# Story time:
#   I tend to use cmake for projects these days, but I'm not excatly happy with it's support
#   for cross-compiling. Sure, it's flexible enough that you do almost anything, but anything
#   advanced (like compiling host tools or building multiple platforms simultaneously)
#   requires janky usage of external projects.
#   So I set aside some time to explore other build systems to find one that better supported
#   my needs.
#   I spent some time exploring meson, it had first-party understanding of compiling host tools
