Hi @mudassirali4113 , thanks for raising the issue.

Makefile is supported by SAM CLI as a build method. Could you share your template to see why it didn't work?

You can also refer to https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/building-custom-runtimes.html for examples of the templates.
