Fortran_FORMAT -------------- Set to ``FIXED`` or ``FREE`` to indicate the Fortran source layout. This property tells CMake whether a given Fortran source file uses fixed-format or free-format. CMake will pass the corresponding format flag to the compiler. Consider using the target-wide :prop_tgt:`Fortran_FORMAT` property if all source files in a target share the same format. .. note:: For some compilers, ``NAG``, ``PGI`` and ``Solaris Studio``, setting this to ``OFF`` will have no effect.
