Unfortunately there is no way I can see to control the output directory. It is 
always the current working directory.

One can put two commands, e.g. something like:

```
set(CMAKE_Fortran_PREPROCESS_SOURCE
   "<CMAKE_Fortran_COMPILER> ... -d -qnoobject <SOURCE>"
   "mv <WHEREVER_XL_PUTS_IT> <PREPROCESSED_SOURCE>"
    )
```

Filling in `<WHEREVER_XL_PUTS_IT>` may be difficult.  I've observed:

* `/path/to/foo.F`    ==>  `./Ffoo.f`
* `/path/to/foo.F90`  ==>  `./Ffoo.f90`

CMake would need to be taught to produce a `<PLACEHOLDER>`
for this value, and it would need to know the mapping that
xlf uses for extensions.

Does xlf have a way to control in what directory the file is placed?
