-From fc126942abe7e507c75f12da2f6d51b70c829736 Mon Sep 17 00:00:00 2001
-From: Robert Adam <dev@robert-adam.de>
-Date: Wed, 30 Nov 2022 19:09:46 +0100
-Subject: Cpp: Add cmake options to selectively disable shared/static build
-
-The default behavior is left unchanged (build both) but now users can
-choose to optionally only build one of the two variants.
-Due to macro-magic, both variants had to be compiled separately and
-therefore building both variants really does compile everything twice.
-Therefore, disabling the version that one is not interested in can cut
-down compilation time significantly.
-
-Fixes #3993
