checkinstall --include option not working

I am successfully able to create a .deb package from source using checkinstall. However can someone help me with why I cannot add custom/additional files to the package created using the --include option with checkinstall. For instance I use checkinstall –-install=no --include="/home/user/*package-name*/include-list.txt" , I assume this should be sufficient to include additional files & dirs listed in the include-list.txt in the package(.deb) created. My include-list.txt is just a simple txt file and contains 1 line as follows : /etc/systemd/system/example.service & my intention is to include this .service file as a part of the package created. I have checked the checkinstall help and its seems like --include option is the way to go. Any help will be appreciated.
