From 206c38e6f921998255a1682ef3dc66d3e8ce1eab Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 2 Apr 2026 22:14:43 +0200 Subject: [PATCH] cmake: use writev(3p) wrapper as needed This is a companion patch of 3b9b2c2a29a (compat/posix: introduce writev(3p) wrapper, 2026-03-13) where support for using the `writev()` wrapper was introduced in the `Makefile` and the Meson-based build, but the CMake build still needs that treatment, too.
