# Build every WASM artifact downstream projects need, from a clean checkout.
# Produces the four static libraries that (e.g.) concept-collection/matmul-bench
# links against:
#
#   install/lib/libflame.a            single-threaded libflame
#   install/lib/libflame-mt.a         libflame compiled with -pthread
#   install/lib/libblis-st.a          single-threaded BLIS (BLAS backend)
#   blis/lib/generic/libblis.a        BLIS compiled with pthreads
#
# Each variant is built in a freshly re-cloned tree (rm -rf before each build):
# the single- and multi-threaded objects differ only by compile flags, and
# libflame's make does not rebuild objects when just config.mk changes, so a
# clean tree is the only reliable way to get correct -pthread archives.
#
# This is slow (libflame is built twice, BLIS twice). Downstream CI should
# cache the outputs keyed on this repo's commit SHA.
#
# Requires: emsdk (expected at ~/emsdk, or already on PATH), git, a C toolchain.
