How do you define the options you see in ./configure --help?

问题

I'm currently trying to set up a package to be installed with autotools.

In most, if not all, major software packages, configure --help lists a large number of options like ./configure --ENABLE-FLOAT, etc. I was wondering where I can define these options.

Thanks,

Sam

Use AC_ARG_ENABLE and AC_ARG_WITH in your configure.ac file.
