错误：
library not found for -lglut
这是我们的Makefile：
CXXFLAGS= -g -Wall -Wextra -O2
LDFLAGS = -lm -lglut -lGLEW -lGLU -lGL -pthread
all: executable
executable: main.o glutils.o mat4.o vec2.o vec3.o triangle_index.o vertex_opengl.o tga.o mesh.o format/mesh_io_obj.o format/mesh_io_off.o
g++ $^ -o executable $(LDFLAGS)

clean:

PS：我已经安装了gcc和OpenGL扩展查看器
