'if constexpr' isnt supported below gcc7(even with -std=gnu++17), so here's a quick fix to handle it. In debian stretch, gcc7 isn't stable. I am not sure if clang would need a similar thing, but I figured id make the pull request to bring it to your attention.
I am not sure if cmake would handle this(it probably doesn't) because I use a separate makefile to build
