From 7e615a540ea346716ba3d94b4bcecb35c42d5107 Mon Sep 17 00:00:00 2001 From: Bianca van Schaik Date: Fri, 15 Jan 2021 10:20:21 +0100 Subject: file(GET_RUNTIME_DEPENDENCIES): Fix weak macOS libraries not detected Starting with Clang 12, `otool -l` reports `LC_LOAD_WEAK_DYLIB` instead of `LC_LOAD_DYLIB` for weakly linked libraries. Update the implementation of `file(GET_RUNTIME_DEPENDENCIES)` to recognize these.
