How to embed a header file into a .nim file

[def_pri_pub]

So I'm working on wrapper for a library (stb_image) that is contained in a 
single header file. Right now if I want to get things to compile and work, I 
have to tell the nim compiler where that header file is located. For example, 
if my project structure is like this:
    
    
    src/
     - main.nim
     - header_lib.h
     - header_lib.nim
    

And I'm compiling from that src/ directory, I have to do this: nim c main.nim 
--cincludes:. I'd really like to drop that \--includes part, so whoever uses 
this wrapper only has to do the import statement.

Is there a way that I can do this without copy and pasting the source of the 
header into the .nim wrapper file?
