# For some targets, an if/wildcard combination ensures that a directory is only
# considered a dependency if it does not already exist. This ensures changing
# directory timestamps don't result in unnecessary recompiles. In other
# targets, wildcard expansion is used so that certain files are only added as
# dependencies if they already exist. Without using the wildcard function, the
# recipes fail when the files did not exist because there's no recipe for them
# in this Makefile. I attempted to use order-only prerequisites for *-src
# folders, but I ran into some problems with dependency chains; deleting
# "app-src" after creating the binary "app" then running "make" would only
# generate the config.h symlink; in order to rebuild th binary, "make" would
# have to be run again.
