Creates LOVE AppImage by compiling every single dependency from source.
You may want to grab all dependencies required by SDL, but not the SDL itself.
Note for Ubuntu ARM64: If APT can't find libsndio-dev and fcitx-libs-dev, make sure to add universe repository!
Afterwards, run make. love-main.AppImage (by default) will be generated. See the Makefile script for various tweakable variables.
If you're running WSL 1, run make QEMU=env instead to bypass FUSE requirement restrictions by extrating appimagetool somewhere else first.
AppRun.c is based on default AppImage's AppRun.c thus it's under MIT license.
The rest is public domain.
