# TODO: $<CONFIG> matches both the conumer's configuration AND the selected
# configuration of the imported target. This is ungood, and eventually we need
# a way to match only the selected configuration of the imported target. For
# historic reasons, that will probably not be $<CONFIG>, which means $<CONFIG>
# should eventually stop matching the selected configuration of the imported
# target. When that happens, this test should be changed to use the new
# mechanism, and the test cases adjusted accordingly.
# Under CMP0200 OLD, CMake fails to select a valid configuration for an
# imported INTERFACE library with no location, and will (as an implementation
# artifact) select the last configuration in IMPORTED_CONFIGURATIONS.
#
# Under NEW, CMake should select a configuration which matches the current
# build type, if available in IMPORTED_CONFIGURATIONS.
