Fortran_FORMAT
--------------

Set to FIXED or FREE to indicate the Fortran source layout.

This property tells CMake whether the Fortran source files in a target
use fixed-format or free-format.  CMake will pass the corresponding
format flag to the compiler.  Use the source-specific Fortran_FORMAT
property to change the format of a specific source file.  If the
variable CMAKE_Fortran_FORMAT is set when a target is created its
value is used to initialize this property.
