From 263b9a97cf7e1e2467319c23832b705fc01190b5 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 11 Nov 2023 22:18:18 +0100 Subject: [PATCH] cmake: Fail if undefined symbols are used Make the linking of the shared library fail when undefined symbols are used. Linking undefined symbols in a shared library normally works and the linking of the binary using the shared library fails. We also compile some example applications and they failed already.
