# This requires GNU make, curl, openssl, tar, unzip, patch, and a working
# mingw32 toolchain.  Just set host and prefix and away you go!
#
# Example usage:
#   make -f deps.mk -j2 host=i486-mingw32 prefix=/usr/i486-mingw32
#   sudo make install
#
# A lot of temporary files and directories are downloaded or extracted to the
# current directory, so you may want to make from a clean directory.
