"multiple definition" Problem

[DTxplorer]

Hello I try to use the 
[stb_image](https://github.com/define-private-public/stb_image-Nim) lib.

I made this minimal test for my question.
    
    
    import stb_image/read as stbi
    
    var width, height, nrChannels:int
    var test = stbi.load("some_image.jpg", width, height, nrChannels, 
stbi.Default)
    

The compiler prints tons of errors like this.
    
    
    /some_path/nimcache/read.o: In function `stbi_image_free':
    read.c:(.text+0x4bd): multiple definition of `stbi_image_free'
    

One for every stbi function.

I just basically write the stbi readme example. I don't understand why this 
problem occurs.
