Add a directory to DLL search path for Windows.

Say you are building a library, library_name, which loads some 3rd party shared libraries from code:priv_dir(library_name)/lib. It's quite easy to add rpath on *nix systems, but we don't really have rpath in Windows.

Therefore, we have to use AddDllDirectory to manually add the directory that contains these .dll files to the search path.

usage

 Usage 

:ok = 
  case os:type() of
    {win32, nt} -> dll_loader_helper_beam:add_dll_directory("/SOME/DIRECTORY")
    _ -> ok
  end

Note that calling dll_loader_helper_beam:add_dll_directory/1 on *nix systems will NOT have any effect, and ok will be returned.
