Hi again,
I accidentally sent the previous mail
Continuing to the previous mail...
Also in the requirements, you told me to provide an option in MakeFile
`make dist` to build the
external library. But dlg uses meson build system and I don't have any idea
how to combine
meson build system with MakeFile, therefore could you provide me some
references from where
I can read about doing this...

Thanks,
Priyesh
