+# Test using the target_link_libraries command to set the
+# LINK_INTERFACE_LIBRARIES* properties.  We construct two libraries
+# providing the same two symbols.  In each library one of the symbols
+# will work and the other one will fail to link.  The import part of
+# this test will try to use the symbol corresponding to the
+# configuration in which it is built.  If the proper library is not
+# used via the link interface the import test will fail to link.
