If using cmake outside of MacPorts you could accidentally write files to
/opt/local which are out of control of MacPorts. I think /usr/local is a
more reasonable default. Ports using cmake can still overwrite it in the
 Portfile.

To do this automatically we could think about a cmake portgroup (maybe
wait for #14553) or support it in base as a new build.type, as the
number of ports using cmake seems to grow.
