# While Bazel (http://bazel.io) is the primary build system used by cctz,
# this Makefile is provided as a convenience for those who can't use Bazel
# and can't compile the sources in their own build system.
#
# Suggested usage:
#
# To build locally:
# make -C build -f ../Makefile SRC=../ -j `nproc`
#
# To build/install a versioned shared library on Linux:
# make -C build -f ../Makefile SRC=../ -j `nproc` \
# SHARED_LDFLAGS='-shared -Wl,-soname,libcctz.so.2' \
# CCTZ_SHARED_LIB=libcctz.so.2.0 \
# install install_shared_lib
