[CMake] cpack 32bit rpm on a 64bit system

[Yngve Inntjore Levinsen]

Dear Eric,

First, thank you for a very quick reply!

The log you requested is attached. The rpmbuild.out file is empty, and the rpmbuild.err has one line which states:
error: No compatible architectures found for build

I am using cmake/cpack version 2.6-patch 4. I have rpmbuild version 4.4.2.3.

Why I am doing it? I suppose it is a rather weird request, but I want to build a 32bit binary on my 64bit server and distribute the program to many people that still use a 32bit machine. In order to have maximum compability, it has been decided that we should provide a statically linked 32bit executable. It is not necessary to provide this in an rpm of course, but it would be nice if it was possible. 

Thank you for your help!

Cheers,
Yngve
