You could try:

SET_SOURCE_FILE_PROPERTIES(foo.f PROPERTIES COMPILE_FLAGS -DTEST_DEFINE)

At the end of the day it may not be a good idea to have fortran and c or c++ mixed
in the same library or executable.  Create libraries for fortran and link to them,
but do not try and mix the source code into the same library.
