The core library will always be built with C++17, but we test our headers / examples under 17 and 20. commit4b24f26b66Author: Allison Piper <alliepiper16@gmail.com> Date: Sat Apr 6 16:21:42 2024 +0000 Pass CUDA FLAGS to install tests. commit4fb672ae91Author: Allison Piper <alliepiper16@gmail.com> Date: Sat Apr 6 15:43:41 2024 +0000 Add newer GCC (13) and Clang (17, 18).
