Actually, in the real case I am building a library.  It contains 
several hundred Fortran files with just a few C++ files that act as a 
wrapper to the library.  It is much more convenient to create the 
single library than it would be to create two sets of libraries.   I 
have the whole thing working right now, I was just looking for 
optimizations to the CMakeLists.txt and was looking for a better 
understanding of mixed language projects.  I would recommend specifying 
the limitations of mixed language projects but not necessarily 
discouraging the functionality.  It is _very_ useful to be able to do 
this kind of thing in CMake.
