All target directories, Fortran or not,  contain a cmake_clean.cmake, i.e.
  CMakeFiles/foolib.dir/cmake_clean.cmake
which in turn contains
{{{
#...
# Per-language clean rules from dependency scanning.
FOREACH(lang Fortran)
  INCLUDE(CMakeFiles/libfoo.dir/cmake_clean_${lang}.cmake OPTIONAL)
ENDFOREACH(lang)
}}}

The CMakeFiles/foolib.dir/cmake_clean_Fortran.cmake looks like this
{{{
# Remove fortran modules provided by this target.
FILE(REMOVE
  "mathconstants.mod"
  "MATHCONSTANTS.mod"
  "CMakeFiles/wzl_fortran.dir/mathconstants.mod.stamp"

  # ... for  all mod files
)
}}}

I bet this is what you're searching for :o)
