+# /B: liba.so libb.so
+# /usr/lib: liba.so libb.so libc.so libd.so
+#
+# and /usr/lib is a system directory.
+#
+# Note: If RESOLVE_LIBRARIES() resolves a link line differently from
+# the native linker, there is a bug in this macro (please report it).
+#
+# RESOLVE_INCLUDES (XXX_INCLUDES INCLUDE_LINE)
+# This macro is intended to be used by FindXXX.cmake modules.
+# It parses a compile line and resolves all includes
