# Cap'n Proto AppVeyor configuration
#
# See https://www.appveyor.com/docs/appveyor-yml/ for configuration options.
#
# This script configures AppVeyor to:
#   - Download and unzip MinGW-w64 4.8.5 for x86_64, the minimum gcc version Cap'n Proto advertises
#     support for.
#   - Use CMake to ...
#       build Cap'n Proto with MinGW.
#       build Cap'n Proto with VS2015 and VS2017.
#       build Cap'n Proto samples with VS2015 and VS2017.
