#  Specify the object files to compile in the sub-directories and the
#  modules which are required to specify the dependencies correctly for a F90 project.
#  Then we can export them so that they can be used in dependency lists.
#  Note that the order of compilation has been arranged carefully
#  such that compilation of files is only dependent on what has happened upstream in the make process
#  If a fortran source file uses a module then the dependency must be on both the .mod and the .o file
#  as the .mod file timestamp does not necessarily change when the module is recompiled if the contents of the mod file do not change
#  see for example: https://gcc.gnu.org/ml/fortran/2007-11/msg00013.html
# Note also that gfortran creates module files with lower case names whatever the case of the module name in the .F90 file...
