Discussing about "Building a development environment for Windows"

No problem.
You know, the command will look for the target file looking into the folders listed in the environment variable $PATH.

Currently, I put the file into the folder that is already listed into the $PATH= ... :/usr/local/bin:/mingw/bin:/bin
So...
$ which SDL.dll
/usr/local/bin/SDL.dll

and for this new folder I'm using
$ SDL_DIR=/usr/local rebar compile
