nit: These messages potentially can be useful for other CMake generators. Could you move them to some common space, maybe in the main CMakeLists.txt?

Set /DEPENDENTLOADFLAG to 2000 (LOAD_LIBRARY_SAFE_CURRENT_DIRS) in Windows umf.dll builds (MSVC only).
With this flag, loading a DLL for execution from the current directory is only allowed if it is under a directory in the Safe load list.
In addition, there is a new test written in Power Shell that uses dumpbin.exe to check that this flag is set correctly.
Detailed information about the flag can be found at: https://learn.microsoft.com/en-us/cpp/build/reference/dependentloadflag?view=msvc-170
and: https://learn.microsoft.com/en-us/windows/win32/api/libloaderapi/nf-libloaderapi-loadlibraryexa
