1Fortran_PREPROCESS 2------------------ 3 4.. versionadded:: 3.18 5 6Control whether the Fortran source file should be unconditionally preprocessed. 7 8If unset or empty, rely on the compiler to determine whether the file 9should be preprocessed. If explicitly set to ``OFF`` then the file 10does not need to be preprocessed. If explicitly set to ``ON``, then 11the file does need to be preprocessed as part of the compilation step. 12 13When using the :generator:`Ninja` generator, all source files are 14first preprocessed in order to generate module dependency 15information. Setting this property to ``OFF`` will make ``Ninja`` 16skip this step. 17 18Consider using the target-wide :prop_tgt:`Fortran_PREPROCESS` property 19if all source files in a target need to be preprocessed. 20
