Code doesn't compile

[withinboredom]

It isn't clear what version of what dependencies are required to build this. It doesn't compile on my machine, first, I had to disable warnings in libaesrand:

withinboredom@Legion:~/code/witness-encryption-demos$ ./build.sh

builddir = /home/withinboredom/code/witness-encryption-demos/build

Perhaps it is worth including a Dockerfile to have something that is reproducible? As it is now, it is susceptible to bitrot and, in fact, has already rotted away to useless text files.

I am having similar issues with compiling. However, it appears to be dependency on FLINT library.
