# Filesystem layout considerations...
# for this explanation I assume that your Subsurface sources are in
# ~/src/subsurface
#
# You need to have a version of Qt that contains the Android bits
# installed. You should be able to find the correct installer for
# Linux or Mac here:
# http://download.qt.io/official_releases/qt/5.7/
# make sure you pick one with 'android' in its name.
#
# Install this wherever you want - and then have a link named ~/src/Qt that
# points to it.
# So let's assume that you are installing the package above in ~/Qt5.7.1
# (which I think is the default location), then simply do
# cd ~/src
# ln -s ~/Qt5.7.1 Qt
#
# you also need to have the current Android SDK and NDK installed under ~/src
#
