+# NOTE: Do not use this routine! Use enable_latest_css_support.cmake instead, even if you only need C++11, as the
+#       compiler always uses the strictest ("oldest") specified standard if mulitple flags are given. This will create
+#       problems when combining multiple projects (libraries...) requiring different C++ standards.
+#
 # Enable C++-11 support by selecting the appropriate compiler flag. The flag will be appended to all of the following
 # cmake variables:
 # - CMAKE_CXX_FLAGS
