There is no general way of doing it because every program's configure
script is different.

Autoconf is a braindamaged pile of crap designed by imbeciles, but naive
developers keep trusting that it will take care of their build problems
somehow.

However, I'm surprised you're having that much trouble. This stuff
generally works if you're building packages using a machine's native
toolchain, to be installed in standard locations on that machine.

Environment variables can indeed influence configure scripts, and this can be a
huge time saver. For instance, most of the cross-compiling idiocies in the bash
configure script can be circumvented by hard-coding the answers to some of
those tests and exporting them as environment variables. In Autoconf-generated
scripts, you usually have to use internal variables for this which are named
something like ac_config_whatever, or something similar.

There is not 100% consistent convention. You have to read the configure
script to see where the decision is being made which is going wrong,
and which environment variable it hinges on, if any, etc.

Hahaha.
