[CMake] Setting CXX_STANDARD 11 Enables GNU Extensions

[digitalriptide]

If I enable C++11 for some target via
set_target_properties( SomeTarget PROPERTIES CXX_STANDARD 11 )
set_target_properties( SomeTarget PROPERTIES CXX_STANDARD_REQUIRED ON )
with GCC, the code will then compile with -std=gnu++11. Compiling with
-std=gnu++11 enables C++11 *and* the GNU extensions. Is there an option
that will result in -std=c++11 in lieu of -std=gnu++11, to build without
the the GNU extensions?

Thank you!
