> @CarlosAlbertoEnciso My apologies for this fail, thank you for reverting this change! Before committing I ran tests on msvc and, as it turned out, it allows to not specify ObjectYAML in CMakeLists.txt, but that doesn't work everywhere and linker fail. I reproduced the fail by using WSL and I made sure that adding ObjectYAML to theCMakeLists fix build. Do I need to recreate this PR with the addition of the dependency in CMake?

@Seraphimt No problem. A merged PR can't be reopened. You are correct.
You would need to recreate this one with the CMake changes.
