Suppose I have a simple makefile like:
hello:
echo "hello world"
bye:
echo "bye bye"
Then in bash I want something like:
make h < tab >
so it can complete to
make hello
I found a simple way like creating empty files hello
and bye
but I'm looking for something more sophisticated.
This answer from 2010 is outdated - the project mentioned here seems to have been discontinued.
Could this be what you're looking for?

make [Tab] would complete on all targets in Makefile. This project was conceived to produce programmable completion routines for the most common Linux/UNIX commands, reducing the amount of typing sysadmins and programmers need to do on a daily basis.
