# Latest upstream package provides both CMake and autotools building.
# Unfortunately Linux distros and homebrew build the package with autotools,
# so they do not ship the CMake Config file, but only the pkg-config files.
# vcpkg and Conan do ship Config files.
# So try config files first, and then use the regular find_library / find_path dance with pkg-config
# paths as hints.
# We can't create the same interface imported target multiple times, CMake will complain if we do
# that. This can happen if the find_package call is done in multiple different subdirectories.
