libmapbox-variant-dev binary package in Ubuntu Bionic ppc64el

 Mapbox variant has the same speedy performance of boost::variant but is
 faster to compile, results in smaller binaries, and has no dependencies.
 .
 Mapbox variant has been a very valuable, lightweight alternative for
 apps that can use c++11 or c++14 but that do not want a Boost dependency.
 Mapbox variant has also been useful in apps that do depend on Boost,
 like Mapnik, to help (slightly) with compile times and to majorly lessen
 dependence on Boost in core headers.
