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.ht ml Best Regards Roman Von: CMake [mailto:[email protected]] Im Auftrag von Michael Jackson Gesendet: Sonntag, 05. Juli 2015 18:07 An: [email protected] Betreff: Re: [CMake] Setting CXX_STANDARD 11 Enables GNU Extensions Is there a project wide CXX_STANDARD_REQUIRED that I can set? 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.

From: CMake [mailto:[email protected]] On Behalf Of digitalriptide Sent: Friday, July 3, 2015 1:56 PM To: [email protected] <mailto:[email protected]> Subject: [CMake] Setting CXX_STANDARD 11 Enables GNU Extensions 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?
