There are rpms & instructions for an earlier sme version (7.2) here.
http://distro.ibiblio.org/pub/linux/distributions/smeserver/contribs/rmitchell/smeserver/contribs/zoneminder/Looks like it is for the 2.6.9-67.0.1 kernel
As I understand it, Zoneminder has quite specific requirements and various modules must be compiled for the specific kernel in use. The original maintainer (sognenovski) is no longer supporting the contrib, and as far as I know, nobody else is updating the rpms for the current sme release (and kernel).
You could try installing those rpms (listed above) on a test sme 7.2 (that has been upgraded with the appropriate kernel), to see if you can get it working, and then address the issue of compiling for the current OS kernel.
Otherwise ask someone here who is knowledgable to have a go at compiling "whatever is required", but as implied, zoneminder & related packages will need updating for each new kernel release, so a maintainer is really needed.
PS As far as settings are concerned, you can open Midnight Commander, type mc at the command prompt, and view the rpms to see what changes are made to the system when it gets installed. That should give you very good clues. Download and copy the rpms to your server first of course (use the wget command).
I installed ZM 1.22.3 on my server
Out of interest, what install steps did you use or follow ?
