Subject: meson: Deduplicate sources before clang-tidy
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=84dcbc3fd29e86bd7f541f2be8888c602095fd50;p=thirdparty%2Fsystemd.git

meson: Deduplicate sources before clang-tidy

Let's make sure we don't define the same clang-tidy
test multiple times by deduplicating sources beforehand.
We end up with the same sources in a few cases because
e.g. we reuse the same fuzz-main.c for each fuzz target.
