Great Job

• ngx_http_brotli_filter_module.so
• ngx_http_brotli_filter_module.so
  created in /usr/lib/nginx/modules path.
  I got always compiling error on my way .

Still brotli on failing. No sure if I have to add that files in a dinamic way

These files should be generated as the result of the compilation. What's the compilation error you get?
