From 091873e47ef700e935aa80079b63929af599a0b2 Mon Sep 17 00:00:00 2001 From: Mickaël Salaün Date: Wed, 19 Oct 2022 22:05:36 +0200 Subject: selftests/landlock: Build without static libraries MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The only (forced) static test binary doesn't depend on libcap. Because using -lcap on systems that don't have such static library would fail (e.g. on Arch Linux), let's be more specific and require only dynamic libcap linking.
