CodeCoverage with Xcode (Clang): Undefined symbols for architecture x86_64

During the linking phase of my GitHub action, I encounter the following errors while using Xcode 14.2 (Clang) (not on Linux/Ubuntu):

[100%] Linking CXX executable [NAME]

clang: error: linker command failed with exit code 1 (use -v to see invocation)

It looks like that something is missing during the linking phase (maybe a flag ?). Any thoughts? Thanks 🥳

Same issue here😥

How can I solve this in my CI?
