How Can I Globally Use ISO C++ 20 for all new projects

[tmitchmachine]

Hi I'm wondering if there is a way to globally apply dialect to my project so it works for all new projects. As a mac user I have issues with red squiggly lines under my code that aren't errors and I have to update this on new files is there a way to globally update it to for example

You probably want to use other ways to manage your projects than the classic managed build system for several reasons. One is that the CDT C++ parser is not fully C++20 compliant and even with the dialect properly configured you will run into red squiggly lines if you use C++ 20 features it doesn't support. Look into using CMake projects with the LSP Editor/clangd backend.
