Which version of CMake/CPack ?

Could you send me the log obtained with:

cpack -V -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM

and send me the advertised "rpmbuild.err,  rpmbuild.out,
<yourpackageName>.spec" files?

Some more questions:

What is your linux distribution ?
How did you build the 32bits binaries  with CMake (? add -m32 using CFLAGS?) ?

RPM packaging of 32bits apps on 64bits may not be portable at all,
why are you trying to do that ?
