# This macro takes a library base name as an argument, and will choose good
# values for basename_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and
# basename_LIBRARY_RELEASE depending on what has been found and set. If only
-# basename_LIBRARY_RELEASE is defined, basename_LIBRARY, basename_LIBRARY_DEBUG,
-# and basename_LIBRARY_RELEASE will be set to the release value. If only
-# basename_LIBRARY_DEBUG is defined, then basename_LIBRARY,
-# basename_LIBRARY_DEBUG and basename_LIBRARY_RELEASE will take the debug value.
+# basename_LIBRARY_RELEASE is defined, basename_LIBRARY will be set to the
+# release value, and basename_LIBRARY_DEBUG will be set to
+# basename_LIBRARY_DEBUG-NOTFOUND. If only basename_LIBRARY_DEBUG is defined,
+# then basename_LIBRARY will take the debug value, and basename_LIBRARY_RELEASE
+# will be set to basename_LIBRARY_RELEASE-NOTFOUND.
#
# If the generator supports configuration types, then basename_LIBRARY and
# basename_LIBRARIES will be set with debug and optimized flags specifying the
# library to be used for the given configuration. If no build type has been set
# or the generator in use does not support configuration types, then
-# basename_LIBRARY and basename_LIBRARIES will take only the release values.
+# basename_LIBRARY and basename_LIBRARIES will take only the release value, or
+# the debug value if the release one is not set.
