( Edit: It can also be the VS /std:c++latest switch - whichever is possible. I prefer it to be 'nice' and not manually looping through CXX_COMPILE_FLAGS and removing the string '/std:c++14' or some hack like that. So my question is, what's the best (or least ugly) way to do this with CMake? And in a way so it'll also work for gcc and clang? I'm happy to use a very recent CMake version (3.8 or 3.9). I've tried set(CMAKE_CXX_STANDARD 17) but it has no effect, in fact the CMake documentation mentions that CMAKE_CXX_STANDARD has no effect on VS anyway.Īs for adding a C++17 feature to target_compile_features, it doesn't seem like there are any yet (even in CMake-3.9.0-rc5), and even if there were, I'm specifically only using std::optional from C++17, and there's no target_compile_features flags for library features like std::optional. No waiting for our editor to update auto completion. If I just add it manually, I get the not-so-nice warning because both flags are present:ġ>cl : Command line warning D9025: overriding '/std:c++14' with '/std:c++17' On linux, we get to run cmake & make and were recompiling very quickly. However I'm having trouble switching this to C++17 (i.e. This adds /std:c++14 in VS2017 (which might be the default anyway?). Target_compile_features(mylib INTERFACE $) Using Cmake, we use the following command cmake CMakeLists.txt -G 'Visual Studio 11' to generate a Visual Studio 2012 solution file, which by-default uses /fp:precise as floating point option. Set(MY_CXX_COMPILE_FEATURES cxx_generic_lambdas cxx_range_for cxx_strong_enums) Set(CMAKE_CXX_EXTENSIONS OFF) # -std=c++11 instead of -std=gnu++11 I'm using the 'modern' cross-platform way so far: set(CMAKE_CXX_STANDARD 14) I tried several combinations how to add the min version ,'5. This way the subsystem flag is not recognized and set to CONSOLE. I'm trying to add the /std:c++17 compiler flag to VS2017 with CMake. Cmake seems to remove the (escaped) double quotes and places the linker flag to 'Addition Options' in the Visual Studio project: /SUBSYSTEM:WINDOWS,5.01.
