You'll need to create a Modules/Platform/Windows-CVF.cmake file where
"CVF" is replaced by the actual name of the compiler executable.  In
other such platform files you'll find alternative settings for rules
like CMAKE_Fortran_COMPILE_OBJECT.  Copy one of these and modify it to
setup the rules for this compiler.

If you get this working please post your results.
