external projects don't yet have an automated way to populate them.

When I run cmake . in the VulkanInfiniteProceduralTerrain directory on my Kubuntu 22.04 system I get an error:

CMake Error at CMakeLists.txt:118 (add_subdirectory): add_subdirectory given source "external" which is not an existing directory.

I looked for them to be pulled in as submodules so tried a:

git submodule init git submodule update

But this didn't pull anything in. I can't see any entry for modules in the .git setup so I presume this simply hasn't been setup/checked in yet.
