Using an external fmt lib should cause the spdlog::spdlog target to have a dependency on fmt lib - so that a consuming project does not need to call find_package(fmt) and target_link_libraries(... fmt::fmt). To this end a new cmake option SPDLOG_FMT_EXTERNAL is introduced which makes spdlog depend on fmt lib and defines the SPDLOG_FMT_EXTERNAL macro to avoid using the bundled fmt lib. The value of SPDLOG_FMT_EXTERNAL is also stored in the installed spdlogConfig.cmake and if it is ON find_dependency() is used to ensure the fmt::fmt target is imported.
