# Los autores han migrado a rust con lo cual el código mediant git se ha reemplazado por el código "antiguo",
# es por ello que el script de compilacińo se ha modificado bastante, la lista de cambios es larqa

# Eliminada la dependéncia del zlibg1-dev
# Añadido parámetros del zlib para LCMS2
#
sudo apt-get install make libc6-dev
