Lenny Maiorani ded0b5a93c CMake: Set C++20 mode in canonical cmake
Problem:
- Setting `CMAKE_CXX_FLAGS` directly to effect the version of the C++
  standard being used is no longer the recommended best practice.

Solution:
- Set C++20 mode in the compiler by setting `CMAKE_CXX_STANDARD`.
- Force the build system generator not to fallback to the latest
  standard supported by the compiler by enabling
  `CMAKE_CXX_STANDARD_REQUIRED`. This shouldn't ever be a problem
  though since the toolchain is tightly controlled.
- Disable GNU compiler extensions by disabling `CMAKE_CXX_EXTENSIONS`
  to preserve the previous flags.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Build status Fuzzing Status

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
