CUB 1.10.0 (NVIDIA HPC SDK 20.9, CUDA Toolkit 11.2)

Summary

CUB 1.10.0 is the major release accompanying the NVIDIA HPC SDK 20.9 release and the CUDA Toolkit 11.2 release. It drops support for C++03, GCC < 5, Clang < 6, and MSVC < 2017. It also overhauls CMake support. Finally, we now have a Code of Conduct for contributors: https://github.com/thrust/cub/blob/main/CODE_OF_CONDUCT.md

Breaking Changes

• C++03 is no longer supported.
• GCC < 5, Clang < 6, and MSVC < 2017 are no longer supported.
• C++11 is deprecated. Using this dialect will generate a compile-time warning. These warnings can be suppressed by defining CUB_IGNORE_DEPRECATED_CPP_DIALECT or CUB_IGNORE_DEPRECATED_CPP_11. Suppression is only a short term solution. We will be dropping support for C++11 in the near future.
• CMake < 3.15 is no longer supported.
• The default branch on GitHub is now called main.

• Added install targets to CMake builds.
• C++17 support.
