Hi! I was writing to find out what would be necessary to update the version of libconfig that ships with Ubuntu from 1.5-0.2 (released in 2015) to a more recent version, like 1.7.2. The version available from github just configures and compiles without any issue on Ubuntu 20: https://hyperrealm.github.io/libconfig/dist/libconfig-1.7.2.tar.gz Thanks! /a
