# This file is called as a CustomBuild step from Chakra.ICU.Data.vcxproj.
#
# To generate the data file, we need to build GenCCode.exe for the host platform. We can then run
# GenCCode.exe --object to produce a platform-agnostic object file, which the linking step of
# Chakra.ICU.Data should be able to link into a DLL for the target platform.
