# This is an example showing a basic makefile that links in the IREE runtime by
# way of the unified static library. It's recommended that IREE is added as a
# subproject and cmake is used to add the dependencies (as in the CMakeLists.txt
# in this directory) but when using other build systems this is easier to adapt.
#
# Configure the runtime:
#   cmake -GNinja -B ../iree-build-runtime/ . \
#       -DCMAKE_BUILD_TYPE=MinSizeRel \
#       -DIREE_SIZE_OPTIMIZED=ON
# Build the runtime:
#   cmake --build ../iree-build-runtime/ --target iree_runtime_unified
# Make this binary:
#   make custom-module-run-min RUNTIME_BUILD_DIR=../iree-build-runtime/
#
# Note that if IREE_SIZE_OPTIMIZED is used to build the runtime then the
# -DNDEBUG and -DIREE_STATUS_MODE=0 are required on any binaries using it.
