# We need this file only during compilation process itself so we need it for our "host"
# platform, not "target" platform.
# If we are doing normal compilation this executable will be produced in grpc.cmake.
#
# All code inside this block looks so weird because cmake fundametally doesn't
# support different toolchains for different targets. So we just running it
# in "bash script" fashion with different (actually without, i.e. default) toolchain.
#
# FIXME Sorry, I don't know cmake.
