# Sample toolchain file for building for Windows from an OS X system.
#
# Typical usage:
#    1) install a mingw-w64 cross compiler
#       a) darwin toolchain targeting win32: http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win32/
#       b) extract toolchain into ~/mingw/w32
#    2) cp cmake/Toolchain-OSX-mingw32.cmake.sample ~/Toolchain-OSX-mingw32.cmake
#    3) tweak toolchain values as needed
#    4) cd build
#    5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-OSX-mingw32.cmake ..

# name of the target OS on which the built artifacts will run
# and the toolchain prefix
