| Fortran_PREPROCESS |
| ------------------ |
| |
| .. versionadded:: 3.18 |
| |
| Control whether the Fortran source file should be unconditionally |
| preprocessed. |
| |
| If unset or empty, rely on the compiler to determine whether the file |
| should be preprocessed. If explicitly set to ``OFF`` then the file does not |
| need to be preprocessed. If explicitly set to ``ON``, then the file does |
| need to be preprocessed as part of the compilation step. |
| |
| When using the :generator:`Ninja` generator, all source files are |
| first preprocessed in order to generate module dependency |
| information. Setting this property to ``OFF`` will make ``Ninja`` |
| skip this step. |
| |
| Use the source-specific :prop_sf:`Fortran_PREPROCESS` property if a single |
| file needs to be preprocessed. If the variable |
| :variable:`CMAKE_Fortran_PREPROCESS` is set when a target is created its |
| value is used to initialize this property. |
| |
| .. note:: For some compilers, ``NAG``, ``PGI`` and ``Solaris Studio``, |
| setting this to ``OFF`` will have no effect. |
