Ninja generator dependency cycle with Fortran [OBJECT_OUTPUTS/OBJECT_DEPENDS]

I am attempting to bootstrap flang using the Ninja generator. It works except for one issue that I haven't been able to find a solution for. When compiling a particular object file, flang produces a byproduct which is needed for compiling other object files. For the makefile generator, this is expressed as such:

# State the module that the source is producing
set_source_files_properties(
  iso_c_bind.F95
  PROPERTIES
  OBJECT_OUTPUTS ${CMAKE_Fortran_MODULE_DIRECTORY}/iso_c_binding.mod
  )

# State a dependency on the module
set_source_files_properties(
  ieee_arithmetic.F95
  ieee_exceptions.F95
  PROPERTIES
  OBJECT_DEPENDS ${CMAKE_Fortran_MODULE_DIRECTORY}/iso_c_binding.mod
  )

The problem is that this is a direct cause of the following error:

ninja: error: dependency cycle: runtime/flang/CMakeFiles/flang_static.dir/Fortran.dd -> runtime/flang/CMakeFiles/flang_static.dir/ieee_arithmetic.F95-pp.f95.ddi -> runtime/flang/iso_c_binding.mod -> runtime/flang/CMakeFiles/flang_static.dir/iso_c_bind.F95.obj -> runtime/flang/CMakeFiles/flang_static.dir/Fortran.dd

The only way that I have found around this that doesn't cause race conditions is to link a library that contains that one file and make it a dependency of other libraries including those sources. It probably extends the build time by a few seconds, so it is not the end of the world, but I think this is probably a bug in the ninja generator.
