query or Path query? I tried to export the FC variable but that did not
work either. I guess I'll have to fire up yet-another virtual machine.
was just hoping to bounce back and forth between the compilers on the
same machine.

It uses the check_language macro:

   # if we are not using MSVC without fortran support
   # then just use the usual add_subdirectory to build
   # the fortran library
   check_language(Fortran)
   if(NOT (MSVC AND (NOT CMAKE_Fortran_COMPILER)))
     add_subdirectory(${subdir})
     return()
   endif()

So, if your visual studio supports fortran, it will use it.
