From e8b6b7adc138a66f8d47396a2e707366d3771028 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Mon, 31 Dec 2018 18:42:09 +0100 Subject: [PATCH] buildsystem: relax requirement on cmake version Commit 73cc5089 (Using target_compile_features to specify C++ 11 standard) bumped the required cmake version, from 3.0 to 3.8, so as to get the definition of target_compile_features(). However, target_compile_features() was introduced in cmake-3.1: https://cmake.org/cmake/help/v3.1/command/target_compile_features.html And using cmake-3.1 is indeed sufficient to properly build. As such, relax the minimum required version down to cmake-3.1, so we can build on oldish, entreprise-grade distributions that only have cmake-3.1 (or at least, don't have up to cmake-3.8).
