When i am creating a folder in storage/<customEngine>. I have placed the makefile from example folder and in the customEngine folder and have made required changes.

However, makefile is not generated in the storage/<customEngine> folder.

What change I have to make in configure or configure.in file? 

Right now, my custom engine code is similar to example code. I would like to build it first and then make the changes accordingly. But makefile is not generated. 

Appreciate your help.

Thanks and Regards,

Amith
