# Add a custom command to generate a new shader_cache_version hash when any of the following files change
# NOTE: This is an approximation of what files affect shader generation, its possible something else
# could affect the result, but much more unlikely than the following files. Keeping a list of files
# like this allows for much better caching since it doesn't force the user to recompile binary shaders every update
