# This is a cmake-toolchain(5) file that can be used to cross-build
# cppwinrt.exe from Linux or other operating systems using a mingw-w64 cross
# toolchain. This should work with both GCC-based and llvm-mingw toolchains.
#
# Example usage with external toolchain:
#
#   $ cmake -S . -B build/cross_x64/ \
#       --toolchain cross-mingw-toolchain.cmake \
#       -DMINGW_BIN_PATH=/opt/llvm-mingw/bin \
#       -DCMAKE_BUILD_TYPE=RelWithDebInfo \
#       -DCMAKE_INSTALL_PREFIX=$PWD/install/
#
# Example usage with toolchain installed system-wide:
#
#   $ cmake -S . -B build/cross_i686/ \
#       --toolchain cross-mingw-toolchain.cmake \
#       -DCMAKE_SYSTEM_PROCESSOR=i686 \
#       -DCMAKE_BUILD_TYPE=RelWithDebInfo \
#       -DCMAKE_INSTALL_PREFIX=$PWD/install/
