-# Android CMake toolchain file, for use with the Android NDK r5-r7
+# Android CMake toolchain file, for use with the Android NDK r5-r8
# Requires cmake 2.6.3 or newer (2.8.3 or newer is recommended).
# See home page: http://code.google.com/p/android-cmake/
#
#
# Usage Windows:
# You need native port of make to build your project.
-# Android NDK r7 already has make.exe on board.
+# Android NDK r7 (or newer) already has make.exe on board.
# For older NDK you have to install it separately.
# For example, this one: http://gnuwin32.sourceforge.net/packages/make.htm
#
# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME}
# (depending on the target ABI). This is convenient for Android packaging.
