链接器找不到库，即使我用 -L 指定了它的位置

这是我的制作文件

这里

#Libraries
LIBS = -lmingw32 -lSDL2main -lSDL2 -LD:/Development/GLFW/lib-mingw/libglfw3.a -lglfw3 -lglew32s                 -lgdi32 -lopengl32

我已经用-L指定了libglfw3.a的位置，但链接器仍然抱怨并且找不到-lglfw3。它给出以下错误：

LINKING...out/src/main.o -lmingw32 -lSDL2main -lSDL2 -LD:/Development/GLFW/lib-mingw/libglfw3.a     -lglfw3 -lglew32s -lgdi32 -lopengl32
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot find -lglfw3
collect2.exe: error: ld returned 1 exit status

我正在使用 Mingw32，如果我libglfw3.a放在它的lib文件夹中，它会找到它(没有-LD:/Development/GLFW/lib-mingw/libglfw3.a(。

为什么链接器在我用-L指定库的位置时找不到库？
