CMake support for flang MSVC was broken and has been merged recently [1].
CMake 3.28 will have all the latest fixes required for Flang + MSVC combination.

Compiling Fortran OpenBLAS project with llvm-17 and latest CMake still caused issues which were fixed by #66516 which depends on #66270

This issue aims to backport both these PRs to 17.x to have Flang successfully build projects like OpenBLAS which used along MSVC.
