Adding a minimum required C++ standard of C++17 to the generated C++ object library.
This ensures that
-std=c++17or-std=gnu++17is added to the build flags when compiling and linking the generated code.I don't think we need a CI test for this. I manually ran
just cpp_version=14, which correctly setsCMAKE_CXX_STANDARDto C++14, but CMake will tell the compiler to use C++17 anyway.Closes #261.
