# Build/install the iree-compiler python package.
# Note that this includes a relatively large build of LLVM (~2400 C++ files)
# and can take a considerable amount of time, especially with defaults.
# To install:
# pip install .
# To build a wheel:
# pip wheel .
#
# It is recommended to build with Ninja and ccache. To do so, set environment
# variables by prefixing to above invocations:
# CMAKE_C_COMPILER_LAUNCHER=ccache CMAKE_CXX_COMPILER_LAUNCHER=ccache
#
# On CIs, it is often advantageous to re-use/control the CMake build directory.
# This can be set with the IREE_COMPILER_API_CMAKE_BUILD_DIR env var.
#
# Select CMake options are available from environment variables:
# IREE_ENABLE_CPUINFO
