# 20261020 bkw:
# - take over maintenance. the new fsv requires this.
# - update for v0.9.6.
# - remove all the build options except building the docs, and make
#   that DOCS instead of CGLM_BUILD_DOCS. it defaults to yes, but
#   really it autodetects the optional deps and skips building
#   the docs if they're missing.

# 20261020 bkw: No SLKCFLAGS here. This library is "highly
# optimized", so we'll go with upstream's default flags. If we set
# CMAKE_C_FLAGS_RELEASE, it just puts -O3 after our -O2 anyway. And
# it always builds with -fPIC. Also, it's smart enough to get lib vs.
# lib64 right by itself.
