If your project is autosetup-enabled, it already includes a copy of autosetup. Otherwise, the latest version of autosetup is available from the git repository at https://github.com/msteveb/autosetup

Install It

To add autosetup to a project, change directory to the project and install.

$ cd ~/src/myproject
$ ~/src/autosetup/autosetup --install --init=make
Installed local autosetup v0.6.7 to autosetup
Initialising make: Simple "make" build system

I see auto.def already exists.
Note: I don't see Makefile.in. You will probably need to create one.

Now edit auto.def as required, create Makefile.in if necessary, and use ./configure
