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

[Yngve Inntjore Levinsen]

Dear Eric,

So I answered my own question perhaps, the very issue was in fact that I set CPACK_RPM_PACKAGE_ARCHITECTURE to i686 when I tried to build. Commenting out that part and the packaging worked.

Two questions:

- Will this package now be installable on both 32 and 64bit systems? If not, can I get it to be installable on both architectures somehow?

- Why shouldn't I set the variable?

Cheers,
Yngve
