Many, many errors when running SOIL

[androbytes]

When I run my code, I get the error:
LNK2005 _stbi_zlib_decode_noheader_malloc already defined in stb_image-1.09.obj
I also get other errors like buffer already defined and I am very confused. I have defined _CRT_SECURE_NO_WARNINGS;
I have a folder with the include and the src.

Thanks!

I also have included SOIL in my file.
