Что не так с моим make-файлом для кросс-компиляции?

Я провел несколько дней, пытаясь перекрестно скомпилировать программу c на моей машине с Windows. код отлично работает на моей машине с Linux, но у меня было слишком много ошибок при попытке перекрестной компиляции на этой машине. Сейчас использую Cygwin и Mingw32.

    CC = x86_64-w64-mingw32-gcc
    CFLAGS = -Wall -O2 -lmingw32 -lGL -lGLU -lm -lSDL_image -lfftw3 -lftdi1 
    -mwindows `sdl-config --cflags --libs`

    OBJECTS = main.o fft.o draw.o table.o serial.o

    main : $(OBJECTS)
    $(CC) $(CFLAGS) $(OBJECTS) -o main

    %.o : %.c
    $(CC) $(CFLAGS) -c $<

    clean:
    @echo Cleaning up...
    rm -fr *.o main
    @echo Done.

Вот как выглядит мой make-файл после его редактирования до того, что, по моему мнению, было необходимо для его кросс-компиляции. Но я получаю много ошибок неопределенных ссылок. Я понимаю, что этот вопрос очень похож на несколько других, которые я просмотрел на SO, но я не могу найти свою ошибку.
