-- Supported systems: Windows, Linux, MacOS

-- Windows (Visual Studio) build supports x86, x86_64, and ARM64.
-- Linux build supports x86_64 and ARM64.
-- MacOS build supports x86_64 and ARM64, and it supports cross-compilation.

-- Global settings

-- Default: Build Lua, Irrlicht, miniaudio from source on all systems.
--          Don't build event, freetype, sqlite, jpeg, png, zlib, opus, vorbis on Linux or MacOS, use package manager,
--          but build them on Windows, due to the lack of package manager on Windows.
