No, it does work, just set
CC=/usr/local/libexec/ccache/cc
(where /usr/local/libexec/ccache/cc is a link to you compiler)
or use the way recommended in share/doc/ccache/ccache-howto-freebsd.txt:
setenv PATH /usr/local/libexec/ccache:$PATH
setenv CCACHE_PATH /usr/bin:/usr/local/bin
The only case when cmake refuses to work with ccache is when CC is set to
something like this:
CC=ccache cc
But this may be fixed in future (if not fixed already)

You don't need to define _CMAKE_TOOLCHAIN_PREFIX. I believe this is the cause
of your problem.
