All other things being equal, I'd say the best way to handle, for example, 
libcap would be "use it if it's available, don't use it if it's not", so the 
user doesn't *have* to specify stuff on the command line - I've occasionally 
seen people advocate setting CFLAGS as a way to deal with autoconf-script 
issues, but I tend to think that any time you have to do anything more than 
configure/make/make install to install from an autoconf-based source tarball 
that's probably a bug, and would extend that to "any time you have to do 
anything other than run 'cmake .' to build, that's probably a bug".

So I'd say allowing ON, OFF, or OPT (or IFAVAILABLE, or whatever) as values for 
most of the packages - and defaulting to OPT/IFAVAILABLE/etc. - would make 
sense (and would mirror what we do with autoconf; if you want to make *sure* 
you're using libcap, configure with --with-libcap, and if the configure fails, 
do what's necessary to make it succeed, e.g. actually install the development 
package for libcap).  Some packages default to "yes" rather than "yes, if 
available" in autoconf - e.g., libpcap, so that you have to ask for a version 
of *Shark that doesn't support packet capture, rather than being surprised by 
such a version if the configure script somehow fails to find libpcap - and 
those should work the same way with cmake.
