# Cross-compiling requires CMake 2.6 or newer. To cross-compile, first modify
# this file to set the proper settings and paths. Then use it from build/ like:
# cmake .. -DCMAKE_TOOLCHAIN_FILE=../XCompile.txt \
#          -DCMAKE_INSTALL_PREFIX=/usr/mingw32/mingw
# If you already have a toolchain file setup, you may use that instead of this
# file.
