We changed to remove SDL2 files from tinyusdz git repo to reduce repo size.

Please download SDL2 source package from:

https://github.com/libsdl-org/SDL/releases/download/release-2.30.6/SDL2-2.30.6.tar.gz

and unpack here.

Example script


wget https://github.com/libsdl-org/SDL/releases/download/release-2.30.6/SDL2-2.30.6.tar.gz
tar xvf SDL2-2.30.6.tar.gz
