From 6e826c471b7f0431391a4e9f9484f6ea2833774a Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Mon, 28 Jan 2019 14:53:19 +0100 Subject: [PATCH] Android build: use ANDROID_NDK_HOME rather than ANDROID_NDK It apepars that ANDROID_NDK_HOME is the recommended standard environment variable for the NDK. We retain ANDROID_NDK as a fallback.
