# About this build script: it does many things, but in essence, it's
# very simple. It has 3 compiler invocations: building raylib (which
# is not done always, see logic by searching "Build raylib"), building
# src/*.c files, and linking together those two. Each invocation is
# wrapped in an if statement to make the -qq flag work, it's pretty
# verbose, sorry.
