[CMake] Fortran 90 module output directories, dependency analysis

[Jed Brown]

Is there a way to specify where generated *.mod files will be placed?
Something analogous to CMAKE_LIBRARY_OUTPUT_DIRECTORY?

Also, I notice that if I delete a module file, the build fails (unlike
everything else where it will be properly regenerated).  This is with a
plain Makefile build, cmake-2.8.1, after a successful complete build:
