From 71f8b809b2e650755dee9b7d5005c889a6bd3ae1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Wed, 29 Sep 2021 15:47:08 +0200 Subject: bullet: Sync with upstream 3.17 Stop include Bullet headers using `-isystem` for GCC/Clang as it misleads SCons into not properly rebuilding all files when headers change. This means we also need to make sure Bullet builds without warning, and current version fares fairly well, there were just a couple to fix (patch included). Increase minimum version for distro packages to 2.90 (this was never released as the "next" version after 2.89 was 3.05... but that covers it too). Fixes #43868.
