Hi, we always build gazebo-rcll with a system installation of spdlog which works fine. I am not sure what version is downloaded via FetchAndDeclare, but I will try it out on my PC later and check if there is some sort of bug there, since I never use it.

The problem is that freeopcua ships with its own copy of spdlog, which then clashes with the target imported via FetchContent.

As @pkohout said, if you install spdlog on your system, both freeopcua and gazebo-rcll will include the system version, which should fix the issue.
