I don't want to burden you with work, so don't feel obliged in any way. This is simply my opinion (there are also good reasons for newer C versions). In all my personal projects, I don't have any newer versions than C99 or C++11 (most are even C++98/03). I recently even migrated a compiler backend framework from C++17 to C++11 to use it: https://github.com/rochus-keller/eigen/ https://github.com/rochus-keller/eigen/. I could do the same with your code if I would use it, but first I have to move forward in other projects. Concerning cmake: I only use it if unavoidable; instead I implemented my own build system (https://github.com/rochus-keller/busy/ https://github.com/rochus-keller/busy/) some years ago which I now use for most of my personal projects.
