# The following section is an example of how to simply do cross-compilation
# using these Makefiles. It builds for a beagleboard running ARM linux,
# compiling on windows with the CodeSourcery G++ compilers.
# Invoke this as:
#      make OS=beagle-cross build=release
# This does rely on the generated directory being populated with the cmap
# files etc first. Either:
#   1) do 'make generate' first (this relies on you having an appropriate host
#   base C compiler set up - such as you would have on unix or in windows
#   cygwin)
#   2) do a non cross compile build (e.g. windows in MSVC) first.
#   3) download the generated files from mupdf.com.
