Clownacy ac465d29b4 Mean CMake dependency overhaul
I'm taking a page from Dolphin's book, and including copies of each
dependency's source code. This combines the ease of use of including
pre-built libraries instead of needing to navigate a package manager
 - as is (or was) the case for MSVC - with the portability of using
packages. Granted, this method's more of a jack of all trades,
master of none, since it's *less* user-friendly than prebuilt
packages (compilation times), and you don't get the per-distro
compatibility fixes you'd get from a package manager.

You can still use system libs if you want. In fact, it's still the
default behaviour: compiling the libs manually is just a fallback.
I'll add an option to force-enable this soon, however, since it's a
nicer way to produce static MSYS2 builds than the hackish nightmare
that I was using before. Not to mention, having my own copy of the
sources means I can provide my own fixes and tweaks your package
manager may not. For example, I can combine MSYS2's FreeType
subpixel rendering with vcpkg's fix for SDL2 exporting its symbols
in static builds.
