From 46e19cb45f4d24a255ef445d2505290b089bcfdd Mon Sep 17 00:00:00 2001 From: Matthias Maier Date: Wed, 25 May 2022 18:07:23 -0500 Subject: [PATCH] CMake: Skip expensive boost test This has been finally fixed upstream sometime in late 2018 [1], and this runtime check is very expensive. Let us skip it for a safe, good version. I have chosen 1.74 semi randomly because it has been released in 2020 and is the boost version found in Debian 11.
