I had to nuke the flags targetting spdlog_header_only because in CMake, an interface target apparently really only supports the INTERFACE option. As I am only targeting Linux, the MSVC changes rely on spdlog's CI and manual code review. That said, it makes sense to also stop forcing these options on third party code, assuming that the CMake installations work the same on Windows. Fixes #1104
