From fc5fa79a857945f252c967b6411fcd8f3a297d6b Mon Sep 17 00:00:00 2001 From: Rafael Palomar Date: Fri, 27 Oct 2023 10:24:41 +0200 Subject: [PATCH] ENH: Enable propagation of linker flags This change allows customizing the linker flags at the superbuild level. The motivation behind this modification was to enable the use of the gold linker in 3D Slicer, as referenced in https://github.com/Slicer/Slicer/pull/7294, to expedite the linking phase during the build process.
