1. A search in the CMake repository revel that `flang-new` only appear in testcases and ci-related code - not in any code that eventually end up in CMake. This indicate that the name `flang-new` is not a magic token for CMake to recognize LLVM Flang.
2. I think that [this is the merge](https://gitlab.kitware.com/cmake/cmake/-/merge_requests/7246) that first introduced LLVM Flang to CMake. It seems like the check is through preprocessor macros defined by the different compilers. See [`Modules/CMakeFortranCompilerId.F.in`](https://gitlab.kitware.com/cmake/cmake/-/blob/master/Modules/CMakeFortranCompilerId.F.in) in the CMake sources.
