Can you post the exact command that cmake executes to link sc_fe_mini (with make VERBOSE=1)?

I have noticed similar linking problems that depended on the order when linking. In my case, it 
compiled when "-lpthread -lutil -lrt" were at the end of the command, but not before mfe.o and 
libmidas.a. Unfortunately I haven't found a way to tell cmake the "correct" order of the link 
libraries.

Maybe this can be fixed by adding midas as a subdirectory in your cmake project and just linking 
against the "mfe" target instead of libmfe.a.
