From 85f92d0a19f1eab321a6eabdd65b300cd16e61d3 Mon Sep 17 00:00:00 2001 From: Rainer Hurling Date: Tue, 2 Sep 2025 09:06:20 +0200 Subject: math/nlopt: Fix build with Octave installed cmake requires at least C++17 to build correctly if math/octave is already installed. math/octave is now a fixed dependency for nlopt, as this is the only way to guarantee that Octave packages such as math/octave-forge-mboct-fem-pkg will find a sufficiently complete nlopt.
