for everyone

this uses libmgba and the latest (as of writing) development build of SDL3 with webcam support, both as submodules.

git submodule update --init

for unixesques

cmake -B_build
make -C_build -j$(nproc)
_build/cgbwebcam gbcamera.gb # provide your own rom, of course

for windows

just point visual studio at the CMakeLists.txt, apparently that's a thing it supports now.

make sure you provide the gbcamera rom as argv[1].
