From 1338a4b72659ce08eacb9de0205fe16202a22d9c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 28 May 2019 10:23:08 +0200 Subject: [PATCH] Makefile: Reuse all's recursion machinery for clean and install MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Targets "clean" and "install" run make recursively in a for loop. This ignores -j and -k. Target "all" depends on SUBDIR/all to recurse into each SUBDIR. Behaves nicely with -j and -k. Put that to use for "clean" and "install": depend on SUBDIR/clean or SUBDIR/install, respectively, and delete the loop.
