[CMake] problem creating a library on mac

[John Doe]

Did you run nm on the library containing these symbols to verify they exist?

_tetra_zone_copy_
_xyz_vertex_copy_

The trailing underscore is reminiscent of a Fortran compiler.  Are you using
the write convention when calling these functions from C code?  On Linux,
you would call the Fortran function foo as foo_.

Should you be linking against libm, if you are getting the same symbols from
libimf.a?

ld: warning multiple definitions of symbol _modf
/opt/intel/cc/10.0.016/lib/libimf.a(modf_stub.o) definition of _modf in
section (__TEXT,__text)
/usr/lib/gcc/i686-apple-darwin8/4.0.1/../../..//libm.dylib(xmm_floor.o)
definition of _modf

Regards,

Juan
