From 925af4ef821955adf66478a4d1ea6327316b107d Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Tue, 27 Feb 2024 17:02:27 +0100 Subject: Makefile: check for cppcheck's --check-level option in cppcheck target Don't run cppcheck to find out if the --check-level=exhaustive option is available, unless we're actually going to run cppcheck later. To avoid this, move this check under the cppcheck target, and implement it in shell script instead of using Makefile directives, because we can't easily implement conditionals in recipes.
