In most cases, yes, in this case it's not just undefined but defined as
either non-existent or a symlink to /opt/local.

If the standard ignored it, that would be true. It doesn't.

I think a better solution is to define /usr/local as a symlink
to /opt/local in the install, and set cmake to look there. That is in line
with what the standard says (it's practically recommended), allows cmake to
find it (by searching for things in /opt/local, where they should be), and
has the effect the user expects.
