Hi, you must set the following in the root CMakeLists.txt file: set(CMAKE_CXX_STANDARD 11) set(CMAKE_CXX_STANDARD_REQUIRED ON) Did you mean that? http://www.cmake.org/cmake/help/v3.2/variable/CMAKE_CXX_STANDARD.html http://www.cmake.org/cmake/help/v3.2/variable/CMAKE_CXX_STANDARD_REQUIRED.html Best Regards Roman *Von:*CMake [mailto:cmake-boun...@cmake.org] *Im Auftrag von *Michael Jackson *Gesendet:* Sonntag, 05.

I am wanting to migrate our project to C++ 11 and would rather set something in the project root rather than find every place where our own and our customers plugin codes create a target.

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?
