From 050b205a97c4dc0b9819fd2eea1fbe78cc1981ec Mon Sep 17 00:00:00 2001 From: Jacques Lucke Date: Wed, 24 Nov 2021 11:40:26 +0100 Subject: CMake: add WITH_UNITY_BUILD option to improve compile times Unity builds are only used in the `bf_nodes_geometry` module for now. This module has been prepared to support unity builds already. Usually, there is a 2-4x speedup when building `bf_nodes_geometry` compared to without unity builds (e.g. 145s to 55s). For more information about how unity builds work and how they help with compile times, see D13341.
