This is all part of the cmake setup of lang/swipl, and currently I use an awful patch to hardcode something in the cmake file pre-make - but this file actually allows one to set a variable - $LibUUID_ROOT - to the path of uuid-config from the outside. I have successfully experimented with this, so I added:

The proper and canonical solution for this problem is

-DLibUUID_ROOT=${LOCALBASE}

Ports should expect their dependencies to be installed under ${LOCALBASE}.
