# $<TARGET_PROPERTY:Corrade::PluginManager,INTERFACE_INCLUDE_DIRECTORIES>,
# if MAGNUM_SCENECONVERTER_STATIC_PLUGINS is non-empty then CMake fails with
#
#   Target "Corrade::PluginManager" not found.
#
# unless the find_package() is here. Not sure why, probably some bug in CMake
# dependency handling? Changing target_include_directories() to PRIVATE doesn't
# help, removing it altogether helps.
