cross-build-mingw.sh

#!/bin/sh
# A script to automate setup and build for Windows cross-compilation
#
# What it does:
# 1) prepare a build directory
# 2) download and unpacked the dependencies
#    (see http://www.gtk.org/download/win32.php)
# 2.1) fixup the unpacked pkg-config file paths
# 3) setup the few required paths
# 4) configure with sensible options for this
# 5) build
# 6) install in a local directory
# 7) pack the installation in a ZIP file, ready to be used
#    (but does not pack the dependencies)

# You may change those
