Perhaps you can try adding:

INCLUDE_DIRECTORIES (<path to where time_utils.h is>)

It looks like the problem is with compiling main.c.  That's when it is
looking for the header files.  It isn't linking yet.  That is what
TARGET_LINK_LIBRARIES is for.

Not sure if this is the right solution, but maybe you can give it a
try; that is what I'm doing.
