# 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 do a non cross compile build (e.g. windows in MSVC
# or windows in cygwin) first, or download the generated files from mupdf.com.
