nvc++compiler support (CMake 3.20)- Support for the oneAPI compiler toolchain (CMake 3.20) (nice to have for #789)
- Support for Visual Studio 2022 generators (CMake 3.21)

Therefore, I would postpone it version 0.11, because I think Ubuntu 20.04 will be stay the mainly used Ubuntu version at the release of 0.10.
CMake 3.21 was released on Jul 14, 2021. That feels a bit too new to require, but I am not blocking you. I work on platforms where I can get the latest tools 😃
