This is a autoconf, automake and make question, rebuffed in gnulib.
It's partly autoconf because autoconf stages dummy dependency files
so the make include function won't choke. It is partly make because
I find it a bit tricky getting the dependencies just right. It is,
I think, mostly an automa
Make fails to restrict output to just directories when a wildcard
contains both a trailing slash and internal slashes, even though it does
the right thing with no internal slashes.
$ mkdir /tmp/example
$ cd /tmp/example/
$ touch a
$ mkdir b
$ printf 'all:\n\t@echo $(wildcard */)' | make -f -
b/
$
