# Build/install the npcomp-core 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 . --use-feature=in-tree-build
# To build a wheel:
# pip wheel . --use-feature=in-tree-build
#
# It is recommended to build with Ninja and ccache. To do so, set environment
# variables by prefixing to above invocations:
# CMAKE_GENERATOR=Ninja 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 NPCOMP_CMAKE_BUILD_DIR env var.
