If I'm not mistaken, the nlohmann_json dependency is only used by mangoapp ([src/meson.build](https://github.com/flightlessmango/MangoHud/blob/efdcc6d2f54e37a3a32475453407f1eb33d1bef2/src/meson.build#L248)), and AFAICT, is not built, nor installed by default ([meson_options.txt](https://github.com/flightlessmango/MangoHud/blob/efdcc6d2f54e37a3a32475453407f1eb33d1bef2/meson_options.txt#L17)).

I could be wrong, as this is my first time working with meson. If not, maybe a mangoapp subpackage should be added instead? Ala its [AUR](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=mangohud) counterpart?

Anyway, I'm marking this with WIP for now.
