From 236d6244a0f44fbe0f50f16fb259a3817ce463c4 Mon Sep 17 00:00:00 2001 From: Brad King Date: Fri, 11 Nov 2016 14:50:50 -0500 Subject: [PATCH] Android: Always set CMAKE_ANDROID_NDK_TOOLCHAIN_VERSION When this variable is not set by the user or toolchain file, set it to the default selected. This will be useful for client code that needs to pass the value to an external tool that needs to find the same toolchain in the NDK. Leave it empty for a standalone toolchain.
